Executive Summary
Background
On May 7, 2010, the Environmental Protection Agency (EPA) and the National Highway Traffic
Safety Administration (NHTSA) issued a joint Final Rule to establish the first phase of a
National Program with new standards for 2012 to 2016 model year light-duty vehicles that
reduce greenhouse gas (GHG) emissions and improve fuel economy. These standards apply to
passenger cars, light-duty trucks, and medium-duty passenger vehicles. Subsequently, on
October 15, 2012, EPA and NHTSA issued standards for GHG emissions and fuel economy of
light-duty vehicles for model years 2017-2025, building on the first phase of the joint National
Program.
EPA is releasing this report as part of our continuing commitment to provide the public with
transparent and timely information about manufacturers' compliance with the GHG program.1
This report supersedes previous reports and details manufacturers' performance towards meeting
GHG standards in the 2015 model year, the fourth year of the GHG standards which become
increasingly stringent in each model year from 2012 through 2025. All data are final through the
end of the 2015 model year. Some values from previous model years may have changed based
on changes or corrections to the historical data.2
The following figure illustrates the process and the inputs that determine a manufacturer's
compliance with the light-duty vehicle GHG emission standards. Every manufacturer starts at the
same place: by measuring the CO2 tailpipe emissions performance of their vehicles using EPA's
City and Highway test procedures (referred to as the "2-cycle" tests). Then they may choose to
apply a variety of optional technology-based credits to further reduce their fleet GHG emissions
compliance value. The 2-cycle tailpipe CO2 value, when reduced by the net grams per mile
equivalent of the optional credits, determines a manufacturer's model year performance and
whether credits or deficits are generated by a manufacturer's model year fleet.
It is important to note that the Department of Justice, on behalf of EPA, alleged violations of the
Clean Air Act by Volkswagen and certain subsidiaries based on the sale of certain model year
2009-2016 diesel vehicles equipped with software designed to cheat on federal emissions tests.
In this report, EPA uses the CO2 emissions data from the initial certification of these vehicles.
Should the investigation and corrective actions yield different CO2 data, the revised data will be
used in future reports. For more information on actions to resolve these violations, see
www.epa.gov/vw.

Information Center: http://www.nlitsa.gov/CAFE PIC/CAFE PIC Home.htm.

final EPA decisions or positions regarding the data or the compliance status of manufacturers.

Individual model year performance, however, does not directly determine model year
compliance or non-compliance. Manufacturers with deficits in a model year may use credits
carried over from a previous model year to offset a deficit. They may also purchase credits from
another manufacturer. Manufacturers with a deficit at the conclusion of a model year may also
carry that deficit forward into the next model year. Manufacturers must, however, offset any
deficit within three years after the model year in which it was generated to avoid enforcement
action. After considering these additional credits and deficits, EPA determines a manufacturer's
current compliance status. For example, a manufacturer with a deficit from 2012 remaining after
the 2015 model year would be considered out of compliance with the 2012 model year standards.
There are no manufacturers that ended 2015 in this position. Jaguar Land Rover, for example,
successfully offset 2012 and 2013 deficits by the end of the 2015 model year and is thus in
compliance with the program to date. No manufacturer is yet out of compliance with the GHG
program in these first four model years; their performance in subsequent years, and whether
deficits can be successfully offset using future credits (either generated or acquired) will
ultimately determine final compliance.

-------
For the fourth consecutive year, the auto industry
outperformed the GHG standard by a substantial margin
Overall industry performance in model year 2015 was 7 g/mi better than required by the 2015
GHG emissions standard. This marks the fourth consecutive model year of industry
outperforming the standards by a sizeable margin. This industry-wide performance means that
manufacturers are offering and consumers continue to buy vehicles with lower GHG emissions
than required by the EPA standards. Manufacturers continued this level of performance against
standards that increased dramatically in stringency in model year 2015. The standards increased
in stringency by 13 g/mi relative to model year 2014; to put this in perspective, the total
cumulative increase in stringency since the start of the program is 25 g/mi. Although the
"compliance margin" narrowed to 7 g/mi, this remains notable in the face of a continuing
increase in truck market share combined with the increased stringency. See Section 3 for more
detail on these values.3

Most manufacturers outperformed their individual 2015
standard
Most large manufacturers achieved fleet GHG compliance values equal to or lower than required
by their unique 2015 standard. Nine of the twelve manufacturers with sales greater than 150,000
vehicles reported meeting or beating their standard, with margins of compliance ranging from 23
g/mi (Nissan and Subaru) to exactly meeting their standard with no margin (BMW). Three
manufacturers (FCA, Mercedes, and Kia) missed their unique 2015 standards by 3, 11, and 12
g/mi, respectively, thus generating net deficits in the 2015 model year. The figure below does not
include the impact of credit transfers reported from prior model years (within a company) or
reported credit trades (transactions between companies), and thus does not necessarily portray
whether or not a manufacturer has complied with the 2015 model year standards. The three
manufacturers that did not outperform their 2015 standard in fact have reported sufficient credits
from prior model years to be able to report compliance with their respective 2015 model year
standards. More detail about model year 2015 performance is provided in Section 3.

corrective actions yield different CO2 data, the revised data will be used in future reports.

3 All large manufacturers are in compliance with the 2012-2015
GHG standards
The majority of manufacturers, representing more than 99 percent of 2015 model year U.S. sales,
have reported compliance with the standards for the 2012-2015 model years. In fact, 19 of 20
manufacturers are reporting a non-negative credit balance going into the 2016 model year,
meaning that these manufacturers have met the standards in all of the 2012-2015 model years
(credits cannot be carried forward if a deficit exists in a prior model year). Manufacturers are
allowed to carry deficits forward for three model years. Thus, a manufacturer with a deficit from
the 2012 model year must have offset that deficit by the end of the 2015 model year, or else be
subject to possible enforcement action. All manufacturers that initially reported a deficit in the
2012 model year have successfully offset that deficit, thus no manufacturer is in a position of
non-compliance for any model year at the end of the 2015 model year. The makeup of these
credit and deficit balances is tracked by model year "vintage" as explained in Section 5.

1. Introduction
A. Why Are We Releasing This Information?
We are releasing this report as part of our continuing commitment to provide the public with
transparent and timely information about manufacturers' performance under EPA's GHG
program. In the two regulatory actions that established new GHG emissions and fuel economy
standards for light-duty vehicles, EPA and NHTSA committed to making certain information
public regarding the compliance of automobile manufacturers with the CO2 and fuel economy
standards.6 7 This report is the fifth such report released regarding EPA's GHG program.
Because of changes that propagate back to prior model years, such as the buying and selling of
credits by manufacturers, prior reports should be considered obsolete and are superseded by this
report.
When EPA and NHTSA issued the proposed rule for the 2012-2016 model year CO2 and fuel
economy standards, the proposal received considerable comment about the need for transparency
regarding implementation of the program, and specifically, regarding compliance
determinations.8 Many comments emphasized the importance of making GHG compliance
information publicly available to ensure such transparency. This was also the case with the
proposal for 2017-2025 model year GHG standards, in which we reiterated our commitment to
the principle of transparency and to disseminating as much information as we are reasonably,
practically, and legally able to provide.9 In response to the comments on the proposed rule for
2012-2016 model year standards we noted that our public release of data could include ".. GHG
performance and compliance trends information, such as annual status of credit balances or
debits, use of various credit programs, attained fleet average emission levels compared with
standards, and final compliance status for a model year after credit reconciliation occurs" and
that we would ".. .reassess data release needs and opportunities once the program is
underway."10
In the final rule for model years 2017-2025, we also committed to expanding the information we
release regarding GHG program compliance, noting in the preamble that ".. EPA intends to
publish the applicable fleet average standards (for cars and for trucks) and the actual fleet
performance for each manufacturer, and the resulting credits or debits." Further, we stated that
we anticipate publishing ".. .the amount of credits generated by each manufacturer (separately
for each of the car and truck fleets) under the optional credit programs, and the associated
volumes of vehicles to which those credits apply." We also suggested that we would likely

consult the regulatory announcements and associated technical documents for a detailed description of the program.

public information center. See http://www.nlitsa.gov/CAFE_PIC/CAFE_PIC_Home.htm.

publish credit transactions, as well as the overall credit or debit balance for each manufacturer
after taking into account the credit and debit carry-forward provisions and any credit
transactions.
In addition to this and prior reports, we continue to release a considerable amount of information
regarding fuel economy, emissions, and vehicle characteristics for each vehicle model. For
example, starting with the 2013 model year, the downloadable data available at fueleconomy.gov
includes CO2 emission values for each vehicle model. In addition, we release actual vehicle
emission test results at epa.gov/otaq/tcldata.htm. Finally, detailed information on long-term
industry-wide CO2, fuel economy, and technology trends since model year 1975 are at
epa.gov/otaq/fetrends.htm. This latter report does not contain formal compliance data, but rather
focuses on EPA's best estimates of real world CO2 emissions and fuel economy.
B. What Data Are We Publishing?
The EPA GHG program requires compliance with progressively more stringent GHG standards
for the 2012 through 2025 model years. The program includes certain flexibilities, several of
which were designed to provide sufficient lead time for manufacturers to make technological
improvements and to reduce the overall cost of the program, without compromising overall
environmental objectives. The 2015 model year is the fourth year manufacturers have been
subject to the standards. This report makes comparisons across the four complete model years of
the GHG program where appropriate. This report contains updated data for previous model years
and supersedes previous reports regarding manufacturer compliance with EPA's GHG program.
The manufacturer-reported data which form the basis for this report was required to be submitted
to EPA by May 1 of 2016.11 The data reported by each manufacturer includes the calculated
manufacturer-specific footprint-based CO2 standard for each vehicle category (car and truck), the
actual fleet-average tailpipe performance for each vehicle category (which includes flexible-fuel
vehicle credits and credits for other alternative fuels such as compressed natural gas and
electricity), the quantity of optional credits (e.g., based on air conditioning or off-cycle
technology improvements), credit transfers within a manufacturer between car and truck fleets,
credit trades between manufacturers, if applicable, and all the data necessary to calculate these
reported values.
This report first updates and summarizes the credits reported by manufacturers under the early
credit provisions, and then summarizes the data reported by manufacturers for the 2012-2015
model years in a variety of ways. This includes separately detailing manufacturers' reported use
of the flexibilities included in the program (e.g., credits for air conditioning improvements or
production of flexible-fuel vehicles), as well as the credit transactions between manufacturers.
Vehicle and fleet average compliance for EPA's GHG program is based on a combination of
CO2, hydrocarbons, and carbon-monoxide emissions (i.e., the carbon-containing exhaust
constituents). This is consistent with the carbon balance methodology used to determine fuel
consumption for the vehicle labeling and CAFE programs. The regulations account for these
total carbon emissions appropriately and refer to the sum of these emissions as the "carbon-
11 See 40 CFR 600.512-12.

-------
related exhaust emissions," or "CREE." The carbon-containing emissions are combined on a
C02-equivalent basis to determine the CREE value, i.e., adjusting for the relative carbon weight
fraction of each specific emission constituent. Although the regulatory text uses the more
accurate term "CREE" to represent the C02-equivalent sum of carbon emissions, the term CO2 is
used as shorthand throughout this report as a more familiar term for most readers.
The CO2 standards in EPA's GHG program and the related compliance values in this report
differ from the CO2 values reported in EPA's "Trends" report or on new vehicle fuel economy
labels.12 The Trends report presents CO2 and fuel economy values that are based on EPA's label
methodology, which is designed to provide EPA's best estimate of the fuel economy and GHG
emissions that an average driver will achieve in actual real-world driving. EPA's CO2 standards,
like the CAFE standards, are not adjusted to reflect real world driving. Instead, the GHG
standards and compliance values are based on the results achieved on EPA's city and highway
tests, weighted 55 and 45 percent, respectively. These tests are conducted under ideal driving
conditions and do not reflect a number of driver and environmental conditions that impact real
world fuel economy. Results from these two tests are commonly referred to as the "2-cycle" test
procedures, in that they are based on weighted results from two unique driving cycles. The CO2
values that appear in the Trends report and on the EPA fuel economy window stickers will be
about 25 percent higher than those in this report, and are based on what is frequently referred to
as the "5-cycle" methodology, because the results are based on five different test procedures. The
5-cycle methodology includes tests that capture the impacts of aggressive driving, cold
temperatures, and hot temperatures with air conditioning operating, among other factors. None of
these factors are reflected in the 2-cycle tests used to determine compliance with CAFE and
GHG standards.
Credits are expressed throughout this report in units of Megagrams (Mg), which is how credits
are reported to EPA by the manufacturers.13 Further, compliance is ultimately determined based
on the balance of Megagrams of credits and/or deficits for a given model year, after accounting
for credit transfers and trades. In order to present the impact of these credits in terms that might
be more understandable and are comparable equitably across manufacturers, we calculate and
present a grams per mile equivalent value where possible (see inset on this page for the
methodology used to convert Megagrams to grams per mile).14 Where such a value in a table
applies to a specific manufacturer, the grams per mile value represents the impact of credits on
the fleet of that specific manufacturer, whereas the final Fleet Total row displays the grams per
mile impact of the total credits across the entire model year fleet of cars, trucks, or combined
fleet, whichever may be applicable. Finally, this report does not attempt to summarize or explain
all of the elements or details of EPA's GHG program. Readers should consult EPA's final
regulations and supporting documents for additional information.

13	The Megagram (Mg) is a unit of mass equal to 1000 kilograms. It is also referred to as the metric ton or tonne.
14	The quantity of Megagrams generated by a manufacturer is based on production volume, thus, larger
manufacturers will produce larger balances of credits or deficits. Because of the connection to production volume,
comparing Megagrams across manufacturers isn't meaningful, e.g., a higher volume of credits in Megagrams does
not necessarily indicate better performance relative to the standard relative to other manufacturers with fewer
credits.

America Chattanooga Operations, LLC, Porsche AG, and Porsche Cars North America, Inc. for
alleged violations of the Clean Air Act. The U.S. complaint alleges that certain model year 2009-
2016 diesel vehicles are equipped with defeat devices in the form of computer software designed
to cheat on federal emissions tests, and that during normal vehicle operation and use, the cars
emit levels of oxides of nitrogen (NOx) significantly in excess of the EPA compliant levels. For
more information on actions to resolve violations, see www.epa.gov/vw. Oxides of nitrogen
emissions are not directly related to tailpipe CO2 emissions or fuel economy. In this report, EPA
uses the CO2 emissions data from the initial certification of these vehicles. Should the
investigation and corrective actions yield different CO2 data, the revised data will be used in
future reports. Because Volkswagen diesels account for less than 1% of industry production,
updates to the emissions rates higher or lower will not change the broader trends characterized in
this report.
C. How Can CO2 Emissions Credits Be Used?
The ability to earn and bank credits, including early credits, is a fundamental aspect of the
program's design, intended to give manufacturers flexibility in meeting the 2012-2016 model
year standards, as well as to aid in the transition to the progressively more stringent standards in
the 2017-2025 model years. Credits represent excess emission reductions that manufacturers
achieve beyond those required by regulation under EPA's program. Credit banking, as well as
emissions averaging and credit trading (collectively termed "Averaging, Banking, and Trading",
How We Determine a Grams per Mile Equivalent from Megagrams (Metric Tons) of Credits and Deficits
The Megagrams (Mg) of credits or deficits reported to EPA are determined from values expressed in grams
per mile. For example, fleet average credits/deficits are based on the difference between the fleet
standard and the fleet average performance, each of which is expressed in grams per mile. The general
form of the equation is:
Credits [Mg] = ( CO2 x VMT x Production ) / 1,000,000
"CO2" represents the credit in grams per mile. "VMT" represents the total lifetime miles, which we
specified in the regulations as 195,264 miles for cars and 225,865 for trucks. "Production" represents the
production volume to which the CO2 credit applies.
The CCh-equivalent of a credit value expressed in Mg is derived by reversing the equation as follows:
CO2 [g/mi] = ( Credits[Mg] x 1,000,000 ) / (VMT x Production )
When using this equation to calculate CO2 grams per mile for aggregate car and truck credits, we use a
weighted average of the car and truck VMT values. For example, for the entire 2015 model year fleet
covered by this report, the weighted VMT is 208,317 miles. The weighting is by the proportion of cars or
trucks relative to the total fleet. The weighting may be applied on a manufacturer-specific basis or across
the entire fleet, depending on the data presented in each table. Unless specifically stated, this is always
the source of combined car/truck fleet values in this report.

-------
or "ABT") have been an important part of many mobile source programs under the Clean Air
Act. These programs help manufacturers in planning and implementing the orderly phase-in of
emissions control technology in their production, consistent with their unique redesign
schedules. These provisions are an integral part of the standard-setting itself, and not just an add-
on to help reduce costs. In many cases, ABT programs address issues of cost or technical
feasibility which might otherwise arise, allowing EPA to set a standard that is more stringent
than could be achieved without the flexibility provided by ABT programs. We believe that the
net effect of the ABT provisions allows additional flexibility, encourages earlier introduction of
emission reduction technologies than might otherwise occur, and does so without reducing the
overall effectiveness of the program.
Credits (or deficits) are calculated separately for cars and trucks. If a manufacturer reports a net
deficit in either the car or truck category, existing credits must be applied towards that deficit.
Although a deficit may be carried forward up to three years, under no circumstances is a
manufacturer allowed to carry forward a deficit if they have credits available with which to
offset the deficit. If credits remain after addressing any deficits, those credits may be "banked"
for use in a future year, or sold or otherwise traded to another manufacturer. Credits earned in the
2010 through 2015 model years may be carried forward and used through the 2021 model year.
Credits from the 2009 model year and 2016 and later model years may only be carried forward
for five years. Thus, any early credits from the 2009 model year still held by a manufacturer after
the 2014 model year have expired and have been removed from the manufacturer's credit bank.
In addition, credits from the 2009 model year may only be used within a manufacturer's fleet,
and may not be traded to another manufacturer.15
D. Which Manufacturers and Vehicles Are Included in This Report?
The vast majority of manufacturers producing cars and light trucks for U.S. sale are currently
covered by EPA's GHG program and are included in this report. Small businesses are exempted
from the GHG program (but not from the CAFE program), and there are other manufacturers
included in this report with unique circumstances, as explained below. The report generally uses
the common and recognizable names for manufacturers, rather than their formal corporate
names; "GM" instead of "General Motors Corporation," "FCA" instead of "Fiat Chrysler
Automobiles," "Ford" instead of "Ford Motor Company," Mercedes" instead of "Mercedes-
Benz," and so on.
1. Small Businesses
Small businesses are exempt from EPA's GHG standards given that these businesses would face
unique challenges in meeting the standards. However, the program allows small businesses to
waive their exemption and voluntarily comply with the GHG standards. For example, a small
manufacturer of electric vehicles could choose to comply if they were interested in generating
GHG credits and potentially participating in the credit market. For the purpose of this exemption,
a small business is defined using the criteria of the Small Business Administration (SBA). For
vehicle manufacturers, SBA's definition of a small business is any firm with less than 1,000
15 These restrictions for the 2009 model year were established based on concerns that such credits might provide a
"windfall" since the California light truck standards from which early credits could be generated are less stringent
than the comparable CAFE standards in effect for that model year. See Section 2 for more information.
5

-------
employees. These businesses account for less than 0.1 percent of the total car and light truck
sales in the U.S., thus this exemption has a negligible impact on overall GHG reductions.
2. Small Volume Manufacturers
Similar to small businesses, some very small volume manufacturers (i.e., manufacturers with
limited product lines and production volumes that do not meet the SBA definition of a small
business) would likely find the GHG standards to be extremely challenging and potentially
infeasible. Given the unique feasibility issues faced by these manufacturers, EPA deferred
establishing CO2 standards for model years 2012-2016 for manufacturers with annual U.S. sales
of less than 5,000 vehicles.16
To be eligible for deferment in each model year, a manufacturer must demonstrate a good faith
effort to attempt to secure GHG credits to the extent credits are reasonably available from other
manufacturers. Credits, if available, would be used to offset the difference between a company's
baseline emissions and what their obligations would be under the GHG footprint-based
standards. Three manufacturers - Aston Martin, Lotus, and McLaren - requested and received a
conditional exemption for the 2012 model year. Because the 2012 model year was the first model
year of the program, and because companies seeking conditional exemptions were required to
submit their requests to EPA prior to the start of the 2012 model year, it is not surprising that a
credit market had not yet developed, despite inquiries made by these three companies of
manufacturers that were holding credits. The only manufacturers with any credits at the time
were those with optional early credits, and most were likely awaiting the conclusion of the 2012
model year to better evaluate their ability to sell credits. Because of their conditionally exempt
status for the 2012 model year, these three manufacturers were not included in EPA's report that
covered that model year.17 Since then, however, we have seen a number of credit transactions
take place, as described in Section 4 of this report. As a consequence, EPA expects small volume
manufacturers may be able to purchase credits and use them to comply with the standards in the
2013 and later model years. No conditional exemptions were approved for the 2015 model year.
Small volume manufacturers may continue to make use of certain flexibilities the program
provides for this category of manufacturers, including temporary relaxed standards and the
ability to petition EPA for alternative standards.
Acknowledging the greater challenge that small volume manufacturers might face in meeting
CO2 standards compared to large manufacturers because they only produce a few vehicle
models, EPA proposed and finalized a pathway allowing them to apply for alternative GHG
emissions standards applicable to the 2017 and later model years.18 Small volume manufacturers
with annual U.S. sales of less than 5,000 vehicles may apply for alternative standards for up to
five model years at a time, and the standards that EPA establishes for model year 2017 may
16	The deferment applies only to the fleet average CO2 standards; these manufacturers are required to meet the
applicable nitrous oxide (N20) and methane (CH4) emission standards.
17	Conditional exemptions are available only through the 2016 model year, after which manufacturers must comply
with the GHG program standards or petition EPA for alternative manufacturer-specific GHG standards. The three
manufacturers noted here have already submitted applications requesting alternative standards, and EPA is in the
process of reviewing those applications.

optionally be met by the manufacturers in the 2015 and 2016 model years. Four manufacturers
have applied for alternative standards: Aston Martin, Ferrari, Lotus, and McLaren. Because of
the likelihood that these manufacturers will choose to meet the alternative standards in the 2015
model year, and because a final determination of those standards has not been made by EPA, the
data from these manufacturers for model year 2015 have been excluded from this report. A
future edition of this report will present the data from these four companies once the applicable
standards are established.19
3.	Operationally Independent Manufacturers
Some manufacturers, even though they may be wholly or largely owned by another
manufacturer, may consider themselves to be "operationally independent" from the company that
owns them. EPA's GHG program contains provisions that allow these manufacturers to seek
separate and independent treatment under the GHG standards, rather than be considered as part
of their parent company. Manufacturers wishing to obtain operationally independent status are
required to submit very detailed information to EPA regarding their business structure, financial
operations, manufacturing operations, and management structure. The information in an
application for operationally independent status must also be verified by an independent third
party qualified to make such evaluations. Ferrari, which was owned by FCA during the 2015
model year, petitioned EPA for operationally independent status, and EPA granted this status to
Ferrari starting with the 2012 model year.20 As an operationally independent manufacturer in
model year 2015 with a low U.S. sales volume (2775 cars in the 2015 model year), Ferrari has
the same options as the three small volume manufacturers discussed above. However, Ferrari is
not included in this report for reasons described below in section l.D.2.
4.	Aggregation of Manufacturers
We refer throughout this report to the names of manufacturers at the highest aggregated level,
and it may not necessarily be readily apparent who owns whom and which brands, divisions,
subsidiaries, or nameplates are included in the results of a given manufacturer. Table 1-1 shows
how manufacturers are aggregated based on the ownership relationships and vehicle partnerships
in the 2015 model year. Many other manufacturers are covered in the report, but their names and
brands are self-explanatory and thus are not shown in Table 1-1.
19 The regulations specify the requirements for the supporting technical data and information that a manufacturer
must submit to EPA as part of its application. The process for considering such applications includes a draft
determination published by EPA followed by a public comment period of 30 days after which EPA will issue a final
determination establishing alternative standards for the manufacturer.
211 FCA announced in October 2014 the intention to spin off Ferrari into a separate, shareholder-owned company. At
the time of writing this report, the spin-off has been completed and Ferrari is now trading on the New York Stock
Exchange as an independent company. For the purpose of this report, however, Ferrari was majority-owned by FCA
and held operationally independent status for the 2015 model year.

21	Ferrari was owned by FCA in the 2015 model year. However, due to the approved operational independence
status of Ferrari (see Section 1.D.3), Ferrari is treated as a separate manufacturer for the purposes of compliance
with the GHG program in the 2015 model year.
22	In 2009 Volkswagen acquired 49.9 percent of Porsche, and in 2012 purchased the remaining 51.1 percent,
resulting in Volkswagen's full ownership of Porsche. EPA regulations allow for a reasonable transition period in the
case of mergers such as this, requiring that Volkswagen AG (including Porsche) meet the GHG standards as a single
entity "beginning with the model year that is numerically two years greater than the calendar year in which the
merger/acquisitions(s) took place." This means that Porsche was considered a separate entity under the GHG
program for the 2012 and 2013 model years, but beginning with the 2014 model year lias been considered part of
Volkswagen AG and included in the Volkswagen fleet for compliance purposes.

2. Optional GHG Credits From 2009-2011 Model
Years
One of the flexibilities in the GHG program is an optional program that allowed manufacturers
with superior greenhouse gas emission reduction performance to generate credits in the 2009-
2011 model years. Because this was an optional program, without any compliance implications
in these early model years, only those manufacturers that achieved emissions performance
beyond that required by existing California or CAFE standards chose to provide data; thus the
data does not include information for all manufacturers. Also included in the data in this section
are off-cycle credits approved by EPA; see Section 3.E for more information regarding these
credits.
Early credits were earned through tailpipe CO2 reductions, improvements to air conditioning
systems that reduce refrigerant leakage or improve system efficiency, off-cycle credits for the
implementation of technologies that reduce CO2 emissions over driving conditions not captured
by the "2-cycle" test procedures, and introduction of advanced technology vehicles (i.e., electric,
fuel cell, and plug-in hybrid electric vehicles). The optional early credits program allowed
manufacturers to select from four pathways that provided opportunities for early credit
generation through over-compliance with a fleet average CO2 level specified by EPA in the
regulations. Manufacturers wishing to earn early credits selected one of these four pathways, and
the selected pathway was followed for the three model years of 2009-2011. Since EPA's GHG
standards did not begin until model year 2012, EPA established tailpipe CO2 thresholds below
which manufacturers were able to generate early fleet average credits. For two of the pathways,
the tailpipe emission levels below which credits were available were equivalent to the GHG
standards established by California prior to the adoption of the EPA GHG program. Two
additional pathways included tailpipe CO2 credits based on over-compliance with CO2 levels
equivalent to the CAFE standards in states that did not adopt the California GHG standards. In
March of 2013, EPA released a report documenting manufacturers' use of the early credit
provisions allowed under the GHG program (the "early credits report").23
Table 2-1 summarizes the credits (or deficits) reported by manufacturers in each of the three
model years for each participating manufacturer and shows the total net early credits for each
manufacturer. The early credits program required that participating manufacturers determine
credits for each of the three model years under their selected pathway, and that they carry
forward their net credits from the three early years to apply to compliance with EPA's GHG
standards in the 2012 and later model years. Thus, even manufacturers with a deficit in one or
more of the early model years, (i.e., their tailpipe CO2 performance was worse than the
applicable emissions threshold under the selected pathway) could benefit from the early credits
program if their net credits over the three years was a positive value. Manufacturers not listed in
Table 2-1 chose not to participate in the early credits program. Additionally, this table is
intended to show the credits reported by manufacturers in these years and does not include the

impacts of any credit banking or trading on credit balances. In particular, the sale of some early
credits by some manufacturers (see Section 4), while not shown in Table 2-1, impacts the
available credit balances of the manufacturers involved in such transactions, as has the use of
early credits to offset future model year deficits. Further, while credits from the 2009 model year
may be used for compliance in 2014, any remaining unused 2009 model year credits expired
after model year 2014 and were not carried forward into the 2015 or later model years. Table 2-2
shows the total early credits reported by each participating manufacturer, broken down by the
type of credit reported. Note that the early credits program did not include credits for flexible-
fuel vehicles, whereas these credits are permitted in the 2012-2015 model years.

*Tailpipe C02 credits in the early credits program do not include credits from
flexible fuel vehicles.
Early credits from advanced technology vehicles (electric vehicles, plug-in hybrid electric
vehicles, and fuel cell vehicles) may be included in Table 2-2, depending upon how the
manufacturer chose to account for them. In these early credit years, manufacturers producing
advanced technology vehicles had two options available to them. They could simply incorporate
these vehicles into their fleet averaging in the relevant model year calculations using zero grams
per mile to represent the operation using grid electricity (see the discussion of advanced
technology vehicles in Section 3.C for more information regarding this incentive). Alternatively,
the program allowed manufacturers to exclude them from their fleet average in the 2009-2011
model years and carry the vehicles forward into a future model year, where they must be used to
offset a GHG deficit. Four manufacturers had qualifying vehicles in the 2009-2011 model years.
GM and Mercedes chose the latter approach, while Nissan and Tesla chose the former approach.
Advanced technology vehicle credits are discussed in more detail in Section 3.C which also
shows the production volumes of advanced technology vehicles for the 2009-2015 model years.
Due to concerns expressed by stakeholders during the rulemaking process, EPA placed certain
regulatory restrictions on credits from the 2009 model year.24 Specifically, 2009 model year
credits may not be traded to another company, and they retained a 5 year credit life. Thus, any
unused 2009 model year credits expired at the end of the 2014 model year. Table 2-3 shows the
credits left unused by each manufacturer at the end of the 2014 model year. These credits could
not be carried forward to the 2015 model year, and were removed from each manufacturer's
bank of credits. Note that of the almost 96 million Mg of 2009 credits earned by manufacturers,
almost 74 million Mg, or more than 75 percent, were never used and have now expired. The
expired credits also amount to about one third of the total early credits accumulated by
manufacturers in the 2009-2011 model years.

Again, previous EPA reports regarding EPA's GHG program should serve only as historical
references that are superseded by later reports. Each report is based on the best available data at
the time of publication. This report regarding the 2015 model year, and the accompanying data
as reported by manufacturers for the 2009-2015 model years, should be used as the references
from which to determine credit balances and overall performance at the conclusion of the 2015
model year, and prior reports should generally be considered obsolete.

3. Credits Reported From the 2012-2015 Model Years
The mandatory compliance calculations that manufacturers must perform are (1) to determine
credits or deficits based on manufacturer-specific, vehicle footprint-based CO2 standards for both
car and truck fleets, and (2) to demonstrate compliance with N2O (nitrous oxide) and CH4
(methane) exhaust emission standards. Compliance with CO2 standards is assessed separately for
car and truck fleets at the end of each model year, using emission standards and fleet average
values determined based on the sales-weighted actual production volumes of the model year.
Compliance with N2O and CH4 standards is typically done in conjunction with emission tests for
other pollutants, although there are additional options as described later in this report.
Although the minimum requirement is that manufacturers calculate credits (or deficits) based on
fleet average tailpipe CO2 emissions, manufacturers have several options to generate additional
credits as part of their overall strategy to reduce GHG emissions and meet the standards. These
options are described in detail in this report, and include credits for gasoline-ethanol flexible fuel
vehicles, improvements to air conditioning systems that increase efficiency and reduce
refrigerant leakage, reductions in emissions that aren't captured on EPA tests ("off-cycle"
emissions), transitional alternative standards (for eligible low-volume manufacturers), and
advanced technology vehicle incentives. The use of the optional credit provisions varies from
manufacturer to manufacturer (some manufacturers have not availed themselves of the extra
credit options, while others have used some combination of, or all, options available under the
regulations). Although a manufacturer's use of the credit programs is optional, EPA projected
that the standards would be met on a fleet-wide basis by using a combination of reductions in
tailpipe CO2 and use of the additional optional credit and incentive provisions in the regulations.
Compliance with the EPA GHG program is achieved with the use of many different building
blocks, starting with tailpipe emissions levels and, depending on need, strategy, and technology
development and availability, employing one or more credit or incentive programs as additional
elements contributing to compliance. Depending on the manufacturer, some of these credit and
incentive building blocks may or may not be used. However, all manufacturers start with the
same two mandatory building blocks: (1) GHG emissions on a grams per mile basis as measured
on EPA test procedures for each vehicle model, and (2) fleet-specific grams per mile CO2
standards based on the footprint of models produced in each car and truck fleet in a given model
year. If a manufacturer uses no credits, incentive programs, or alternative standards (if
applicable), then we can assess compliance by comparing the production-weighted fleet average
emissions from the emission tests with the fleet-specific footprint-based standards. However,
most manufacturers are using some credits, incentives, or alternative standards (if applicable),
thus for those manufacturers (and for the aggregated fleet as a whole) these building blocks must
be accounted for before determining whether or not a standard is met. Indeed, EPA's rulemaking
analysis projected that the use of credits and incentive programs was expected to be an integral
part of achieving compliance, especially in the early years of the program.
We begin by discussing the "2-cycle" tailpipe GHG emissions value (Section 3.A), which is the
starting point for compliance for every manufacturer. We then detail each of the different credit
and incentive programs, distilling each to an overall grams per mile impact for each
13

-------
manufacturer. Section 3.B describes
the temporary lead time allowance
alternative standards (TLAAS);
Section 3.C describes alternative
fuel vehicle incentives, including
the temporary flexible fuel vehicle
incentives; Section 3.D describes
credits based on air conditioning
system improvements; Section 3.E
describes off-cycle emission
reductions; and Section 3.F
discusses the impact of alternative
methane and nitrous oxide
standards. Once these values have
been determined, the 2-cycle tailpipe value is reduced by the total of all the credit and incentive
programs to determine a "compliance value," as described in Section 3.G. Section 3.H describes
the derivation of manufacturer-specific CO2 standards, which leads into Section 3.1, which
concludes Section 3, by comparing the compliance values to the CO2 standards to determine
whether or not a given fleet generates credits or deficits in the a model year. We also show
results aggregated on an industry-wide car and light truck fleet basis and an industry-wide total
combined fleet basis for informational purposes.
This report approaches the description of manufacturer compliance in the same manner as did the
previous model year reports. Instead of focusing on Megagrams of credits and deficits (which is
how credits are reported to EPA by the manufacturers), this report describes compliance (for
each manufacturer's car, truck, and combined fleets, as well as for the aggregated industry) by
describing each of the building blocks of compliance and the grams per mile contribution to a
manufacturer's total compliance. However, note that the grams per mile values are calculated
only for the purpose of this report, and are not specific compliance values defined in the
regulations.
A. "2-Cycle" Tailpipe CO2 Emissions
The starting point for each manufacturer is to test their vehicles on two test procedures defined in
EPA regulations: the Federal Test Procedure (known as the "City" test) and the Highway Fuel
Economy Test (the "Highway" test). These tests produce the raw emissions data reported to
EPA, which is then augmented by air conditioning credits, off-cycle credits, incentives for dual
fuel vehicles, and other provisions, to produce the total compliance picture for a manufacturer's
fleet. Results from these two tests are averaged together, weighting the City results by 55% and
the Highway results by 45%, to achieve a single value for each vehicle model produced by a
manufacturer. A sales-weighted average of all of the combined city/highway tailpipe values is
calculated for each passenger car and light truck fleet and reported to EPA. This value represents
the actual tailpipe CO2 emissions of a fleet without the application of any additional credits or
incentives, and as such, comparison with a fleet-specific CO2 standard would be inappropriate.
Important Note Regarding Tables
Many of tables in this section have a final row labeled
"Fleet Total." This row indicates a value that is
calculated based on the entire model year fleet and is
not specific only to the manufacturers listed in the
table. For example, not all manufacturers generated
credits for air conditioning systems, but the final
"Fleet Total" row in those tables indicates values that
are calculated to show the impact of air conditioning
credits on the entire model year fleet (i.e., across all
manufacturers, whether or not they reported air
conditioning credits).

-------
Table 3-1 shows the 2-cycle tailpipe emissions for the car, truck and combined fleets reported by
each manufacturer for the 2012-2015 model years.25 Absent the use of credits and incentives,
manufacturers demonstrated overall reductions in tailpipe GHG emissions in both the car and
truck fleets in model year 2015 relative to model year 2014. Of the 16 manufacturers active in
the program in the 2015 model year and excluding the small volume manufacturers, only GM
and Toyota increased fleet average tailpipe CO2 emissions, while the remainder reported either
no change or a decrease in the 2-cycle tailpipe emissions from their fleet. Across the industry, a
modest reduction in 2-cycle GHG emissions from cars (7 g/mi) and a sizeable reduction in 2-
cycle emissions from trucks (14 g/mi) led to a net reduction of 8 g/mi in overall fleet-wide 2-
cycle emissions. This overall reduction occurred even though the truck market share increased
from 41 to 43 percent in the 2015 model year (see Appendix B for car and truck production
data).
On a percentage basis the most significant reductions from the 2014 to the 2015 model year were
reported by Volvo (-10.7%), Nissan (-6.9%), and Honda (-6.3%). Despite reducing truck tailpipe
CO2 emissions by 16 g/mi, Toyota's overall fleet 2-cycle tailpipe emissions were up by almost
two percent, or 5 g/mi. This is likely due to an increase in car emissions of 4 g/mi coupled with a
sizeable increase in Toyota's truck production share from 35 to 43 percent. FCA and Mercedes
also made sizable gains across the board in both car and truck fleets, and Jaguar Land Rover
continued to reduce emissions, especially in the truck segment. Jaguar Land Rover and Nissan
have made the greatest percentage reductions in 2-cycle emissions - 17% - since the first year of
the program.
25 The values in Table 3-1 do not include the impacts of credits or incentives resulting from FFVs, CNG vehicles, air
conditioning improvements, and off-cycle technologies. The impacts of these are detailed in subsequent sections.
The values also reflect that direct tailpipe GHG emissions from electricity are zero. Because the values in this table
do not include these credits and incentives, the table does not describe a manufacturer's actual model year
performance or a manufacturer's compliance status.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the initial compliance data, Volkswagen's 2015 model year 2-cycle tailpipe values are 251 g/mi
for cars, 336 g/mi for trucks, and 269 g/mi for the combined fleet. Should the investigation and corrective actions yield different C02 data, the revised data will be used in future
reports.

B. TLAAS Program Standards
EPA established the Temporary Lead-time Allowance Alternative Standards (TLAAS) to assist
manufacturers with limited product lines that may be especially challenged in the early years of
EPA's GHG program. The TLAAS program was established to provide additional lead-time for
manufacturers with narrow product offerings which may not be able to take full advantage of
averaging or other program flexibilities due to the limited scope of the types of vehicles they sell.
In the 2012 model year the program was used by Ferrari, Jaguar Land Rover, Mercedes, and
Porsche. Aston Martin, Lotus, and McLaren - companies that were exempt from the 2012
standards under the program's small volume manufacturer provisions - joined the program in the
2013 model year and incorporated use of the TLAAS standards in their 2013-2015 model year
compliance. Volvo placed a small fraction of their 2015 fleet, all trucks, under the TLAAS
standards.
The TLAAS program is available only to manufacturers with 2009 model year U.S. sales of less
than 400,000 vehicles, and, except as noted below, is available during the 2012-2015 model
years. Under this program, a manufacturer is allowed to treat a portion of its fleet as a separate
averaging fleet to which a less stringent CO2 standard applies. Specifically, a qualifying
manufacturer may place up to 100,000 vehicles (combined cars and trucks) under the less
stringent standards over the four model years from 2012 through 2015 (i.e., this is a total
allowance, not an annual allowance). The CO2 standard applied to this limited fleet is 1.25 times
- or 25 percent higher than - the standard that would otherwise be calculated for the fleet under
the primary program. Providing that certain conditions are met, manufacturers with 2009 model
year U.S. sales of less than 50,000 vehicles may be allowed an additional 150,000 vehicles (for a
total of 250,000 vehicles at the 25 percent higher standard), and may be able to extend the
program through the 2016 model year (for a total eligibility of five model years).
All manufacturers participating in the TLAAS program are subject to a number of restrictions
designed to ensure its use only by those manufacturers that truly need it. Manufacturers using the
TLAAS program may not sell credits, they may not bank credits that are accrued by their non-
TLAAS fleets, they must use up any banked credits before utilizing a TLAAS fleet, and the
movement of credits between a manufacturer's TLAAS and non-TLAAS fleets is restricted.
There are four possible fleets for emissions averaging and credit or deficit calculation under the
TLAAS program: both cars and trucks in either the Primary or TLAAS program. Manufacturers
employed a variety of strategies in the use of the TLAAS program in the 2012 through 2015
model years. The smallest-volume companies (Aston Martin, Ferrari, Lotus, and McLaren)
placed all of their 2013-2014 production into a TLAAS fleet, because they can do so without any
risk of exceeding the applicable limits. As noted in section 1.D.2, 2015 model year data from
these companies is not included in this report. Porsche, which placed all of its 2012 and 2013
vehicles in the TLAAS program (totaling more than 70,000 vehicles), would have reached the
100,000 vehicle limit in the 2014 model year except for the fact that as of the 2014 model year
they are aggregated with the Volkswagen fleet and no longer eligible to use the TLAAS
program.
17

-------
Table 3-2 shows each manufacturer's reported use of the TLAAS program for the 2012-2015
model years. Note that the total of 291,930 vehicles placed under the less stringent standards in
the program to date represents less than one percent of the total vehicles produced in the 2012-
2015 model years.
While required by the regulations, the complexity of reporting credits and deficits in Megagrams
of CO2 can sometimes obscure the progress that companies are actually making towards
reducing their GHG emissions. The approach we have developed in this report provides the
transparency needed to be able to make these evaluations. For example, Mercedes-Benz and
Jaguar Land Rover, the largest of the manufacturers using these temporary and limited
alternative standards, have both made substantial progress reducing tailpipe GHG emissions
from 2012 to 2015. As shown in the previous section, Jaguar Land Rover and Mercedes reduced
their overall 2-cycle tailpipe emissions by 72 and 42 g/mi, respectively, since the program started
in the 2012 model year.

To understand the impact of the TLAAS program on compliance with EPA's GHG program, we
determined the grams per mile "benefit" achieved by each manufacturer and accrued for each
fleet as a result of using the TLAAS program. For manufacturers placing all their vehicles in a
TLAAS fleet the calculation is easy; it is simply the difference between the TLAAS program
standard and the Primary Program standard that would have otherwise applied. For
manufacturers with a mix of TLAAS and Primary Program vehicles in each fleet, we determined
the difference in the total credits (in Megagrams) for each fleet with the use of TLAAS and
without the use of TLAAS. This difference was then converted to grams per mile, and the
resulting values are shown in Table 3-3. The final row in the table indicates the overall impact
from the use of the TLAAS program on the entire model year fleet, not just the set of
manufacturers enrolled in the TLAAS program. Thus, the overall net impact on the 2015 fleet of
the TLAAS program is 0.3 g/mi. Unlike other credits, the impact of the TLAAS program is not
an adjustment to 2-cycle emissions, but rather, an adjustment to the standard. For example,
Volvo's 2015 model year fleet average standard against which they must demonstrate
compliance is 14 g/mi greater than it would be without use of the TLAAS program, as seen in
Table 3-3.

C. Credits Based on Alternative Fuel Vehicles
EPA's GHG program contains several credits and incentives for dedicated and dual fuel
alternative fuel vehicles. Dedicated alternative fuel vehicles are vehicles that run exclusively on
an alternative fuel (e.g., compressed natural gas, electricity). Dual fuel vehicles can run both on
an alternative fuel and on a conventional fuel such as gasoline; the most common is the gasoline-
ethanol flexible fuel vehicle, which is a dual fuel vehicle that can run on E85 (85 percent ethanol
and 15 percent gasoline), or on conventional gasoline, or on a mixture of both E85 and gasoline
in any proportion. Dual fuel vehicles also include vehicles that use compressed natural gas
(CNG) and gasoline, or electricity and gasoline. This section separately describes three different
and uniquely-treated categories of alternative fuel vehicles: advanced technology vehicles using
electricity or hydrogen fuel cells; compressed natural gas vehicles; and gasoline-ethanol flexible
fuel vehicles. Note that despite excluding Volkswagen from many tables for reasons described in
Section 1, they are included in this section because none of the vehicles described in this section
on alternative fuel vehicles are impacted by the ongoing investigation.
1. Advanced Technology Vehicles
EPA's GHG program contains incentives for advanced technology vehicles. For the 2012-2016
model years, the incentive program allows electric vehicles and fuel cell vehicles to use a zero
grams per mile compliance value, and plug-in hybrid electric vehicles may use a zero grams per
mile value for the portion of operation attributed to the use of grid electricity (i.e., only emissions
from the portion of operation attributed to gasoline engine operation are "counted" for the
compliance value). Use of the zero grams per mile option is limited to the first 200,000 qualified
vehicles produced by a manufacturer in the 2012-2016 model years. Electric vehicles, fuel cell
vehicles, and plug-in hybrid electric vehicles that were included in a manufacturer's calculations
of early credits also count against the production limits. As noted in Section 2, both GM and
Mercedes selected an option in the early credit provisions by which they could choose to set
aside their relatively small 2011 model year advanced technology vehicle production for
inclusion in a future model year yet to be determined.
All manufacturers of advanced technology vehicles in the 2012-2015 model years are well below
the cumulative 200,000 vehicle limit for the 2012-2016 model years, thus all manufacturers
remain eligible to continue to use zero grams per mile. If a manufacturer were to reach the
cumulative production limit before the 2017 model year, then advanced technology vehicles
produced beyond the limit must account for the net "upstream" emissions associated with their
vehicles' use of grid electricity relative to vehicles powered by gasoline. Based on vehicle
electricity consumption data (which includes vehicle charging losses) and assumptions regarding
GHG emissions from today's national average electricity generation and grid transmission
losses, a midsize electric vehicle might have upstream GHG emissions of about 180 g/mi,
compared to the upstream GHG emissions of a typical midsize gasoline car of about 60 g/mi.
Thus, the electric vehicle would have a net upstream emissions value of about 120 g/mi.26 EPA
26 Light-Duty Vehicle Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards, Final
Rule, Federal Register 75 (7 May 2010): 25435.
22

-------
regulations provide all the information necessary to calculate a unique net upstream value for
each electric or plug-in hybrid electric vehicle.27
The nature of this incentive is such that it is reflected in the 2-cycle emissions values shown in
Section 3.A. For example, the incentive allows Tesla to record zero grams per mile for their fleet
(see Table 3-1) in the 2012-2015 model years. Without the incentive, however, the 2015 model
year 2-cycle fleet average GHG emissions for Tesla would in fact be about 103 g/mi.28 Use of
the incentive in Tesla's case in the 2015 model year allows them to generate almost 490,000 Mg
of additional GHG credits relative to what they would generate by using the net upstream value
of 103 g/mi. Nissan's passenger car fleet benefits similarly from the ability of the electric Leaf to
use zero grams per mile instead of the calculated net upstream value of 72 g/mi.29 As a result, the
overall impact on Nissan's passenger car fleet in the 2015 model year is an improvement of 2.0
g/mi, allowing them to generate almost 470,000 Mg of credits more than if the incentive
provisions were not in place. The net impact from Nissan and Tesla on the entire 2015 model
year fleet of this incentive is thus about 960,000 Mg of credits, or about 0.3 g/mi. While there are
other electric vehicles and plug-in hybrid electric vehicles in the 2015 fleet, as shown in Table 3-
4, Nissan and Tesla account for a substantial fraction of the 2015 model year volume of these
vehicles. A few thousand of the remaining advanced technology vehicles are electric vehicles,
but the majority of the remaining vehicles are plug-in hybrid electric vehicles, which will have a
smaller overall impact than electric vehicles because of their use of gasoline in addition to
electricity (the other companies with larger volumes of advanced technology vehicles - General
Motors and Ford - produce far more plug-in hybrids than dedicated electric vehicles). Because it
is unlikely that the total impact of this incentive exceeds 0.5 g/mi across the 2015 model year
fleet, we have not carried out the analysis for all advanced technology vehicles. In the future,
however, it may be more important, interesting, and useful to have a complete assessment of the
impact of incentives for these vehicles. Table 3-4 shows the 2010-2015 production volumes of
advanced technology vehicles that utilized the zero grams per mile incentive.
27	See 40 CFR 600.113-12(n).
28	Using the calculations prescribed in the regulations, the sales-weighted upstream emissions for Tesla's 2015
passenger cars is 183 grams/mile and the upstream emissions associated with a comparable gasoline vehicle is 80
grams/mile. The difference, or the net upstream emissions of Tesla's 2015 passenger car fleet, is 103 grams/mile.
29	The upstream GHG emission value for the Nissan Leaf is 143 grams/mile and the upstream emissions associated
with a comparable gasoline vehicle is 71 grams/mile. The difference, or the net upstream emissions of the 2014
Leaf, is 72 grams/mile.

2. Compressed Natural Gas Vehicles
The Honda Civic CNG was the only compressed natural gas (CNG) vehicle produced for general
purchase by consumers in the 2012-2014 model years, and is a dedicated alternative fuel vehicle.
In the 2015 model year, in addition to the CNG-powered Honda Civic, Quantum Technologies
offered a dual fuel (CNG and gasoline) version of GM's Chevrolet Impala through an agreement
with GM. Quantum Technologies is exempt from GHG standards under the small business
provisions (although they could opt in if they chose), and as a result these vehicles were not
subject to 2015 model year GHG standards and won't be accounted for in this report. EPA's
GHG program contains a temporary incentive for CNG vehicles (for both dedicated and dual fuel
vehicles) that applies through the 2015 model year. This incentive, which parallels the incentive
offered these vehicles in the CAFE program, allows a CNG vehicle to be represented in the fleet
average calculation by a reduced GHG value that is determined by measuring the tailpipe
emissions of the vehicle and then multiplying by 0.15. This is effectively the same incentive as
under the CAFE program, except that fuel economy is divided, not multiplied, by 0.15.30 The
Civic CNG, which has actual tailpipe GHG emissions of 162 g/mi, is thus "counted" in Honda's
fleet average passenger car calculation with a GHG emissions value of 24 g/mi. Although the
311 Use of the 0.15 factor for GHG compliance for dedicated and dual fuel CNG vehicles sunsets after the 2015
model year. Starting with the 2017 model year a production multiplier incentive becomes effective. See the
regulations at 40 CFR 86.1866-12(b).
24

-------
vehicle-specific incentive is large (a reduction of 138 g/mi), the net impact on Honda's car fleet
is about 0.1 g/mi due to the low production volume of the Civic CNG (a few hundred in model
year 2015). This does not affect Honda's overall rounded car fleet average performance value,
and likewise has an unnoticeable impact on the overall 2015 model year fleet. If the volume of
CNG vehicles (either dual fuel or dedicated vehicles) increases substantially in the future, it will
become more important for us to be able to separate out the impact of current and future
incentives for these vehicles in a transparent manner.
3. Gasoline-Ethanol Flexible-Fuel Vehicles
The impact of ethanol flexible fuel vehicles (FFVs) is easy to determine because we calculate
fleet average GHG values both with and without the incentives in order to ensure that no
manufacturer exceeds the maximum allowable value of the incentive. Under the GHG program,
EPA allows FFV credits intended to correspond to the amounts allowed in the CAFE program
under the statutory provisions, but only for the 2012 to 2015 model years. As with the CAFE
program, the GHG program bases FFV credits on the assumption that FFVs operate 50% of the
time on the alternative fuel and 50% of the time on conventional fuel, resulting in CO2 emissions
that are based on an arithmetic average of alternative fuel and conventional fuel CO2 emissions.
The CO2 emissions measurement on the alternative fuel is multiplied by a 0.15 factor. The 0.15
factor is used because, under the CAFE program's implementing statutes, a gallon of alternative
fuel is deemed to contain 0.15 gallons of gasoline fuel. Again, this approach is only applicable
for the 2012-2015 model years of the GHG program.
For example, for a flexible-fuel vehicle that emits 330 g/mi CO2 while operating on E85 and 350
g/mi CO2 while operating on gasoline, the resulting CO2 level to be used in the manufacturer's
fleet average calculation would be:
[(330 x 0.15) + 350]
C02 = 		^		 =199.8 g/mi
EPA realizes that by temporarily using the CAFE-based approach—including the 0.15 factor—
the CO2 emissions value for the vehicle is calculated to be significantly lower than it actually
would be otherwise, even if the vehicle were assumed to operate on the alternative fuel at all
times. This represents the short-term "incentive" being provided to FFVs. Under the GHG
program, FFV credits are available only through the 2015 model year; starting in model year
2016, GHG compliance values are based on actual emissions performance of the FFV on
conventional and alternative fuels, weighted by EPA's assessment of the actual use of these fuels
in FFVs.31 In fact, the standards in the early years of the GHG program were developed with an
explicit understanding that some manufacturers would make use of this and other incentive and
credit programs to meet the standards.
In the 2015 model year the dual-fuel credit limit in the CAFE program is 1.0 mpg across a
manufacturer's separate car and truck fleets (dedicated alternative fuel vehicles and vehicles that
use electricity are not subject to this limit on credits). In other words, FFVs may not increase a
31 EPA Guidance Letter "E85 Flexible Fuel Vehicle Weighting Factor for Model Year 2016-2018 Vehicles," CD-
14-18, November 12, 2014.
25

-------
manufacturer's average fuel economy for its car or truck fleets by more than 1.0 mpg. To parallel
the CAFE limitations, the GHG program contains a similar credit limit, but calculated in terms of
CO2 based on each manufacturer's unique fleet average performance. EPA chose this approach
because of the non-linearity between mpg and CO2 emissions. For example, a 1.0 mpg increase
from a base of 15 mpg represents a CO2 decrease of about 37 g/mi, while a 1.0 mpg increase
from a base of 30 mpg represents a CO2 decrease of about 10 g/ mi. Thus, the CO2 reduction that
manufacturers may get from the FFV credits for a given fleet is limited to the CO2 value
comparable to 1.0 mpg and is calculated from a manufacturer's specific fleet average
performance value.
Eight manufacturers produced FFVs in the 2015 model year, as shown below in Tables 3-5 and
3-6. Clearly, FCA, Ford, and GM produced the overwhelming majority of vehicles capable of
operating on E85. While almost 20 percent of model year 2014 vehicles were FFVs, this dropped
to about 10 percent in the 2015 model year. Note that the number of models shown in Table 3-5
is based on EPA's "model type" designation (used for EPA Fuel Economy and Environment
Labels), and is not equivalent to "nameplate." Generally speaking, a model type is a unique
combination of a nameplate (e.g., Silverado), an engine (e.g., 6 cylinder), a drive system (e.g., 4
wheel drive), and a transmission (e.g., 6-speed automatic). Thus, a single nameplate that is
offered with two engines, in both two- and four-wheel drive, and in manual and automatic
transmissions, will result in eight different model types. For example, the four Nissan truck
models shown in Table 3-5 are made up of two- and four-wheel drive versions of two
nameplates, the Titan and the Armada.
Most of these manufacturers focused their FFV production in the truck segment, with trucks
making up 70 percent of all FFV production in the 2015 model year. With the exception of FCA,
all of these manufacturers reduced FFV production in the 2015 model year, bringing almost one
million fewer FFVs to market relative to the previous model year, or an overall decrease of about
34 percent. FCA increased their FFV production by about 40,000 vehicles; making more than
one third of their 2015 model year vehicles capable of using E85.

Table 3-7 shows the impact of FFVs on each manufacturer's fleet for the 2012-2015 model
years. FCA, Ford, GM, and Jaguar Land Rover all maximized the FFV credit in both car and
truck fleets in the 2015 model year. In other words, these manufacturers produced at least
27

-------
enough FFVs to claim the maximum FFV benefit. The overall impact of FFVs on the fleet as a
whole decreased by one third, from 9 g/mi in model year 2014 to 2015 to 6 g/mi in model year
2015.

D. Credits Based on Air Conditioning Systems
The vast majority of new cars and light trucks in the United States are equipped with air
conditioning (A/C) systems. There are two mechanisms by which A/C systems contribute to the
emissions of greenhouse gases: through leakage of hydrofluorocarbon refrigerants into the
atmosphere (sometimes called "direct emissions") and through the consumption of fuel to
provide mechanical power to the A/C system (sometimes called "indirect emissions"). The high
global warming potential (GWP) of the current predominant automotive refrigerant, HFC-134a,
means that leakage of a small amount of refrigerant will have a far greater impact on global
warming than emissions of a similar amount of CO2. The impacts of refrigerant leakage can be
reduced significantly by systems that incorporate leak-tight components, or, ultimately, by using
a refrigerant with a lower global warming potential. The A/C system also contributes to
increased tailpipe CO2 emissions through the additional work required by the engine to operate
the compressor, fans, and blowers. This additional power demand is ultimately met by using
additional fuel, which is converted into CO2 by the engine during combustion and exhausted
through the tailpipe. These emissions can be reduced by increasing the overall efficiency of an
A/C system, thus reducing the additional load on the engine from A/C operation, which in turn
means a reduction in fuel consumption and a commensurate reduction in GHG emissions.
Manufacturers may generate and use credits for improved A/C systems in complying with the
CO2 fleet average standards in the 2012 and later model years (or otherwise to be able to bank or
trade the credits). These provisions were also used in the 2009-2011 model years to generate
early credits, prior to the 2012 model year. Seventeen manufacturers used the A/C credit
provisions - either for leakage reductions, efficiency improvements, or both - as part of their
compliance demonstration in the 2015 model year.
28

-------
The A/C provisions are structured as additional and optional credits, unlike the CO2 standards for
which manufacturers must demonstrate compliance using the EPA exhaust emission test
procedures. The EPA compliance tests do not measure either A/C refrigerant leakage or the
increase in tailpipe CO2 emissions attributable to the additional engine load of A/C systems.
Because it is optional to include A/C-related GHG emission reductions as an input to a
manufacturer's compliance demonstration, the A/C provisions are viewed as an additional
program that credits manufacturers for implementing A/C technologies that result in real-world
reductions in GHG emissions. A summary of the A/C credits reported by the industry for all
model years, including the early credit program years, is shown in Table 3-8 (note that because
not all manufacturers participated in the early credits program, credit volumes and percentages
from 2009-2011 and 2012-2015 are not comparable). Table 3-9 shows the total air conditioning
credits (combined leakage and efficiency credits, in Megagrams) reported by each manufacturer
in the 2015 model year, and the grams per mile impact across their entire vehicle fleet. Like the
TLAAS program and alternative fuel vehicle incentives, EPA's standards are predicated in part
upon manufacturers earning credits for reducing GHG emissions from A/C systems. Table 3-10
shows the benefit of A/C credits, translated from Megagrams to grams per mile, for each
manufacturer's fleet for the 2012-2015 model years. Note that despite excluding Volkswagen
from many tables for reasons described in Section 1, they are included in this section because
A/C efficiency and leakage credits are not related to the issues impacted by the ongoing
investigation.

1. Air Conditioning Leakage Credits
A manufacturer choosing to generate A/C leakage credits with a specific A/C system is required
to calculate a leakage "score" for the A/C system.32 This score is based on the number,
performance, and technology of the components, fittings, seals, and hoses of the A/C system.33
This score, which is determined in grams per year, is calculated using the procedures specified
by the SAE Surface Vehicle Standard J2727. The score is subsequently converted to a grams per
mile credit value based on the global warming potential (GWP) of the refrigerant, for
consistency with the units of GHG exhaust emissions. The grams per mile value is used to
calculate the total tons of credits attributable to an A/C system by accounting for the VMT of the
vehicle class (car or truck) and the production volume of the vehicles employing that A/C
system.
In the 2012 model year, all leakage credits were based on improvements to the A/C system
components, e.g., to O-rings, seals, valves, and fittings, as no manufacturer had yet introduced a
new low-GWP refrigerant in the U.S. In the 2013 model year, General Motors and Honda
introduced vehicles that further reduced the impacts of A/C system leakage by using HFO-
1234yf, a relatively new low-GWP refrigerant. These two manufacturers were the first to
introduce this refrigerant in U.S. vehicle models (the Cadillac XTS and the Honda Fit EV). HFO-
1234yf has an extremely low GWP of 4, as compared to a GWP of 1430 for HFC-134a, the
refrigerant currently used throughout most of the industry. The use of HFO-1234yf expanded
considerably in the 2014 model year, from two manufacturers and 42,384 vehicles in the 2013
model year, to five manufacturers and 628,347 vehicles in the 2014 model year. Although Honda
dropped the Fit EV in model year 2015 and GM sales of models using HFO-1234yf declined,
both FCA and Jaguar Land Rover increased their offerings of vehicles using HFO-1234yf,
contributing to a tripling of the number of vehicles using this refrigerant in the 2015 model year.
FCA more than tripled the volume of vehicles using the new refrigerant, to the point where more
than 75 percent of 2015 model year FCA vehicles are using it. Industry-wide, more than ten
percent of 2015 model year vehicles are using HFO-1234yf, with FCA accounting for more than
95 percent of those. Jaguar Land Rover continues to have the greatest penetration within their
fleet, using HFO-1234yf in almost 90 percent of vehicles produced in the 2015 model year. The
net impact on credits is that these manufacturers collectively generated about 3 million more
Megagrams of A/C leakage credits than they would have generated by using HFC-134a. FCA
accounts for most of these credits, accumulating almost 2.9 million Megagrams more than they
would have using HFC-134a. Table 3-11 shows the production volume of models using HFO-
1234yf for the 2012-2015 model years, by manufacturer.
32	See 40 CFR 86.1867-12.
33	The global wanning potential (GWP) represents how much a given mass of a chemical contributes to global
wanning over a given time period compared to the same mass of carbon dioxide. Carbon dioxide's GWP is defined
as 1.0.

2. Air Conditioning Efficiency Credits
Manufacturers that make improvements in their AJC systems to increase efficiency, thus
reducing CO2 emissions due to AJC system operation, may be eligible for AJC efficiency credits.
Most of the additional load on the engine from AJC systems comes from the compressor, which
pressurizes the refrigerant and pumps it around the system loop. A significant additional load on
the engine may also come from electric or hydraulic fans, which are used to move air across the
condenser, and from the electric blower, which is used to move air across the evaporator and into
the cabin. Manufacturers have several technological options for improving efficiency, including
more efficient compressors, fans, and motors, and system controls that avoid over-chilling the air
(and subsequently re-heating it to provide the desired air temperature with an associated loss of
efficiency). For vehicles equipped with automatic climate-control systems, real-time adjustment
of several aspects of the overall system (such as engaging the full capacity of the cooling system
only when it is needed, and maximizing the use of recirculated air) can result in improved
efficiency. The regulations provide manufacturers with a "menu" of technologies and associated
credit values (in grams per mile of CO2). Credits are capped at 5.7 g/mi for all vehicles in the
2012-2016 model years, and at 5.0 and 7.2 g/mi for cars and trucks, respectively, in the 2017 and
later model years. The total tons of credits are then based on the total volume of vehicles in a
model year using these technologies.
Fifteen manufacturers used the provisions that allow credits based on improvements to the
overall efficiency of the AJC system, as shown in Table 3-14. These manufacturers reported a
total of more than 12 million Mg of CO2 AJC efficiency credits in the 2015 model year,
accounting for about 3 g/mi across the 2015 fleet. Table 3-15 shows the efficiency credits in
grams per mile for the 2012-2015 model years.

E. Credits Based on "Off-Cycle" Technology
"Off-cycle" emission reductions can be achieved by employing technologies that result in real-
world benefits, but where that benefit is not adequately captured on the test procedures used by
manufacturers to demonstrate compliance with emission standards. EPA's light-duty vehicle
greenhouse gas program acknowledges these benefits by giving automobile manufacturers three
pathways by which a manufacturer may accrue off-cycle CO2 credits. The first is a
predetermined list or "menu" of credit values for specific off-cycle technologies that may be
used beginning in model year 2014.34 This pathway allows manufacturers to use conservative
credit values established by EPA for a wide range of off-cycle technologies, with minimal data
submittal or testing requirements. This pathway was widely used in the 2015 model year. In
cases where additional laboratory testing can demonstrate emission benefits, a second pathway
allows manufacturers to use a broader array of emission tests (known as "5-cycle" testing
because the methodology uses five different testing procedures) to demonstrate and justify off-
cycle CO2 credits.35 The additional emission tests allow emission benefits to be demonstrated
over some elements of real-world driving not captured by the GHG compliance tests, including
high speeds, rapid accelerations, and cold temperatures. Credits determined according to this
methodology do not undergo additional public review. GM is currently the only manufacturer to
have used this pathway in the 2012-2015 model years. The third and last pathway allows
manufacturers to seek EPA approval to use an alternative methodology for determining the off-
cycle technology CO2 credits.36 This option is only available if the benefit of the technology
cannot be adequately demonstrated using the 5-cycle methodology. Manufacturers may also use
this option for model years prior to 2014 to demonstrate off-cycle CO2 reductions for off-cycle
technologies that are on the menu, or to demonstrate reductions that exceed those available via
use of the menu. Several manufacturers have petitioned for and been granted credits using this
pathway.37
Table 3-16 shows the total off-cycle technology credits reported by manufacturers in the 2015
model year and the grams per mile impact on their respective fleets. Clearly the technologies
involved are currently implemented to varying degrees across manufacturers, accounting for
anywhere from zero g/mi (the manufacturers not shown in Table 3-16) to 6.1 g/mi for FCA. Off-
cycle credits from these 12 manufacturers accounted for a benefit of 3 g/mi across the entire
2015 model year fleet.
Table 3-17 shows the off-cycle credits in grams per mile for the 2012-2015 model years.
Although GM did generate off-cycle credits in the 2012 and 2013 model years, the grams per
mile equivalent of those credits rounds to 0.0, as shown, as is also the case for Subaru in model
year 2014.

Federal Register notices, and the EPA decision documents. See https://www.epa.gov/veliicle-and-engine-

1. Off-Cycle Credits Based on the Menu
Starting with 2014 models, manufacturers have an option for generating GHG credits, in the
form of "default" credit values specified in the regulations (a "menu" of technologies with credit
values, or the calculation method for such values, clearly defined) for certain off-cycle
technologies installed on vehicles. More than 95 percent of 2015 off-cycle credits were generated
via this pathway, and for all but GM it was the sole pathway used to generate off-cycle credits.
The impact of credits from this pathway on a manufacturer's fleet is capped at 10 g/mi, meaning
that any single vehicle might accumulate more than 10 g/mi, but the cumulative effect on a
single manufacturer's fleet may not exceed a credit, or reduction, of more than 10 g/mi.
Table 3-18 shows the total off-cycle credits based on the menu pathway reported by
manufacturers in the 2015 model year and the grams per mile impact on their respective fleets.

Tables 3-19 and 3-20 provide details regarding the specific off-cycle technologies, including
how many credits were reported for each technology, and the implementation rate of each off-
cycle technology by manufacturers. Several of these technologies are "thermal control
technologies" in that they reduce the demand on the AJC system by venting hot air, by moving
heat away from passengers, or by reducing cabin heating from the sun. Due to expected
synergistic effects of the thermal technologies, the credits from the group of thermal control
technologies are capped at 3.0 g/mi for cars and 4.3 g/mi for trucks. The per-vehicle grams per
mile credit varies between cars and trucks; for example, the credit available for active seat
ventilation is 1 g/mi for cars and 1.3 g/mi for trucks. The regulations clearly define each
41

-------
technology and any requirements that apply for the technology to generate credits. The
definitions may be summarized as follows:
•	Active aerodynamics - These technologies are automatically activated to improve the
aerodynamics of a vehicle under certain conditions. These include grill shutters, which
allow air to flow around the vehicle more efficiently, and suspension systems that
improve air flow at higher speeds by reducing the height of the vehicle. Credits are
variable and based on the measured improvement in the coefficient of drag, a test metric
that reflects the efficiency of airflow around a vehicle.
•	Thermal control technologies - These systems reduce the air temperature of the vehicle
interior, lowering GHG tailpipe emissions by reducing the fuel demand on the A/C
system. Thermal control technologies are subject to a per-vehicle cap on credits of 3.0
g/mi for cars and 4.3 g/mi for trucks.
o Active and passive cabin ventilation -Active systems use mechanical means to
vent the interior, while passive systems rely on ventilation through convective air
flow. Credits range from 1.7 to 2.8 g/mi.
o Active seat ventilation - These systems move air through the seating surface,
transferring heat away from the vehicle occupants. Credits are 1.0 g/mi for cars
and 1.3 g/mi for trucks,
o Glass or glazing - Credits are available for glass or glazing technologies that
reduce the total solar transmittance through the glass, thus reducing the heat from
the sun that reaches the occupants. The credits are calculated based on the
measured solar transmittance through the glass and on the total area of glass on
the vehicle.
o Solar reflective surface coating - Credits are available for solar reflective surface
coating (e.g., paint) that reflects at least 65 percent of the infrared solar energy.
Credits are 0.4 g/mi for cars and 0.5 g/mi for trucks.
•	Active engine and transmission warmup - These systems use heat from the vehicle that
would typically be wasted (exhaust heat, for example) to warm up key elements of the
engine, allowing a faster transition to warm operation. A warmed up engine and/or
transmission consumes less fuel and emits less tailpipe CO2. Systems that use a single
heat-exchanging loop that serves both transmission and engine warmup functions are
eligible for either engine or transmission warmup credits, but not both.
o Active engine warmup - Uses waste heat from the engine to warm up the engine.
Credits are 1.5 g/mi for cars and 3.2 g/mi for trucks,
o Active transmission warmup - Uses waste heat from the engine to warm up the
transmission. Credits are 1.5 g/mi for cars and 3.2 g/mi for trucks.
•	Engine idle stop-start - These systems allow the engine to turn off when the vehicle is at
a stop (e.g., at a stoplight), automatically restarting the engine when the driver releases
the brake and/or applies pressure to the accelerator. If equipped with a switch to disable
the system, EPA must determine that the predominant operating mode of the system is
the "on" setting (defaulting to "on" every time the key is turned on is one basis for such
a determination). Thus some vehicles with these systems are not eligible for credits.
Credits range from 1.5 to 4.4 g/mi, and depend on whether the system is equipped with
an additional technology that allows heat, when demanded, to continue to be circulated
to the vehicle occupants when the engine is off during a stop-start event.
42

-------
•	Hish efficiency exterior lights - These lights reduce the total electric demand, and thus
the fuel consumption and GHG emissions, of the lighting system in comparison to
conventional lighting technologies. Credits are based on the specific lighting locations,
ranging from 0.06 g/mi for turn signals and parking lights to 0.38 g/mi for low beams.
The total of all lighting credits may not exceed 1.0 g/mi.
•	Solar panels - Vehicles that use batteries for propulsion, such as electric, plug-in hybrid
electric, and hybrid vehicles may receive credits for solar panels that are used to charge
the battery directly or to provide power directly to essential vehicle systems (e.g.,
heating and cooling systems). Credits are based on the rated power of the solar panels.

*Credits are not always reported by manufacturers in a format that shows the total credits for each technology as
we show here. For the purposes of this report we have used the data from manufacturers to calculate the credits
shown in this table.
Table 3-20 shows the percent of each manufacturers' production volume using each of the
"menu" technologies, i.e., the penetration rate of a given technology within a manufacturer's
fleet. The totals of the manufacturer rows are not provided, as they would sum to more than
43

-------
100% and are not meaningful values, reflecting only that some vehicles are equipped with
multiple off-cycle technologies. The data is not currently collected in a format across all
manufacturers that allows a determination of how many vehicles have at least one off-cycle
technology or how many technologies are on a given vehicle, thus the total would only indicate
how many individual technologies were used to generate credits. However, the implementation
rates are still useful and reveal some interesting things. For example, there was significant
penetration of glass or glazing technology across these manufacturers, with more than half of
them reporting installing this technology on more than 50 percent of their vehicles, and four
manufacturers approaching a 100 percent implementation rate (FCA, GM, Jaguar Land Rover,
and Kia). High efficiency lighting is another technology with high penetration across a number
of manufacturers, with seven manufacturers reporting implementation on at least half of their
fleet, and Jaguar Land Rover and BMW at or near 100 percent. Traditionally the domain of
hybrid gas-electric vehicles, engine idle stop-start is making inroads across conventional
vehicles, to a significant degree with some manufacturers. With 98 percent implementation,
Jaguar Land Rover had the highest proportion of vehicles equipped with engine idle stop-start.
The most "popular" technologies across the manufacturers were high efficiency lights and active
seat ventilation, both of which were employed by at least 10 manufacturers, followed by engine
idle stop-start, which was used by 9 manufacturers. Although active seat ventilation was used by
many manufacturers, it remains a technology with limited offering, appearing on only about ten
percent of the 2015 model year fleet, with Jaguar Land Rover appearing the outlier with
implementation on more than 50 percent of their vehicles (this is consistent with this technology
being largely limited to luxury brands or models). The most widely used technologies across the
fleet were glass or glazing, appearing on 8.7 million vehicles (more than half of the 2015 fleet),
and high efficiency lighting, which was installed on 8.2 million vehicles, or about 50 percent of
the fleet. FCA was the leader in terms of the number of technologies used to generate off-cycle
credits, gaining GHG reductions from ten unique technologies implemented at varying rates
across their fleets. FCA used every menu technology except active cabin ventilation and solar
panels.
Table 3-21 shows the grams per mile benefit that each manufacturer accrued from each off-cycle
technology. Like the preceding table, this demonstrates the mix of technologies being used
across the manufacturers and the extent to which each technology benefits each manufacturer's
fleet. BMW, FCA, Ford, and Jaguar Land Rover can be singled out as the manufacturers
reporting the greatest benefits from off-cycle technologies, from 4.2 to 6.1 g/mi, while the
remaining manufacturers achieved between 1 and 3 g/mi. A closer look shows different
strategies across these manufacturers of varying sizes and product lines. FCA and Ford achieved
the benefits of 6.1 and 5.6 g/mi, respectively, largely through their reported use of passive cabin
ventilation, glass or glazing, and active engine warmup systems, with the remainder coming from
other technologies. BMW was the only manufacturer using active cabin ventilation, with a 91
percent implementation rate and accounting for half of their 4.2 g/mi total off-cycle credits.
BMW was also the leader in penetration of active engine warmup systems, which accounted for
1.5 g/mi, and runner-up in the use of high-efficiency lighting, bringing them another 0.6 g/mi.
Jaguar Land Rover, which, as noted earlier, has made very large GHG reductions across their
fleet since the start of the program, gained more than half of their 4.9 g/mi of off-cycle credits
through adoption of stop-start systems across the vast majority of their product line. No other
manufacturer has approached this penetration rate.

2. Off-Cycle Technology Credits Based on 5-Cycle Testing
As was the case in the 2012-2014 model years, GM is the only manufacturer to have requested
and been granted off-cycle credits based on 5-cycle testing. These credits are for an off-cycle
technology used on certain GM gasoline-electric hybrid vehicles. The technology is an auxiliary
electric pump, which keeps engine coolant circulating in cold weather while the vehicle is
stopped and the engine is off. GM received off-cycle credits in the early credits program for
hybrid full size pick-up trucks that were equipped with this technology. In the 2012 model year,
the technology was expanded to include two Buick hybrid passenger car models. In the 2013
model year the technology was applied to GM's full-size hybrid trucks as well as the Buick
LaCrosse, Buick Regal, and Chevrolet Malibu models equipped with GM's "eAssist" technology
(about 2,000 trucks and 45,000 cars). The 2014 model year GM vehicles receiving this credit
were the eAssist-equipped Buick LaCrosse, Buick Regal, Chevrolet Malibu, and Chevrolet
Impala, totaling almost 160,000 vehicles. In the 2015 model year, the eAssist-equipped vehicles
were the Buick LaCrosse, Buick Regal, and Chevrolet Malibu. These vehicles feature engine
stop-start capability for improved fuel economy, and as a result the engine can frequently be
turned off when the vehicle is stopped, such as at a traffic light, resulting in real-world fuel
savings. However, during cold weather, a hybrid vehicle without the auxiliary heater pump
would need to keep the engine idling during the stop periods solely to maintain coolant flow to
the heater to maintain a comfortable temperature inside the vehicle. This would reduce the fuel
economy benefits of the stop-start feature during cold weather, which is an "off-cycle"
temperature condition not captured by the greenhouse gas compliance test methods. The off-
cycle credits reported by GM in the 2009-2015 model years are shown in Table 3-22. The
calculated grams per mile benefit rounds to zero because of the low volume of these credits, thus
the table does not display these credits in equivalent grams per mile.

3. Off-Cycle Technology Credits Based on an Alternative Methodology
This third pathway for off-cycle technology credits allows manufacturers to seek EPA approval
to use an alternative methodology for determining the off-cycle technology CO2 credits.38 This
38 See 40 CFR 86.1869-12(d).
47

-------
option is only available if the benefit of the technology cannot be adequately demonstrated using
the 5-cycle methodology. Manufacturers may also use this option for model years prior to 2014
to demonstrate off-cycle CO2 reductions for off-cycle technologies that are on the menu, or to
demonstrate reductions that exceed those available via use of the menu. The regulations require
that EPA seek public comment on and publish each manufacturer's application for credits sought
using this pathway. Several manufacturers have petitioned for and been granted credits using this
pathway.39
In the fall of 2013, Mercedes requested off-cycle credits for the following off-cycle technologies
in use or planned for implementation in the 2012-2016 model years: stop-start systems, high-
efficiency lighting, infrared glass glazing, and active seat ventilation. EPA approved
methodologies for Mercedes to determine these off-cycle credits in September of 2014.40
Subsequently, FCA, Ford, and GM requested off-cycle credits under this pathway. FCA and
Ford submitted applications for off-cycle credits from high efficiency exterior lighting, solar
reflective glass/glazing, solar reflective paint, and active seat ventilation. Ford's application also
demonstrated off-cycle benefits from active aerodynamic improvements (grill shutters), active
transmission warm-up, active engine warm-up technologies, and engine idle stop-start. GM's
application described the real-world benefits of an AJC compressor made by Denso with variable
crankcase suction valve technology. EPA approved the credits for FCA, Ford, and GM in
September of 2015.41 FCA reported 2,599,923 Megagrams of off-cycle credits to EPA for the
2009-2013 model years, and the totals for those model years have been revised and reflected in
this report where appropriate. In the 2015 model year, GM reported earning 348,102 Mg of
credits from the Denso A/C compressor.
More recently, EPA published a notice in the Federal Register on September 2, 2016, requesting
comments on methodologies for off-cycle credits submitted by BMW, Ford, GM, and
Volkswagen.42 The comment period closed on October 3, 2016, and as of the writing of this
report, EPA is evaluating comments and drafting a decision document. If approved, these credits
would appear in a future edition of this report to the extent that manufacturers claim them.
F. Deficits Based on Methane and Nitrous Oxide Standards
EPA finalized emission standards for methane (CH4) and nitrous oxide (N2O) emissions as part
of the rule setting the 2012-2016 model year GHG standards. The standards that were set in that
rulemaking were 0.010 g/mi for N2O and 0.030 g/mi for CH4. These standards were established
to cap emissions of GHGs, given that current levels of CH4 and N2O are generally significantly
below these established standards. These capping standards were intended to prevent future
39 EPA maintains a web page on which we publish the manufacturers' applications for these credits, the relevant
Federal Register notices, and the EPA decision documents. See https://www.epa.gov/veliicle-and-engine-
certification/compliance-information-light-duty-greenhouse-gas-ghg-standards.

increases in emissions of these GHGs, and were generally not expected to result in the
application of new technologies or significant costs for manufacturers using current designs.
There are three different ways for a manufacturer to demonstrate compliance with these
standards. First, and used by most manufacturers, manufacturers may demonstrate compliance
with these standards with test data as they do for all other non-GHG emission standards. Because
there are no credits or deficits involved with this approach, and there are no consequences with
respect to the CO2 fleet average calculation, the manufacturers are not required to submit this
data as part of their GHG reporting and hence this GHG compliance report does not include
information from manufacturers using this option. Second, EPA also allows an alternative CO2-
equivalent standard option, which manufacturers may choose in lieu of complying with the cap
standards. This C02-equivalent standard option allows manufacturers to include CH4 and N2O,
on a C02-equivalent basis, in their CO2 emissions fleet average compliance level. This is done
without adjusting the fleet average CO2 standard to account for the addition of CH4 and N2O
emissions. Manufacturers that choose this option are required to include the CH4 and N2O
emissions of all their vehicles for the purpose of calculating their fleet average. In other words,
the value of CREE (the carbon-related exhaust emissions, as described earlier) for these
manufacturers will include CO2, hydrocarbons, and carbon monoxide, as well as CH4 and N2O
emissions (which are adjusted to account for their higher global warming potential than CO2), for
all their vehicles. Analyses of emissions data have shown that use of this option may add
approximately 3 g/mi to a manufacturer's fleet average. Two manufacturers chose to use this
approach in the 2015 model year: Mazda, and Subaru.
The third option for complying with the CH4 and N2O standards was initially limited to the 2012-
2014 model years, but was subsequently expanded to include all model years of the program.
Under this approach, manufacturers can essentially define an alternative, less stringent CH4
and/or N2O standard for any vehicle that may have difficulty meeting the specific standards. This
alternative standard is treated as any other emission standard in that it must be met for the full
useful life of the vehicle. This method provides some additional flexibility relative to the other
two options in that (1) a manufacturer can target specific vehicles for alternative standards
without incurring a fleet-wide impact, and (2) CH4 and N2O are delinked, in that a manufacturer
can meet the default regulatory standard for one and select an alternative standard for the other.
However, the key aspect of this approach is that manufacturers that use it must calculate a deficit
(in Megagrams) based on the less stringent standards and on the production volumes of the
vehicles to which those standards apply. Seven manufacturers made use of the flexibility offered
by this approach in the 2015 model year, as shown in Table 3-23. Like any other deficit, these
deficits must ultimately be offset by CO2 credits. While these deficits could be carried forward to
the next three model years like other deficits, all of the manufacturers using this approach were
able to cover these incremental deficits with credits, either carried forward from 2010-2014 or
generated in 2015.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the initial compliance data,
Volkswagen had car deficits of 321 and 82,288 Mg for CH4 and N20, respectively, and truck deficits of 811 and 9,662 Mg for
CH4 and N20, respectively, for a total of 93,022 Mg and a fleet impact of 0.8 g/mi. Should the investigation and corrective
actions yield different C02 data, the revised data will be used in future reports.
Tables 3-24 and 3-25 show the grams per mile equivalent CH4 and N2O deficits for the 2012-
2015 model years. As in all of the tables in this document, the final Fleet Total row indicates the
impact across the entire fleet, including manufacturers and vehicles that did not participate in the
alternative CH4 and/orN20 standards.

G. 2015 Model Year Compliance Values
As described at the outset of this section, there are a number of "building blocks" that are
assembled to describe a manufacturer's performance in a given model year. These elements
cumulatively make up a manufacturer's "compliance value," i.e., the performance value specific
to a given model year and fleet that is compared to an emissions standard (or target) to determine
whether a fleet generates a net credit or deficit balance in that model year. Table 3-26
summarizes all of these building blocks (described in previous sections) for the 2015 model year
fleet for each manufacturer. The values in Table 3-26 are calculated for each manufacturer's
combined car and truck fleet by weighting car and truck values according to the relative
production volumes and VMT of cars and trucks.43 The final row shows values for the total 2015
fleet. Note that the compliance value for each manufacturer can be derived from the values in the
table by applying the credits and deficits to the 2-cycle tailpipe value. For example, Ford's 2-
cycle tailpipe emissions of 311 g/mi is reduced by applying FFV, A/C, and off-cycle credits
totaling 28 g/mi, yielding a final compliance value of 284 g/mi (any apparent mathematical
differences are the result of rounding). Tables 3-27 and 3-28 show the same information for car
and truck fleets, respectively.44 The resulting compliance values can then be compared to the
target values for each fleet to determine whether a manufacturer will report credits or deficits in
the 2015 model year. Again, these values are not regulatory values, but are calculated from the
Megagrams of credits reported by the manufacturers to EPA and presented this way to more
easily communicate compliance in understandable metrics.
43	The compliance and target values do not represent official regulatory values. Regulatory target values are
determined separately for car and truck fleets. The compliance value is not a regulatory value, but rather is a
calculated value based on each manufacturers' unique car and truck sales weighting for a given model year, and is
shown as a way of portraying the cumulative impact of a manufacturer's tailpipe performance and any optional
credits used by a manufacturer.
44	Versions of Tables 3-19, 3-20, and 3-21 for the 2012-2014 model years are shown in Appendix C.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the initial compliance
data, Volkswagen has a 2-cycle tailpipe value of 269 g/mi, an FFV credit of 8 g/mi, an A/C credit of 9 g/mi, a CH4
and N20 deficit of 1 g/mi, and a compliance value of 252 g/mi. Should the investigation and corrective actions
yield different C02 data, the revised data will be used in future reports.
45 Tesla manufactures only electric vehicles. As explained in section 3.C. 1, a temporary incentive for electric
vehicles allows electric vehicle tailpipe emissions to be set equal to zero grams/mile, as shown in this table. An
artifact of this is that Tesla's compliance value is represented by a negative grams/mile value after applying air
conditioning credits.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the initial compliance
data, Volkswagen has a light truck 2-cycle tailpipe value of 336 g/mi, an FFV credit of 13 g/mi, an A/C credit of

Table 3-29 shows the calculated compliance values for each manufacturer's car and truck fleet
for the 2012-2015 model years. As can be seen in the table, the decreases in manufacturer
compliance values from 2014 to 2015 outweighed the increases, leading to a net decrease of 7
g/mi across the fleet of combined cars and trucks.

H. 2015 Model Year Footprint-Based CO2 Standards
The final values needed to determine the relative performance for a manufacturer in a model year
are the emissions standards that apply to each manufacturer's fleets in that model year. At the
end of each model year, manufacturers calculate unique CO2 standards for each fleet (cars and
trucks) using equations specified in the regulations based on the footprint of their vehicles.46 The
footprint "curves" for the 2012-2015 model years are shown in Figure 3-1. The unique CO2
standard for each manufacturer's fleet is a production-weighted average of the CO2 target values
determined from the curves based on all of the unique footprint values for the vehicles in a
manufacturer's fleet. Trends in the overall average footprint value are thus important because of
the direct impact on the stringency of the GHG standards.

The calculated CO2 standards for the 2012-2015 model years are shown in Table 3-30.
Manufacturers use these unique footprint-based car and truck standards - which are required by
regulation - to determine their compliance status. A third value for each manufacturer - a sales-

it can be simply viewed as the area of the rectangle enclosed by the four points where the tires touch the ground.

and VMT-weighted standard for the combined car and truck fleet - is provided for convenience
and comparative purposes, but it is not a compliance value required by the regulations. Similar to
the compliance values described in the previous section, the decreases in the manufacturers' CO2
standards from 2014 to 2015 outweighed the increases, resulting in an increase in the overall
stringency of the program of about 13 g/mi.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the initial compliance data, in the 2015 model year Volkswagen had C02 standards of
236, 297, and 249 g/mi for cars, trucks, and all vehicles, respectively. Should the investigation and corrective actions yield different C02 data, the revised data will be used in
future reports.
*Some or all vehicles subject to temporary less stringent TLAAS standards. See section 3.B.
59

-------
Overall, the standards decreased by 13 g/mi from 2014 to 2015, an increase in stringency driven
by the more stringent target curves for the 2015 model year. This increase in stringency in a
single model year is greater than the total stringency increases in all previous model years
combined. However, the target curves represent only one of several key factors that influence the
standards. While increased stringency overall from one year to the next is expected because of
the structure of the target curves, there are other contributing factors that can result in - and
explain - occasional exceptions that may occur. For example, Table 3-30 shows that the standard
for Volvo trucks increased - got less stringent - from 2014 to 2015. This is because Volvo put
some vehicles in the less stringent TLAAS standards in model year 2015 (the only year in which
they have done so), and the net impact is a decrease in stringency. Volvo did not increase their
overall footprint and nor did they sell more trucks, either of which could increase their GHG
standard. In fact, their car footprint stayed about the same as in 2014, their truck footprint
decreased by almost a full square foot, and their truck sales were down relative to cars from the
2014 model year.
The average footprint for the overall fleet decreased in the 2015 model year by 0.3 square feet, to
49.4 square feet. The average car footprint remained unchanged at 46.1 square feet, and the truck
footprint decreased by 1.1 square feet to 53.9 square feet, the smallest truck footprint since the
GHG standards took effect. Of the 17 manufacturers shown in Table 3-31, fleet average footprint
increased for seven, decreased for nine, and was unchanged for one. Increases in footprint ranged
from 0.3 square feet (Mazda) to 1.0 square foot (Hyundai). Note that a change in the overall fleet
footprint does not necessarily indicate that manufacturers built smaller or larger vehicles;
because the footprint is weighted by production volume, shifts in volumes can result in a change
to an overall fleet footprint. Thus, a change in footprint could be a result of either of these factors
independently, or more likely, a mix of both factors.

I. Overall Compliance Summary
Final compliance for the 2012-2015 model years is summarized in Table 3-32 for the overall
model year fleet, and separately for cars and trucks in Tables 3-33 and 3-34, respectively. As in
the tables in Section 3.G, these show how the 2-cycle tailpipe values and the credits are used to
"build" the overall compliance value, which is then compared to the model year standards
described in Section 3.H. The tables also show, in the final column, the value achieved by
subtracting the compliance value from the standard, which, for the 2012-2015 model years, is a
positive value, thus indicating over-compliance with the standards. Overall, manufacturers
outperformed the 2015 standard by 7 g/mi.47 In both the 2012 and 2013 model years, the
industry's over-compliance was almost entirely driven by the compliance margin seen in the car
fleet, since the truck compliance values essentially equaled the overall fleet standards. This was
not true for the 2014 model year, where the truck fleet achieved a compliance margin relative to
the truck standard of 8 g/mi, thus contributing to the overall fleet compliance margin. In the 2015
model year the bulk of the over-compliance can again be attributed to passenger cars, although
the trucks remained in compliance with their applicable fleet standard of 312 g/mi, and some
manufacturers (Jaguar Land Rover, Subaru) over-complied in their truck fleet with a greater
margin than in their car fleet.

*Values stated in this table and in the text are correct, although rounding of values may result in some
apparent differences.
A comparison between compliance values and standards for each manufacturer and fleet is
shown in Table 3-35. The final row shows values for the total 2015 fleet. The comparison of the
compliance and standards in Table 3-35, shown in the "Net Compliance" columns, indicates
whether a manufacturer generated net credits or deficits in the 2015 model year. Negative values
indicate over-compliance with the standards, or compliance values that are lower than the
standard by the stated value. Positive values are thus an indication of compliance values that
exceed (i.e., do not meet) the applicable standards. Kia, for example, generated a 2015 model
year deficit because their overall compliance value of 259 g/mi is above their fleet-wide standard
of 247 g/mi. Ford, on the other hand, reported net credits based on a compliance value of 284
g/mi, 8 g/mi lower than their fleet-wide standard of 292 g/mi. Note, however, that the generation
of a net deficit in the 2015 model year by any manufacturer does not necessarily indicate that the
manufacturer has failed to comply with the 2015 model year standards. Kia, for example, will
offset their 2015 deficit by using credits generated in previous model years, thereby complying
with the 2015 standards.48 The final row of Table 3-35 shows the conclusion that manufacturers
over-complied with the 2015 model year standards by 7 g/mi. A comparison of the values in the
three previous tables to EPA projections for these values is in Appendix A.49
48	This section deals only with manufacturer performance within a model year, and does not consider the
implications on compliance of the use of credits or deficits from previous model years or of sold and purchased
credits. See Section 5 for a discussion of the current compliance status of each manufacturer that considers all of
these factors.
49	EPA projections are from the previously-referenced rulemakings from May 7, 2010 and October 15, 2012.

4. Credit Transactions
Credits may be traded among manufacturers with a great deal of flexibility (with the exception of
2009 model year credits and credits generated by manufacturers using the TLAAS program,
which are restricted to use only within a manufacturer's own fleets). There are only a few
regulatory requirements that relate to credit transactions between manufacturers (other than the
restrictions just noted), and these are generally designed to protect those involved in these
transactions. While it may seem obvious, it is worth stating that a manufacturer may not trade
credits that it does not have. Credits that are available for trade are only those available (1) at the
conclusion of a model year when all the data is available with which to calculate the number of
credits generated by a manufacturer, and not before; and (2) after a manufacturer has offset any
deficits they might have. Credit transactions that result in a negative credit balance for the selling
manufacturer are not allowed and can result in severe punitive actions. Although a third party
may facilitate transactions, EPA's regulations allow only the automobile manufacturers to
engage in credit transactions and hold credits.
Since the 1990's, many of EPA's vehicle emissions regulatory programs have included the
flexibilities of averaging, banking, and trading (ABT). The incorporation of ABT provisions in
EPA emissions regulations has been generally supported by a wide range of stakeholders: by
manufacturers for the increased flexibility that ABT offers and by environmental groups because
ABT enhances EPA's ability to introduce standards of greater stringency in an earlier time frame
than might otherwise be achieved. Historically, manufacturers tended to make use of the ability
to average emissions and bank emissions credits for use in subsequent years, but until recently
there has been almost no credit trading activity between companies. The use of trading
provisions in EPA's light-duty GHG program is a historic development, and one that EPA
welcomes because we believe it will allow greater GHG reductions, lower compliance costs, and
greater consumer choice.
The credit transactions reported by manufacturers through the 2015 model year are shown in
Table 4-1.50 As of the close of the 2015 model year, almost 19 million Megagrams of CO2
credits had changed hands, almost doubling since publication of the 2014 model year report.
BMW and GM were new entrants in the buyer's market, and Coda both entered the credit
seller's market and abandoned the automotive manufacturing business, selling their remaining
credits while under Chapter 11 bankruptcy. Credit distributions are shown as negative values, in
that a disbursement represents a deduction of credits of the specified model year for the selling
manufacturer. Credit acquisitions are indicated as positive values because acquiring credits
represents an increase in credits for the purchasing manufacturer. The model year represents the
"vintage" of the credits that were sold, i.e., the model year from which the credits originated. The
vintage always travels with the credits, regardless of when a transaction takes place and in what
model year the credits are ultimately used. A manufacturer with 2010 model year credits can
hold them until 2021, meaning, for example, that a sale of 2010 credits could potentially be
511 Manufacturers do not report transactions to EPA as they occur. Thus there may be additional credit transactions
that have occurred that are not reported here, but because of the timing of those transactions (after the manufacturers
submitted their 2014 model year data) those transactions will be reported in the 2015 model year reports of the
manufacturers involved, and thus will be included in EPA's performance report regarding the 2015 model year.

reported to EPA as late as the reporting deadline for the 2021 model year, and those 2010 credits
traded in MY 2021 could be used by the buyer to offset deficits from the 2018-2021 model years.
The overall impact of these credit transactions on the compliance position of each manufacturer
is discussed in Section 5, which pulls together all the credits and deficits, including early credits,
discussed in the preceding sections. Note that each value in the table is simply an indication of
the quantity of credits from a given model year that has been acquired or disbursed by a
manufacturer, and thus may represent multiple transactions with multiple buyers or sellers.

5. Compliance Status After the 2015 Model Year
Based on the information reported to EPA, the vast majority of manufacturers have successfully
demonstrated compliance with the 2012-2015 model year standards and are carrying a positive
credit balance into the 2016 model year. The manufacturers that report compliance with all
model years represent more than 99 percent of all cars and light trucks produced for U.S. sale in
these first three model years of EPA's GHG standards. Table 5-1 shows one view of the
accumulated credits for each manufacturer. Each manufacturer reporting a positive balance in the
final column is, by definition, in compliance with the 2012-2015 model years (because all
deficits must be offset before carrying credits forward).
Table 5-1 shows the total credits (or deficits) for each manufacturer in the last column. Table 5-1
also shows the credits (or deficits) generated by each manufacturer in the 2009-2015 model
years, as well as the net impact of credit transactions on each manufacturer's credit balance.
However, to fully understand the current compliance position of each manufacturer, we also
need to know the makeup of the credit balance in terms of the origin, or vintage, of the credits.
Knowing the vintage is important both for credits and deficits, because we need to know when
credits expire and must be forfeited, and we need to know when a manufacturer is in violation of
the regulations as a result of failing to offset a deficit within the required time frame.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the initial compliance data, Volkswagen earned a deficit of 385,236 Mg of in model
year 2015 and will carry 5,517,054 Mg into model year 2016. Should the investigation and corrective actions yield different C02 data, the revised data will be used in future
reports.

-------
Because manufacturers accumulate car and truck credits separately, and because they are
allowed to move credits around between cars and trucks, the situation can get far more complex
than seen in the Ferrari example.51 Consider this example, where a manufacturer generates 1500
Mg of car credits and a -500 Mg deficit in trucks in 2012, and where credits all have a 5-year
lifespan:
2012 Credits
Fleet	(Mg)
Cars	1500
Trucks	-500
Total	1000
The manufacturer must use the car credits to offset the truck deficit in this case, because there are
no credits available from prior model years to use, and credits cannot be carried forward until
deficits are addressed. Thus the manufacturer carries a balance of 1000 Mg of credits from 2012
into 2013. Then in this example let's assume that in 2013 they generate 1000 Mg of credits in the
car fleet and a deficit of -1000 Mg in the truck fleet, as shown below:
Here, the manufacturer
would have 1000 Mg of
2012 credits
2012 Credits 2013 Credits
Fleet	(Mg)	(Mg)
Cars	1500	1000
Trucks	-500 	-1000
Total (1000)	0
There are multiple choices for a manufacturer faced with such a situation. As shown above, all
deficits are adequately addressed within each model year, and a manufacturer could leave it at
that. Doing so would mean carrying forward the 1000 Mg of credits remaining from 2012 into
2014. There is, however, a smarter - but not mandatory - option. Because the regulations allow
car and truck credits and deficits to be managed as separate "bins," and because newer credits are
generally more valuable than older credits (because they last longer) it would be smarter for this
manufacturer to use the 1000 Mg of credits from 2012 to offset the deficit of -1000 Mg in the
2013 truck fleet, as shown below:
Here, the
manufacturer would
have 1000 Mg of 2013
2012 Credits 2013 Credits
Fleet	(Mg)	
Cars	1500
Trucks	-500	
Total	1000	1000
The bottom line remains the same (1000 Mg of credits are carried into 2014), except that in this
case the credits carried forward have a vintage from the newer 2013 model year. Theoretically, a
manufacturer could use any mix of 2012 and 2013 credits to offset the 2013 truck deficit, in
which case the credits remaining to carry forward would be a mix of 2012 and 2013 credits. The
value of a given vintage is based on its expiration date, and the expiration date of 2010-2016
51 Note that the regulations require that all credits and deficits within a vehicle class (passenger cars or light trucks)
be aggregated before transfers between vehicle classes may occur. See 40 CFR 86.1865-12(k)(5).

model year credits in EPA's GHG program is fixed at the 2021 model year, meaning that for the
2010-2016 model years it is less important to treat credits in this way. Nevertheless, this "first in,
first out" accounting method is being used to determine the makeup of credit balances held by
manufacturers (unless a manufacturer expresses a preference for an alternative accounting). It is
challenging to display all the credit transfers, transactions, and vintages in a single data table in
an easily understandable manner. However, we can display the current state of each
manufacturer and the vintage of all the credits currently held by each manufacturer.
Table 5-2 reveals the credit balances for each manufacturer, after adjusting for credit transactions
and transfers, by the vintage of the credits reported by the manufacturer. The model year column
headings represent the vintages that make up the total credits (or deficit) being carried forward
into the 2016 model year. This table shows, for example, the extent to which some manufacturers
have used credits from prior model years. Volvo, for example, reported generating about 730,000
early credits (see Table 2-1). They have used all the 2009 and 2010 credits and most of the 2011
credits to offset deficits in the 2012-2014 model years, and thus carried a positive balance into
the 2015 model year, to which they added some credits reported from the 2015 model year. A
deficit may be carried forward for three years after the year in which it is generated, meaning that
deficits from the 2013 model year must be reconciled by the end of the 2016 model year.
Note that Tables 5-1 and 5-2 over-simplify the data with respect to the manufacturers using the
TLAAS program in order to present the data concisely. In model year 2015, Jaguar Land Rover
and Mercedes have vehicles subject to the primary standards and subject to the less stringent
TLAAS standards, yet for the purpose of these tables we have aggregated the credits
accumulated in both the primary and TLAAS fleets into a single row in the table. Although they
are not separated for the purposes of these tables, EPA maintains careful records (as do the
manufacturers) of the credits within the Primary and TLAAS programs, as is necessary because
of the different treatment and restrictions for the different fleets. The data we are making
available online and in this report will identify the source of each credit (e.g., whether from the
Primary or TLAAS fleets).

Appendix A: Comparing Actual Performance to
Rulemaking Projections
As described in Section 1, EPA's GHG program was promulgated in two regulatory actions
conducted jointly with NHTSA. The first rulemaking established standards for the 2012-2016
model years, and the second rulemaking set standards for the 2017 and later model years.52 53 In
each of these rulemakings we included tables summarizing our projections of what the fleet-wide
standards would be and how we expected manufacturers would comply with the standards. When
evaluating these projections and how they compare to the actual performance as described in this
report, consider that the projections for the 2012-2016 model years were finalized in early 2010,
and the 2017 and later projections were determined in the middle of 2012. The projections were
made with the best available information at the time, but it should not be surprising that actual
performance differs from the rulemaking projections. Factors such as consumer preferences,
technology innovation, fuel prices, and manufacturer behavior can change in unanticipated ways,
leading current, actual performance to diverge from projections made in the past. While a
comparison of actual performance to projections is interesting, and helps illuminate whether or
not the program is achieving its expected benefits, this is secondary in the context of this report,
which is focused on actual compliance. Compliance of manufacturers with EPA's standards is
not determined by comparing current model year results to past projections, but is instead
determined by comparing achieved compliance values to the regulatory footprint-based standards
covered in Sections 1-5 of this report.
Table A-l shows key projected values for the combined car and truck fleet for the 2012-2025
model years. All of the values in this table (and Tables A-2 and A-3) come directly from the
regulatory actions noted above. Note that we projected that the industry, on average, would
comply exactly with the target, i.e., the compliance value equals the target value in each model
year. This table illustrates a fundamental principle: EPA projections from the rulemaking
analysis assumed manufacturers would achieve significant GHG emission reductions (and hence
compliance) through a variety of technologies. In the early years, until the incentive is phased
out in the 2016 model year, we projected significant production of flexible fuel vehicles (FFV).
We also projected relatively high production of reduced GHG AJC systems across the fleet,
resulting in reductions ranging from 3.5 g/mi in 2012 and increasing to over 20 g/mi late in the
program. As shown in Table A-l, we projected that manufacturers would start with a 2-cycle
tailpipe value of 277 g/mi in the 2015 model year, reducing that by total credits and incentives of
about 14 g/mi, thus yielding a net compliance value of 263 g/mi. We did not make any
estimations of the use of N2O and CH4 alternative standards for two reasons: (1) the overall
impact was expected to be very small, and (2) manufacturers are required to offset deficits
accumulated with C02-equivalent credits as a result of using this flexibility, thus there is no net
impact on the program.

Tables A-2 and A-3 show the same projected values as Table A-l, but separately for cars and
trucks, respectively. In the regulatory action establishing the standards we did not publish car-
and truck-specific estimated values for the 2-cycle tailpipe emissions or the use of credits and
incentives in the 2012-2015 model years, thus these values are shown as N/A in these tables.

Table A-4 shows a comparison of the projected values (in Tables A-l, A-2, and A-3) with the
actual performance for the 2012-2015 model years for the combined car and truck fleet. As is the
case throughout this report, values for the combined fleet of cars and trucks are calculated as a
weighted average of the individual car and truck fleet values. However, the methodology used
for weighting and combining car and truck values in this section differs from the methodology
used elsewhere in this report. As noted in Chapter 1, the general methodology used in this report
to create a complete fleet value from separate car and truck fleet values incorporates weighting
by the relative lifetime vehicle miles traveled (VMT) of cars and trucks (lifetime VMT values for
cars and trucks are specified in the regulations as 195,264 and 225,865 miles, respectively).
Because credits are calculated based on differing car and truck VMT values, the methodology for
combining car and truck grams per mile values must include weighting by VMT for the result to
be internally and mathematically consistent with the total Megagrams of credits generated by the
fleet. However, past rulemaking projections for the combined car and truck fleet were
determined by weighting car and truck fleet values by their relative production only, ignoring the
impact of VMT. In order to provide an accurate comparison, the actual performance values in
Table A-4 are calculated in the same manner as the projected values: without weighting by
VMT. For this reason the actual values in Table A-4 are not the same as values with the same
labels presented elsewhere in this report. For example, the 2012 model year 2-cycle tailpipe
value in Table A-4 is 299 g/mi, whereas the same metric is shown as 302 g/mi in Table 3-1. Both
of these values are correct, as the former is not VMT-weighted and the latter is VMT-weighted.
It is only within this section that a different methodology is used, specifically to facilitate an
apples-to-apples comparison between actual fleet performance and EPA's projections. Note that
values for the car and truck fleets are identical to those shown elsewhere in the report; only the
values for the combined fleet will differ based on the different methods of calculating combined
values from the individual car and truck values.
Table A-4 shows that actual industry-wide compliance targets for the combined car and truck
fleets are slightly higher than EPA's projections for both model year 2012 (by 1 g/mi) and model
year 2013 (by 3 g/mi). This gap grew further in the 2014 and 2015 model years, to 8 and then 9
g/mi, because industry-wide footprint values and the truck fraction of the fleet are higher than
projected in the rulemaking analyses (for more information on footprint trends, see EPA's CO2
and Fuel Economy Trends report at epa.gov/otaq/fetrends.htm).
More important, however, is that despite these higher targets, actual industry-wide overall
compliance values have been consistently lower than projected in the EPA rulemaking analyses
for the first three years of the program, and in 2015 the actual compliance value was essentially
the same as projected for model year 2015. Actual industry-wide 2-cycle tailpipe emissions
performance was 8-9 g/mi lower than the projected values in the 2012 and 2013 model years,
and equal to the projected value in the 2014 model year. However, in the 2015 model year, 2-
cycle emissions exceeded our projections by 5 g/mi. In model year 2015, flexible fuel and off-
cycle credits were higher than projected, while AJC credits were slightly lower than projected.
Most important, based on these 2-cycle emissions values, it is apparent that the cumulative
impact of the first four years of the program is that aggregate CO2 emissions reductions have
been slightly larger than projected by EPA, i.e., the lower-than-projected values in model years
2012 and 2013 more than offset the higher-than-projected value in model year 2015.
76

-------
Tables A-5 and A-6 provide comparative data separately for cars and trucks for the 2012-2015
model years (though projected values for use of credits by vehicle category are not available
until model year 2016). For cars, the directional impacts are similar to those for the combined car
and truck fleet, i.e., the actual targets are higher than projected and the actual compliance values
are lower (6 g/mi in 2015). The actual targets were also higher than the projected targets for the
truck fleet until the 2015 model year, when the actual fleet value equals the projected value. For
trucks, however, actual compliance values were slightly higher than projected for the first two
years, but have slightly outperformed the projected values in model years 2014 and 2015.

Note: Volkswagen is not included in this table due to an ongoing investigation. Based on the original compliance
data, Volkswagen has a 2-cycle tailpipe value of 281 g/mi, an FFV credit of 1 g/mi, an A/C credit of 7 g/mi, a CH4
and N20 deficit of 2 g/mi, and a compliance value of 276 g/mi. Should the investigation and corrective actions
yield different C02 data, the revised data will be used in future reports.
