Getting Started

1. Tool Overview

This User's Guide accompanies and explains the Local Greenhouse Gas Inventory Tool: Community
Module. The tool was developed to support communities across the United States to evaluate the
greenhouse gas emissions. Understanding these emission levels provides a base year for tracking
emission trends, developing mitigation strategies and policies, and assessing progress towards
meeting goals.

The tool helps users to develop a base year community greenhouse gas inventory, following the
Global Protocol for Community-Scale GHG Emissions (GPC). This is a companion tool to the Local
Government Operations Module, and any totals estimated in the Local Government Operations
Module should be included in the Industrial/Commercial sector in the Community GHG Inventory
tool.

2. Getting Started

The Community Module was developed using Microsoft® Excel 2007 and 2010. The tool will only
operate properly using Excel 2007 or later. Before using the tool, ensure your computer meets the

Introduction

Community Greenhouse Gas Inventory Tool

What is the Community Greenhouse Gas Inventory Tool?

Local Climate and Energy Program

Thistool is designed to help cities evaluate and estimategreenhouse gas emissions within their communities. Thistool can help cities understand
their greenhouse gas emissions profile and the sectors driving emissions, provides a baseline fortracking emission trends, and can feed into an
action plan that will address and reduce emissions.

The tool helps users to develop a baseline greenhouse gas inventory for communities, accordingto the Global Protocol for Community-Scale GHG
Emissions ( GPC), version 0.9.

Use of default data:

Thistool gives users the option of applyingtheir own locality-specificdata or in some cases using pre-loaded default data. The default data are
gathered by federal agencies and other sources covering the default emission factors and system assumptions needed to calculate emissions
accordingto the GPC.

important Terminology:

Scope- A common means of categorizing direct and indirect emissions to improve transparency and for identifying differenttypes of climate policies
and goals. There are three scopes of emissions:

The Security Warning lets the user know that some active content from the spreadsheet has been
disabled, meaning that Excel has prevented the macros in the spreadsheet from functioning. Since
the Community Module needs macros in order to function properly, the user must enable macros.
To do so in Excel 2010, simply click the "Enable Content" button in the security message (Figure 1).
To do so in Excel 2007, click the "Options" button in the security message and then select, "Enable
this content" in the pop-up box (Figure 2). Enabling the macro content for the tool in these ways
only enables macros temporarily in Excel but does not change the macro security settings.

wide activity data to data by facility or meter. The more specific the data provided by the user,
however, the more accurate and useful the tool will be. See Box 1 for details.

The GHG inventory segment of the tool proceeds through nine main sectors of community-scale
emissions. These sectors and the type of data the user needs to provide are show in

Table 1. Gray cells indicate if a default value is available for that input or if the input is optional.

In general, this tool is pre-programmed with default emission factors and system assumptions
needed to calculate emissions from the Global Protocol for Community-Scale GHG Emissions, and
the LGOP. Default emission factors are generally provided from national or state publications, and
provide a relatively accurate estimate of emissions. If local, or site-specific factors are available for
your locality, those should be used to overwrite the default factors. Wherever possible in the
inventory process, default values are used. The tool provides users the option to use default data or
to override default values if they have city-specific information.

Throughout the tool, cells are shaded yellow where the user is required to enter data.

Box 1. GHG Inventory Data Input Options

Option A: "Quick" Inventory

•	Enter city-wide fuel, electricity, and water consumption data by sector.

•	This method takes less time, but does not allow the tool to as effectively calculate emission
levels.

Option B: Comprehensive Inventory

•	Enter fuel, electricity, water consumption by facility, by sector.

•	This method requires more time and data availability from the user, but provides the most
accurate GHG inventory.

Tool Layout

There are two main sections of this tool: Background Data Collection, and Emissions Calculations. In
each, the user will enter data to configure the tool to their specific community and receive
customized results.

Background Controls

On the Inventory Control Sheet, identify the city, and the inventory year for the inventory. The
sectors in the Community Module have already been determined and follow in line with the sectors
provided in the Global Protocol for Community-Scale GHG Emissions. The sectors used in the tool
set up the tool to reflect organizational units for which the most common data are available at the
community level.

The user will also set up information about their electricity providers. Users can select which eGRID
sub-region serves the area, view the default emission factors, and can enter up to five utilities with
utility-specific emission factors (if available).

GHG Emission Scopes

To account for direct and indirect emissions, and to provide transparency and a guiding framework
for the inventory tool, GHG estimates are categorized according to 3 scopes. The following scopes
are defined by the Global Protocol for Community-Scale GHG Emissions and are used throughout
the tool:

Scope 1: All direct GHG emission sources from activities taking place within the community's
geopolitical boundary.

Scope 2: Energy-related indirect emissions that result as a consequence of consumption of grid-
supplied electricity, heating and/or cooling, within the community's geopolitical boundary.

Scope 3: All other indirect emissions not covered in Scope 2, such as emissions resulting from the
extraction and production of purchased materials and fuels, outsourced activities, waste disposal,
etc.

In addition to accounting for emissions according to these 3 scopes, the GPC provides guidance on
imports and exports by a community, and how emissions for these should be taken into account. As
an example in the GPC (on pg. 86), waste imported into the city is reported as Scope 1 emission
estimates. Waste generated by the city and exported and treated outside of the city's boundaries is
included in Scope 3 estimates. The Community GHG Inventory Tool accounts for in-boundary
consumption and resulting emissions and excludes any emissions released from products consumed
or services exported from the locality.

The following graphic highlights sources of emissions that might be applicable to your community.

Since Scope 3 emissions vary in complexity and in the activities they represent, it is recommended that
users calculate emission estimates for additional sources outside the tool and enter the estimates in the
Additional Emission Sources worksheet. An example of Scope 3 calculations from one local government
is included in the box below.

Lakewood Colorado 2007 GHG Inventory Report Scope 3 Emissions

Lakewood included Scope 3 emissions in the Materials and Waste Sector for cement use (per
capita), water and wastewater fugitive emissions, fuel production, food production, and municipal
solid waste (MSW). Examples for cement use and food production are included below.

•	For cement use, Lakewood established total cement use for the state from a Colorado
Economic report. The city then determined per capita cement use by using the total
expenditure of cement products in Colorado by the cost of cement per kilogram. The
kilograms of cement attributed to the Lakewood population were calculated by taking the
proportion of Lakewood population to the total Colorado population. The cement emission
factor was taken from the National Renewable Energy Laboratory's (NREL) Life Cycle
Inventory Database.

•	Lakewood calculated the embodied energy from food and food packaging by first collecting
information on food expenditures on a per-household basis from the Consumer
Expenditure Survey. The city then estimated emissions by applying an emission factor (kg
C02e/$ food consumed) from a Carnegie Mellon University Green Design Institute report.

Inventory Calculations

After the user has configured the tool on the Control Sheet, the tool will calculate the community
emissions, or the base year greenhouse gas inventory for the community. The inventory is separated

U.S. Environmental Protection Agency

into the 9 main emission sources below, from the Local Government Operations Protocol (LGOP),
and these sources are further organized by scope. Users can also enter emissions for any additional
sources they would like to calculate outside of the tool, and enter the estimates in the Additional
Emission Sources worksheet.

1. Stationary Combustion of Fossil Fuels (Scope 1)

2. Building/Facility Electricity Consumption (Scope 2)

3. Mobile Combustion of Fossil Fuels (Fleet) (Scope 1)

4. Solid Waste Disposal (Scope 1)

5. Wastewater Treatment (Scope 1)

6. Water Consumption (Scope 3)

7. Agriculture & Land Management (Scope 3)

8. Urban Forestry (Scope 3)

9. Waste Generation (Scope 3)

10. Additional Emission Sources (optional) (Scopel, 2, or 3)

For each source, the user will be asked to enter data about relevant community activities (e.g.
electricity consumed, fuel used) during the inventory base year. The tool can be used to develop
emissions estimates for a base year, as well as used to track emissions over time if different versions
of the Excel file are saved. Default emission factors for each activity are provided, and the user is
given the option to override these factors, if necessary. There are multiple sheets for some emission
sources, but not for all sources. Each emissions source follows a distinct process the user will follow
to determine the emissions, as explained below:

Stationary Combustion, Electricity Use, and Mobile Combustion

1. Users enter activity/fuel use data on Entry Sheet OR

2. Users can batch import data on Data Sheet.

3. Emissions are calculated and summarized on the Calculation Sheet.

Solid Waste

1. Users answer questions about their city's solid waste disposal system on the Control Sheet.

2. Based on the answers to the questions, users will enter data about their solid waste system and
view emissions summary on the Entry, Calculation & Summary Sheet.

Wastewater Treatment

1. Users answer questions about their city's wastewater treatment system(s) on the Control Sheet.

2. Based on the answers to the questions, users will enter data about their wastewater treatment
systems on the Entry Sheet; and

3. Emissions will be calculated and summarized on the Calculation & Summary Sheet.

Biogenic emissions are not included in the tool, and as a standard practice the C02 emissions
occurring from biofuel combustion are not included in total inventory estimates. According to the
U.S. Environmental Protection Agency, biogenic C02 emissions are defined as C02 emissions related
to the natural carbon cycle, as well as those resulting from the combustion, harvest, combustion,
digestion, fermentation, decomposition, or processing of biologically based materials. EPA provides
examples of biogenic C02 emissions including:

• C02 from the combustion of biogas collected from biological decomposition of waste in
landfills, wastewater treatment, or manure management processes

• C02 from combustion of the biological fraction of municipal solid waste or biosolids

• C02 derived from combustion of biological material, including forest-derived and
agriculture-derived feedstocks.

According to the LGOP, because of the distinction between biogenic and anthropogenic emissions, if
you choose to quantify biogenic emissions, they should be tracked separately from Scope 1 direct
emissions. In addition, the LGOP advises the following:

"Biogenic emissions related to forestry and land management should not be quantified under

this Protocol as the Protocol is designed to account primarily for the anthropogenic sources of

Local Greenhouse Gas Inventory Tool: Community Module 13

GHG emissions, and is not designed to assess the carbon stocks of government-owned lands
(see Section 2.3 in the LGOP). Biogenic emissions also occur from sources other than
combustion, such as the aerobic decomposition of organic matter. These non-combustion
biogenic emissions should not be included in your GHG inventory."

Emission factors for each calculation are included in the "Factors" worksheet of the tool, and
specific sources for each of the emission factors are provided in the table below.

Recent discussion surrounding community-wide inventories has focused on the distinction between
activities and sources. Unlike the sources and scopes discussed above, activities are defined as the use
of energy, materials, and/or services by members of the community that result in the creation of GHG
emissions either directly or indirectly (ICLEI 2013). Sources are defined as any physical process inside the
jurisdictional boundary that releases GHG emissions into the atmosphere. According to ICLEI's U.S.
Community Protocol, "drawing a distinction between the two can help local governments to
conceptualize, organize, and report on emissions associated with their communities." In addition, ICLEI's
Protocol states that distinguishing between sources and activities "can help local governments decide
how to group the emissions numbers they might gather for the purpose of reporting. For example, a
purely source-based emissions inventory could be summed to estimate total emissions released within
the community's jurisdictional boundary. In contrast, a purely activity-based emissions inventory could
provide perspective on the efficiency of the community, even when the associated emissions occur
outside the jurisdictional boundary." While some communities have calculated emissions for both, for
simplicity, the Community GHG Inventory Tool accounts for sources of GHG emissions. Additional
information on activities and scopes can be found in ICLEI's protocol, section 1.3. The table below
provides details on how some of the activities prevalent in many communities relate to sectors and
scopes.

3. Sheet Instructions and Methodology

This section provides a guide to using the Community Module to estimate greenhouse gas emissions
from the community. The methods and default values used for the inventory component of this tool
are from the Global Protocol for Community-Scale GHG Emissions and the LGOP. Calculation sheets
are provided so that methods and emission estimates are transparent in the tool. Instructions for
completing each sheet of the tool are below.

Local Greenhouse Gas Inventory Tool: Community Module 16

-------
U.S. Environmental Protection Agency

Control Sheet

Use the Control Sheet to configure the tool to your community. The sectors for your community are
already established as residential, commercial/institutional, industrial, and energy generation. Next
identify city electricity providers, and click the "Set Up" button (in Step 4 at the bottom of the
Control Sheet) to get started.

The tool can be used to inventory GHG emissions from 2000 through 2020. EPA decided not to
include inventory years going back to 1990, as there is limited availability of emission factors dating
back to 1990 and communities will likely not have data going back to 1990. According to the LGOP,
"It is good practice to compile an emissions inventory for the earliest year for which complete and
accurate data can be gathered. The base year for the UNFCCC and subsequent Kyoto Protocol is
calendar year 1990. However, required data from 1990 is often prohibitively difficult or impossible
to collect. Given that the priority for a greenhouse gas management program should be on practical
results, it is more important that the base year be documented with enough detail to provide a good
basis for local action planning than it is that all local governments produce an inventory with the
same, stipulated base year."

Stationary Combustion and Electricity Consumption

receive a confirmation message when the record has been successfully added. At any point, you
may click "Reset Form" to clear all fields. If you would like to enter more than one record at a time,
you may proceed to the "Stationary-Data" or "Electricity-Data" sheet and directly add data there.

If you would like to change any aspect of a previous entry, select "Edit Record." A drop-down menu
will appear. Select the entry you would like to change, make changes to the entry fields as needed,
and then click "Add/Update Record." To delete a record entirely, click the "Delete Record" button. A
dropdown menu will appear that contains the previously entered data. Select the entry to delete
from the drop-down, and confirm that this entry should be deleted. After you confirm that you
would like the entry deleted, the saved data will be erased.

If you enter data at the facility level, please specify the type of facility from the dropdown menu

Solid Waste Inventory Sheets

Control Sheet

On the control sheet, first select whether your community has operational control over any landfills.
If not, you may opt to use the U.S. Environmental Protection Agency's (EPA) Waste Reduction Model
(WARM) to calculate your Scope 3 emissions. This step is optional, but can also be used to calculate
waste emission reductions.

For every landfill that you have operational control over, please select whether those landfills have
landfill gas collection systems and whether those systems are comprehensive or partial. Under the
LGOP, landfill gas (LFG) collection systems are considered "comprehensive" if the landfill is required
to have a LFG collection system under EPA's New Source Performance Standards or a system more
stringent as dictated by local regulations.

For these landfills that do not have LFG collection systems, you need to use the California Air
Resources Board's (CARB) Landfill Emissions Tool, which is based on the IPCC First Order Decay
(FOD) model. To use the model, you will need the annual waste deposited in each landfill as well as
the opening and closing year of each landfill. Once you have run the model, please paste the final
methane (CH4) emissions output for each landfill in the yellow cells in the tool.

Calculations Sheet

Depending on your entries on the Solid Waste control sheet, you will be presented with formulas to
calculate your city's emissions from solid waste management. Enter values requested in the pale

yellow cells. Click on the checkbox to use default values for the fraction of CH4 in your city's landfill
gas, if applicable. Your solid waste emissions will be summarized at the bottom of the sheet.

Wastewater Treatment Inventory Sheets
Control Sheet

On the wastewater control sheet, answer the series of questions about the type(s) of wastewater
treatment systems in your community. For every type of system (anaerobic or aerobic treatment
with or without nitrification/denitrification), you will be asked to provide the population served by
that system on the entry sheet. You will also answer questions about data availability for your
wastewater treatment systems.

Entry Sheet

The wastewater entry sheet provides data input cells based on your answers to the questions on the
wastewater control sheet. Data in the yellow cells in the specified units is requested.

Calculations Sheet

The calculation sheet shows the formulas used to determine your city's emissions from wastewater
treatment, using the methodology from the Local Government Operations Protocol. The gray cells
link to the values you entered on the Wastewater Entry Sheet.

Your total emissions are summarized in the table at the top of the sheet. You may scroll down to
view the detailed calculations, but no action is required on this sheet. If you would like to change
any of the entered values, you may do so on the entry sheet.

Imported Water Inventory Sheet

The water sheet is where you will calculate the Scope 3 emissions associated with imported water
consumption by your community. These emissions are indirectly associated with electricity use and
other emissions required to provide water to your city. This does not include the electricity or
energy use used directly at city water facilities. Any such electricity use associated with water within
your city (such as city water pumps) should be included in the Electricity tab.

If your city imports water, enter the amount of water consumed by sector during the inventory year
and where that water is imported from. Each import source is associated with different emission
factors, and will be used to calculate your city's indirect emissions from water consumption.

Agriculture & Land Management Inventory Sheet

The agriculture & land management sheet is where you will calculate the Scope 3 emissions
associated with fertilizer application by the different sectors in your community. These emissions
are associated with the application of synthetic, organic, and manure fertilizers. A portion of applied
fertilizers volatilize into the air in the form of N20.

Local Greenhouse Gas Inventory Tool: Community Module 21

May 2015

-------
U.S. Environmental Protection Agency

Once you enter the information for each sector on the amount of fertilizer applied by fertilizer type,
the total emissions from this source will be calculated.

Urban Forestry Inventory Sheet

The urban forestry sheet is where you will calculate the Scope 3 emissions associated with urban
trees managed by your community. Changes in carbon stocks in urban trees are calculated by
estimating the total urban area, the percent of that urban area with tree cover, and applying a
carbon storage factor to estimate carbon sequestration from urban trees. Note the GPC states that
biogenic forestry emissions can be reported separately from totals (see pg. 39 in the GPC). EPA
decided to include these estimates in the tool so that communities could optionally estimate carbon
stocks if this was applicable.

Once you enter the information on the urban tree coverage for each sector, the total carbon
sequestration from this source will be calculated.

Waste Generation Inventory Sheet

The waste generation sheet is where you will calculate the Scope 3 emissions associated with the
decomposition of waste generated within your borders by the community, but landfilled elsewhere.
This sheet applies to waste produced directly or indirectly by community activities and disposed of
in a solid waste facility not operated by the community. To calculate Scope 3 emissions from waste,
utilize EPA's WAste Reduction Model (WARM) either as a web-based calculator or an Excel
spreadsheet. If the waste is disposed of in a facility operated by the community, emissions should be
calculated as Scope 1 emissions on the Solid Waste-Control and Solid Waste-Entry sheets.

Once you enter the information for each sector on the waste generation, the total emissions from
this source will be calculated.

Additional Sources Inventory Sheet

Use this sheet to enter emissions from any additional sources you would like to include in your
inventory. Assign each source to a sector, note what scope the emissions fall under, and enter any
greenhouse gas emissions in metric tons of carbon dioxide equivalent (MTC02e). The GPC provides a
list of additional sources in Table 4.3 that could be estimated outside of the tool, and the results of
the emissions calculations can be input on this sheet.

4. Uncertainty

The GHG inventory component of the tool follows the methodology of the GPC. Users should refer
to the GPC for a discussion of the uncertainty associated with default assumptions.
