F-GHG Emissions Reduction Efforts:
2018 Supplier Profiles
U.S. Environmental Protection Agency
Office of Air and Radiation
March 2020
The Supplier Profiles outlined in this document detail the efforts of large-area flat panel suppliers to reduce
their fluorinated greenhouse gas (F-GHG) emissions in manufacturing facilities that make today's large-area
panels used for products such as TVs and computer monitors. More comprehensive information on how F-
GHGs are used in flat panel display (FPD) manufacturing is available on the Center for Corporate Climate
Leadership's website at: https://www.epa.gov/climateleadership/center-corporate-climate-leadership-sector-
spotlight-electronics.
Summary of Supplier Profiles
The table below on page six summarizes which panel suppliers publicly report their F-GHG emissions, their
most recent F-GHG emissions, and, where available, their F-GHG emissions intensity based on panel
production. It also includes information on suppliers' broader GHG emission reduction goals, since F-GHGs
comprise a significant portion of on-site Scope 1 GHG emissions,1 as well as the regulatory and/or voluntary
efforts by which suppliers are reducing their F-GHG emissions.
Most importantly, the table highlights which suppliers have fully implemented F-GHG emissions reduction
measures across their older and newer manufacturing, or fabrication, facilities, also referred to as 'fabs.' For
panel suppliers that have not fully implemented F-GHG reduction measures, whereby approximately 90
percent of annual F-GHG emissions are avoided or removed, further opportunities for improvement exist.
The summary table and charts below reflect data, assembled from public sources and the suppliers
themselves, on F-GHG emissions for calendar year or fiscal year 2018, depending on the supplier's reporting
cycle. Public sources of information include suppliers' responses to the annual CDP Investor Questionnaire and
each supplier's annual sustainability or corporate social responsibility reports.
Following the summary information, individual profiles provide more information on specific methods, such as
abatement, process optimization and use of alternatives that suppliers are using to reduce their F-GHG
emissions.
1 Scope 1 GHG emissions are an organization's direct emissions from sources that are owned or controlled by that
organization.

Key Findings Based on 2018 Data
•	Six global LCD suppliers, representing 68% of LCDs manufactured in 2018, reported their annual F-GHG
emissions and/or reduction efforts. Suppliers AOU, Innolux, and Sharp have consistently reported on
their F-GHG emissions since 2012 and LG Display has reported publicly again for the second consecutive
year. As 8 years of data demonstrate (Previous Supplier Profiles), key suppliers have been maintaining
and/or improving F-GHG reductions over time. Additionally, the 2018 profiles see the first public
reporting of F-GHG emissions for BOE, whose market share has increased substantially over the last
five years, also pointing to improved transparency in regional LCD manufacturing.
•	Some suppliers who previously reported annual F-GHG emissions did not provide their F-GHG
emissions for their 2018 calendar year reports. While some liquid crystal display (LCD) suppliers have
reported, and continue to report, their F-GHG emissions publicly, others with large and/or increasing
market share opt to report their F-GHG emissions either privately or directly to their customers. Thus,
greater transparency is still needed on all LCD panel suppliers' F-GHG emissions to better understand
overall trends in F-GHG emissions. An improved understanding is needed on the extent to which F-GHG
emission reductions result from both the use of F-GHG reduction technologies and the use of lower
GWP F-GHGs in key processes. This will better equip brands to understand all methods their
4ln 2012, Samsung (18% market share in 2012) and LGD (26% market share in 2012) reported their F-GHG emissions
which contributes to	mai"ket share of reporters. In 2013, LGD continued to reported emissions in. In 2014-2016
LGD did not report their F-GHG emissions which caused the decline in publicly reported F-GHG emissions. In 2017, LGD
resumed reporting their F-GHG emissions, resulting in an increase in publicly reported F-GHG emissions.
5 Panasonic exited the Flat Panel Display market in 2015. Panasonic reported emissions consistently while their facilities
were producing flat panel displays.

suppliers implement to reduce F-GHG emissions. For example, LG has replaced use of SF6 with NF3 in
the etch process, which has resulted in significant emissions reductions.
An optimal F-GHG emission intensity, based on full abatement and/or the fullest use of lower GWP
gases, could serve as an indicator on whether F-GHG emission reduction efforts have been implemented
to the fullest extent possible. In 2018, AU Optronics' F-GHG emission intensity was 0.0027 MtC02e/m2,
a 4% increase since 2017. Since 2005, their F-GHG intensity has been reduced over 95% from 0.0057
MtC02e/m2 in 2005 to 0.0027 MtC02e/m2. AUO's F-GHG emission intensity was the lowest publicly
reported intensity metric, however only three suppliers total (AUO, Innolux, and Hannstar) reported F-
GHG emission intensity for 2018.

•	The revised IEEE 1680.1 standard aims to foster greater sustainability in the Information Technology
(IT) supply chain since the criteria of the standard underpin the Electronic Product Environmental
Assessment Tool (EPEAT), a sustainability rating tool for certain electronics. An IT product receives an
EPEAT Bronze, Silver, or Gold rating. Bronze-rated products meet minimum required criteria only,
whereas Silver and Gold-rated products also meet additional amounts of optional criteria.
•	Computer and Display products that are "EPEAT registered" will be required to meet the IEEE 1680.1
standard. A registry of conformant products is publicly available at www.epeat.net as of November
2018.
•	Many institutional purchasers around the globe purchase EPEAT- registered products. By searching
the registry, purchasers can determine if EPEAT-registered products containing flat panel displays,
namely monitors and laptops, meet the optional F-GHG emissions reduction criterion.
By March 2020, 6048 EPEAT-registered products from six companies (ASUSTek, Acer, Google,
HP, Lenovo, Positivo Technologia S.A., and Teknoservice S.L.) had met the criteria for F-GHG
emissions reductions from flat panel display manufacturing
F-GHG Emissions in Context of Scope 1 and 2 Emissions Reductions
Efforts
As electronics brand owners increasingly request that suppliers report and reduce their Scope 1 and 2
emissions, several LCD suppliers have also begun to implement energy efficiency measures and
purchase renewable energy to mitigate their overall GHG emissions. Some suppliers provide detailed
insights on energy savings measures in their CDP and/or CSR reports. In some instances, where noted
in the profiles, it is unclear if efficiency measures apply to equipment that utilizes F-GHG more
efficiency, or if such measures apply to non-F-GHG equipment. EPA is interested in better
understanding the tradeoffs between reducing on-site combustion and electricity use and installing F-
GHG abatement measures that utilize on-site combustion or electricity use. Brand owners are
encouraged to engage suppliers on their holistic approaches to reducing both Scope 1 and 2
emissions. As such, where data is available, EPA has included information on other energy saving
measures under the "Emission Reduction Goals and Progress" sections.

The chart above shows the following separate but related metrics:
•	Market share over time shows the size of the supplier relative to all suppliers in the industry based on
area of panels produced.
•	Total emissions over time show total F-GHGs emitted by the supplier each year. Supplier emissions can
change due to the implementation of emissions reduction efforts, an increase or decrease in panel
production, and/or LCD technology advancements.
•	Emission intensity, noted where data is available¦, is a measure of the amount of F-GHG emissions per
unit of production. Trends in emission intensity show whether the supplier's rate of emissions is
increasing or decreasing over time and can indicate whether the supplier is implementing emission
reduction efforts. LG Display does not publicly report F-GHG emission intensity.
F-GHG emissions are publicly reported by suppliers through the CDP (formerly "Carbon Disclosure Project")
and/or corporate sustainability reports. In this graph, market share is calculated based on production data
from IHS Technology.
F-GHG Emission Reduction Activities
Overview
•	In 2018, LG Display emitted approximately 2,681,472MtC02e of F-GHG's as follows:
o PFCs: 191,622 MtC02e
o HFCs: 441 MtC02e
9
-------
o SF6: 2,489,245 MtC02e
Gases Targeted
•	SFs
•	PFCs
•	NF3
Processes Targeted
•	Etching
•	Cleaning
Approaches Used
Abatement
•	Abatement Systems: LG Display has installed F-GHG abatement systems on all lines of cleaning tools
and on two lines of etching tools. Electrically heated point-of-use systems are installed for NF3 in
cleaning tools and combustion-type centralized systems are installed for SF6 and PFCs in etch tools.
Process Improvements
•	LG Display has applied end-point detection and revised processes to optimize the use of F-GHGs.
Alternative Chemicals
•	SF6 Replacement: In 2014, LG Display developed a gas application technology as an alternative to
using SF6 and has started implementing the use of the alternative. In 2015, since joining the Korean
emission trading scheme, LG Display replaced SF6 as a process gas used in dry etching with NF3, which
has a lower GWP. At its Paju, Korea plant, the use of SF6 in 2017 decreased by 44% from 2015 levels.
The total amount of SF6 use in the overall plants in 2018 decreased by 38.2% compared to 2015, and
this is equivalent decrease to 1,279,626 tons of C02.
•	Remote Plasma Source Chamber Clean: LG Display has applied NF3 remote plasma source chamber
clean (RPSC) to all manufacturing lines. RPSC's utilization rate is 97% compared to 70% for an ordinary
chamber.
•	NF3 Replacement: LG Display has replaced NF3 with F2 in chamber cleaning on one of its
manufacturing lines. LG Display continues to research alternative lower GWP etching gases than SF6
for the dry etching process.
•	LGD invested 3.8 billion won (W) (in 2016, 1 W = 0.00088 USD7) for the development of clean
production technology to replace SF6 to respond to the greenhouse gas emissions trading scheme.
Currently, SF6 gas replacement technology is applied in major plant facilities to reduce greenhouse gas
emissions. In 2017, about 1.6 billion W was invested in scrubbers, which are process gas cracking
facilities to further reduce greenhouse gas emissions.

Emissions Measurement Approaches and Verification
•	LG Display uses national GHG emission estimation guidelines issued by the South Korean Ministry of
Environment and estimates NF3 emissions by using the 2006 Intergovernmental Panel on Climate
Change CIPCC) Guidelines for National Greenhouse Gas Inventories Tier 2b guidelines.
•	LG Display uses the CDM methodology AM0065 as the verification criteria for their SF6 replacement
processes since the methodology. This verification occurs once per year, and applies to domestic
facilities which have replaces SF6 with NF3.
•	LG Display's GHG emissions are verified by a third party in accordance with South Korean government
regulations. NF3 emissions estimated by the 2006 IPCC Tier 2b Guidelines for National Greenhouse Gas
Inventories for electronics industry emissions are not assured by a third party but cross-checked by
the World Display Device Industry Cooperation Committee (WDICC) members.
Emission Reduction Goals and Progress
•	LG Display set a target to reduce Scope 1 and Scope 2 GHG emissions 16.8% by 2022 and 65.1% by
2045, all relative to 2014 levels. Scope 1 emissions include F-GHGs.
•	LG Display reduced GHG emissions by 17.2% in 2018 compared to 2017 through process gas
replacement and energy saving campaigns.
•	At its Paju plant, LG Display reduced the use of SF6 in 2017 by 44% compared to 2016 through the
alternative use of NF3.
•	LG Display's F-GHG emissions reduction efforts are part of its broader goals to reduce corporate-wide
GHG emissions.
•	LG Display is subject to emissions caps under the Korean Emissions Trading Scheme (K-ETS) and has
been participating in GHG emissions trading since January 2015. The K-ETS is the first nationwide Cap-
and-Trade program in operation in East Asia.
•	In 2015, LG Display implemented its Carbon Footprint Calculator to respond to government GHG
regulations and respond to customer preference for environmentally friendly products.
LG Display is a member of the Korea Display Industry Association (KDIA), where it participates in an
environmental working group that promotes information exchange on GHG emissions reduction
technologies and initiatives. KDIA represents Korea's flat panel display suppliers in the World Display
device Industry Cooperation Committee (WDICC).

F-GHG Emission Reduction Activities
Overview
•	In 2018, Innolux emitted approximately 317,065 metric tons of C02 equivalent (MtC02e) of F-GHGs, as
follows:
o HFCs: 9,645MtC02e
o PFCs (includes NF3): 58,319 MtC02e (54,651MtC02e (NF3) + 3,668MtC02e (PFCs))
o SF6:249,102MtCO2e
•	In 2018, Innolux reported that removal (F-GHG abatement) equipment reduced total annual F-GHG
emissions by 2,821,486 MtC02e, compared to 3,029,691 MtC02e reduced in 2017, and 2,865,222
MtC02e reduced in 2016 (a 6.9% decrease compared to 2017).
•	In 2018, F-GHGs represented 8.8% of Innolux's overall GHG emissions compared to 10.6% of total
emissions in 2017s.
Emissions Intensity:
•	F-GHG intensity per substrate at the TFT-LCD stage of Taiwan has been reduced over 30% from 0.0094
MtC02e/m2 in 2010 to 0.0064 MtC02e/m2 in 2016.
•	In 2017, the F-GHG emission intensity per input substrate at the TFT-LCD stage of Taiwan sites was
0.0052 MtC02e/m2.
•	In 2018, the F-GHG emission intensity per input substrate at the TFT-LCD stage of Taiwan sites was
0.0044 MtC02e/m2, which was reduced 15.4% compared with 2017.
Gases Targeted
•	SFs	• HFCs
•	PFCs	• NF3
Processes Targeted
•	Cleaning
•	Etching
•	Innolux uses a small amount offluorinated heat transfer fluids but has not inventoried them. In
anticipation of the upcoming updates to the IPCC Guidelines, Innolux is documenting the amount of
heat transfer fluids purchased in 2015 to 2018.
Approaches Used
Abatement
•	Innolux has installed the tail gas treatment unit to conduct thermal destruction for reduction of F-
GHGs emission. Local combustion scrubbers were installed in Fab3 in Tainan to remove SF6 emitted
during the etching process by combustion.
8ln 2018, Innolux's total Scope 1 emissions accounted for 10.3% of their total emissions, meaning F-GHG emissions make
up the majority of Innolux's Scope 1 emissions.
14
-------
•	Innolux has installed local combustion scrubbers. In 2018, Innolux reported reducing
2,821,486MtC02e of F-GHGs9.
Process Improvements
•	Innolux is optimizing the use of F-GHGs in the process chambers. Additional details not available.
Alternative Chemicals
•	SF6 Replacement: Innolux has planned to replace SF6 with NF3 in the etching process in some of its
factories.
•	Innolux is using lower GWP gases, where possible.
Emissions Measurement Approaches and Verification
•	Innolux estimates F-GHG emissions based on the Tier 2b method for electronics industry emissions
provided in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.
•	Innolux received third party verification for its GHG inventory every year until 2017, which was verified
in accordance with the ISO 14064-3 standard.
•	In 2018, Innolux verified their emissions in accordance with the ISO 14064-3 standard.
•	Innolux has collected data for 13 years and passed the third-party verification according to ISO 14064-
1.
Emission Reduction Goals and Progress
•	In 2013, Innolux released its Product Carbon Footprint (PCF) system to help streamline calculations of
emissions on a per product basis.
•	In 2018, Innolux audited the carbon emissions of the top 89% of suppliers who inventoried their GHG
emissions. Innolux exceeded its 2018 target of reducing carbon emission of suppliers by
135,000MtCO2e and achieved a reduction of 136,513MtC02e.
•	Innolux plans to continue monitoring carbon emissions to establish a comprehensive database.
•	Innolux applied for early carbon credits for its carbon reduction efforts between 2005 and 2011,
receiving 16 million tons in credits in 2015 for Taiwan's cap and trade program.
•	In 2017, Innolux applied to the Taiwan EPA for the carbon offset program. The application for
reduction credits was agreed to after initial review, expecting a reduction of emissions by 35,000 C02e
per year. In 2018, Innolux acquired approval for this greenhouse gas exchange program. In 2018,
Innolux donated 2,048 energy-saving white LED tubes to replace the fluorescent tubes at Private
Changtai and Nursing Institute of Taiwan. It is estimated that the new lights will reduce carbon
emissions by 56,093 kg C02e.
9 F-GHG emission reductions reported by Innolux in February 2020. Innolux's CDP report includes 0.769 MMTCE, which
equals 2,819,667 Mt C02e, thus very similar F-GHGH emission reductions.
15
-------
• Innolux set a long-term goal for all manufacturing sites in Taiwan to reduce F-GHG emission intensity

Approaches Used
Information on Abatement, F-GHG Process Improvements, Alternative Chemicals, or other F-GHG
Reduction Approaches not publicly available.
Emissions Measurement Approaches and Verification
•	BOE's 2018 Scope 1 emissions sources include emissions statistics for natural gas, diesel, gasoline,
carbon dioxide fire extinguishers, personnel activities, refrigerants, and the use of SF6 and C02 in the
production process.
•	BOE's 2018 Scope 2 emissions are calculated from the C02 emissions generated by the consumption of
purchased electricity, using the China Development and Reform Commission's grid emission factor.
•	A third party provides reasonable assurance of BOE's Scope 1 and 2 emissions data according to the
I SO 14064-3 guidance.
Emission Reduction Goals and Progress
•	BOE set a goal to reduce Scope 1 and 2 emissions intensity by 20% from 2018 to 2028.
•	BOE set an energy usage goal to reduce the ratio of energy consumption (kwh) to dollars of output
value by ten thousand dollars of output value in 2028 compared to 2017 levels.
•	BOE's green development targets include aiming to become a leading exemplar of green development
in the industry by 2022 by demonstrating the lowest levels of energy/water consumption and
direct/indirect greenhouse gas emissions per unit of added value or per unit of product in the
industry.
•	In total BOE has completed implementation of 38 emissions reductions initiatives, with four additional
projects in early stages. The 38 completed initiatives reduce an estimated 152,162 MtC02e annually.
18
-------
•	Heat recovery and cooling technology: BOE is using air compressor waste heat recovery to reduce
power consumption and improve heat recovery, saving an estimated 9329 metric tons of C02
annually. BOE also introduced a condenser improvement project, air temperature optimization
project, pre-cooling equipment, free cooling project, and low temperature FGI project.
•	Process optimization: BOE introduced an air conditioning energy management system and changed its
cooling tower fan to an inverter fan to conserve energy. BOE also improved its air compressor group
control system, positively reduced its clean room pressure, adjusted FFU speed, reduced APP rated
voltage, and began transformer optimization management.
•	Equipment modification: BOE increased process efficiency by improving their vacuum inverter and
modifying their AN04 equipment, OVEN equipment, CIPI equipment, and PA equipment. Additionally,
BOE made improvements to their gluing machine, zero gas consumption desiccants, blower system,
module workshop washing machine dryer and pure water system fans.
•	Chemical Recycling: At BOE's CF factory, the organic diluent vapor in the exhaust is condensed and
recycled for use in machine cleaning. Additionally, BOE's scrapped VOCs are returned to the
manufacturing factory for recycling.
•	In 2018, BOE introduced 3 new projects to address other types of emissions, which resulted in a
reduction of 990 tons C02, 298.93 kg CL2, 2.96 tons nitrogen, 29.64 tons ammonia nitrogen, and 6.34
tons fluorine.

F-GHG Emission Reduction Activities
Overview
•	In 2018, AUO emitted approximately 170,282metric tons of C02 equivalent (MtC02e) of F-GHGs, as
follows:
o HFCs: 3,801 MtC02e
o PFCs (includes NF3): 27,232 MtC02e (24,893 MtC02e (NF3) + 2,339 MtC02e (PFCs))
o SF6: 139,249MtC02e
•	From 2003 to 2018, AUO reduced total F-GHG emissions by 16.4 million metric tons C02e.
•	Together, F-GHGs used during the production process and fuel emissions of utility systems comprise
most of AUO's Scope 1 emissions, representing 8.87% of AUO's total GHG emissions.
Emissions Intensity:
•	In 2018, AUO's F-GHG emission intensity was 0.0027 MtC02e/m2, a 4% increase since 2017. Since 2005
F-GHG intensity has been reduced over 95% from 0.057 MtC02e/m2 in 2005 to 0.0027 MtC02e/m2.
•	From 2010 to 2018, AUO reduced its overall GHG emissions intensity, which includes both Scope 1 and
Scope 2 GHG emissions, by 11%, from 58.5 kg C02e/m2 (0.059 MtC02e/m2) of panel produced to 51.9
kg C02e/m2 (0.052 MtC02e/m2). Since 2005, AUO has reduced the Scope 1 and Scope 2 GHG emissions
per unit area of production by 69%.
•	AUO has pledged to continue its efforts to achieve an additional 5% reduction in emissions intensity
by 2020 to attain their 25% GHG emission reduction goal.
Gases Targeted
•	SFs	• HFCs
•	PFCs (specifically CF4)	• NF3
Processes Targeted
•	Etching
•	Cleaning
•	Cooling: Per the "Guidance for Greenhouse Gas Accounting and Reporting for GHG inventory"
published by the Taiwanese EPA, emissions from fluorinated heat transfer fluids are too minor in AUO's
process to account for.
Approaches Used
Abatement
•	Localized Abatement Systems: As of 2015, AUO has installed localized, point-of-use abatement
systems in all fabrication facilities (fabs).
•	Abatement for Cleaning: AUO uses combustion abatement systems for cleaning processes in all fabs.
21
-------
•	Abatement for Etching: AUO uses combustion abatement systems or membrane separation
technology for dry etching processes on all new production lines (built after 2003).
Process Improvements
•	Reduced SF6 Consumption: AUO's process experts worked with its SF6 supplier to implement ways to
reduce the quantity of SF6 used in etching across all fabs. At one of its fabs, at full production capacity,
adjusting relevant SF6 process parameters can result in reducing the equivalent of 32,000 metric tons
of C02 annually, which is equal to 18% of AUO's reported SF6 emissions in 2015.
•	Reduced Gas Waste and Improved Utilization Efficiencies: By installing flow meters and mass flow
controllers at the front of tool chambers, on-site engineers have been able to reduce unnecessary gas
waste and improve gas utilization efficiencies.
•	Alternative Chemicals
•	NF3 Substitution: AUO uses NF3 instead of SF6 in cleaning, since NF3 has a lower global warming
potential (GWP) and it is used more efficiently.
Emissions Measurement Approaches and Verification
•	AUO estimates F-GHG emissions based on the Tier 2b method for electronics industry emissions
provided in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, including use of
default destruction or removal efficiency (DRE) values for abatement.
•	A third party verifies AUO's raw data according to the ISO 14064-1 guidance (verification document
included below).
•	AUO uses external Energy Service Companies (ESCOs) to apply the IPMVP along with third-party
verification for a 3-year period to improve the materiality of the internal energy-saving proposals.
Emission Reduction Goals and Progress
•	AUO set a goal to reduce Scope 1 and 2 GHG emission intensity in all fabs globally by 25% from 2010
to 2015. AUO was able to achieve 20% of this goal. F-GHGs are included as part of Scope 1 emissions.
•	AUO set a subsequent goal for all manufacturing sites in Taiwan to reduce Scope 1 and 2 GHG
emission intensity per square meter of glass produced by 5% by 2020 compared to 2015.
•	AUO's subsequent goal has been to reduce its GHG emissions by 24.7% by 2020, with a 2015 base
year, for most of its Scope 1, 2 and some Scope 3 emissions (using the location-based accounting
method for Scope 2). AUO's newest goal is a 16.5% GHG emission reduction by 2025, with a 2017 base
year, for its Scope 1 and 2 emissions (using the location-based accounting method for Scope 2).
•	AUO has a "Green Solutions" initiative that addresses emissions reductions through operations, supply
chain improvements, and product design.
•	AUO announced its "Carbon 2020" strategy in 2015, which aims to reduce carbon emissions by 1
million tons by 2020 and implement strategies in all areas from the optimization of product design,
material usage, manufacturing processes and logistic options to the provision of energy-efficient
solutions to customers. AUO supports the Science Based Targets (SBT) for a 2°C scenario and reports
that it "has taken action in this direction."
•	Following AUO EPS 2025 Goals, AOU set reduction goals based on a lifecycle assessment to reduce
carbon emissions by up to 6.5 million tonnes C02e cumulatively by 2025.
22
-------
•	As of 2018, AUO was 79.1% of the way to reaching their 2020 goal with 2% attributed to green
transport and logistics, 32% attributed to green manufacturing, and 66% attributed to product
innovation.
•	In 2018, AUO began incorporating downstream transportation and distribution into their GHG
inventory. They estimated total emissions to be 69,525 Mt C02e, which includes product weight per
trip, distance traveled, and mode of transport. These emissions will be tracked in further GHG
inventories.
•	In 2018, the Green Production Team under the Green Manufacturing Subcommittee implemented 698
projects and achieved 96,450 MWh electricity saved. In total, these projected helped avoid 53,433
metric tons of C02e emissions.
Participation in Broader F-GHG Reduction Efforts
•	AUO is a member of Taiwan's TFT-LCD Association (TTLA). The TTLA participates on behalf of Taiwan's
LCD suppliers in the World Display device Industry Cooperation (WDICC), whose members have
agreed to 30% F-GHG emission reductions by 2020 relative to 2010 levels.
•	AUO participates in the Product Attribute to Impact Algorithm (PAIA) Project to develop lifecycle
impact calculation tools for LCDs, capturing F-GHG emissions information. AUO has employed a
methodology to manufacture low-carbon LCD products, including 15.6" notebook panels, 65" and 55"
curve panels, and 18.5" to 24" desktop monitors.
•	AUO has engaged in developing the SF6 abatement verification methodology for LCD industries in
Taiwan.
•	AUO received 9.56 million tons of tradeable carbon credits by the Taiwan EPA for its early action on
PFC reductions and third-party verification of its F-GHG abatement. In both 2016 and 2017, AUO
signed the largest carbon credit trading deals in Taiwan. A total of 5 million tons were traded through
the Taiwan EPA's domestic carbon trading platform in both years.
•	AUO carbon credit assets were used to promote carbon neutrality and reduction. As of 2018, a total of
6 companies' building and activity carbon neutrality projects have been completed along with 15
carbon neutrality applications from external non-profit organizations.

•	Market share over time shows the size of the supplier relative to all suppliers in the industry based on
area of panels produced.
•	Total emissions over time show total F-GHGs emitted by the supplier each year. Supplier emissions can
change due to the implementation of emissions reduction efforts, an increase or decrease in panel
production, and/or LCD technology advancements.
•	Emission intensity, noted where data is available¦, is a measure of the amount of F-GHG emissions per
unit of production. Trends in emission intensity show whether the supplier's rate of emissions is
increasing or decreasing over time and can indicate whether the supplier is implementing emission
reduction efforts. HannStar does not publicly report F-GHG emissions but does report total GHG
emission intensity, as noted in the section below.
F-GHG emissions are publicly reported by suppliers through the CDP (formerly "Carbon Disclosure Project")
and/or corporate sustainability reports. In this graph, market share is calculated based on production data
from IHS Technology.

F-GHG Emission Reduction Activities
Overview
•	HannStar did not report total F-GHG emissions in 2018.
•	In 2018, HannStar reduced F-GHG emissions about 39,039MtCO2e by abatement equipment.
•	In 2018, F-GHGs emissions made up 24.55% of total GHG emissions, an improvement from 2017
(26.42%).
Emissions Intensity:
•	HannStar's GHG emission intensity decreased from 0.077 MtC02e/m2 in 2017 to 0.073 MtC02e/m2 in
2018.
Gases Targeted
•	SFs
•	NF3
Processes Targeted
•	Etching
•	Cleaning
Approaches Used
Abatement
•	Hannstar has installed the thermal abatement to remove F-GHGs emission at thin film process and
new etching equipment.
Alternative Chemicals
•	HannStar is using lower GWP gases, where possible. Additional details not available.
Emissions Measurement Approaches and Verification
•	HannStar estimates F-GHG emissions based on the Tier 2b method for electronics industry emissions
provided in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.
•	HannStar's plants in Taiwan have been developing GHG inventories and implementing third party
verification with reference to ISO 14064-1 since 2005.
Emission Reduction Goals and Progress
•	Since HannStar's GHG emissions are mostly due to electricity consumption and the use of F-GHGs in
flat panel display manufacturing, the company has focused its GHG reduction efforts on these two
areas.
•	HannStar applied for GHG early action offset credits based on the Taiwan EPA's Principles for
Promoting Greenhouse Gas Pilot and Offset Projects and the Announced GHG Emission Intensity for
TFT-LCD Industry.
•	In 2015, Taiwan's EPA awarded Hannstar 3.78 million tons of carbon credits for their early action in
voluntary GHG reductions.

F-GHG Emission Reduction Activities
Overview
•	CPT's 2018 emissions data are not publicly available. 2018 represents the last full year of CPT
operations, as CPT closed in 2019.
•	In 2017, PFC emissions accounted for 30.27% of CPTs GHG emissions which were 769,615 MtC02e.
Based on this information, CPTs PFC emissions for 2017 were estimated to be 232,962 MtC02e, a 5%
decrease since 2016.
•	In 2016, CPT emitted approximately 247,112 metric tons of C02 equivalent (MtC02e) of F-GHGs, a 55%
reduction from 2008, compared to a 49% reduction from 2008 in 2015 (313,000 MtC02e).
•	Between 2002 and 2017, CPT reduced F-GHG emissions by approximately 36.15 million MtC02e. This is
equivalent to removing 7.7 million vehicles from the road for one year.
Gases Targeted
•	SFs	• HFCs
•	PFCs	• NF3
Processes Targeted
•	Etching
•	Cleaning
Approaches Used
Abatement
•	Abatement Systems: CPT has installed abatement systems in all newer generation fabrication facilities
(fabs).
Process Improvements
•	PFC Reduction: In 2014, CPT implemented PFC reduction methods and evaluated process equipment,
targeting its 4.5 generation fabs, an earlier generation of fabs built prior to 2004. CPT conforms to the
WDICC resolution set in 2003 requiring that new plants install F-GHGs treatment facilities.
•	Cleaning Process: CPT completed reconstruction of the cleaning process in their Taoyuan and Longtan
plants, resulting in a 38% emission reduction of fluorinated compounds in 2011 from 2010 levels,
equal to approximately 170,000 MtC02e.
Alternative Chemicals
•	SF6 Replacement: CPT is using lower GWP gases, where possible. For example, CPT continues to
implement carbon reduction activities by replacing SF6 with NF3 in cleaning processes.
Emissions Measurement Approaches and Verification
•	CPT estimates its F-GHG emissions based on the Tier 2b method provided by the 2006 IPCC Guidelines
for National Greenhouse Gas Inventories for electronics industry emissions.
•	CPT's GHG inventory undergoes third-party verification and relies on the ISO14064-1 greenhouse gas
management system.
36
-------
•	CPT details their GHG emission reporting requirements under the Regulations Governing GHG
Emission Reporting in their Corporate Social Responsibility Report.
Emission Reduction Goals and Progress
•	CPT set a goal to reduce GHG emissions by 280,000 MtC02e from 2013 to 2016 through process
optimization, adoption of dry etch machinery, and installation of tail gas incinerator facilities.
•	In 2017, emissions dropped to 769,615 tons C02, which represents a decrease by around 411,000 tons
C02 or 34.82% compared to 2008.
•	In 2016, CPT's GHG emissions were 778,618 MtC02e, an increase from 778, 618 MtC02e in 2016. The
majority of CPT's GHG emissions are from F-GHG process emissions and electricity use.
Participation in Broader F-GHG Reduction Efforts
•	CPT is a member of the Taiwan's TFT-LCD Association (TTLA). The TTLA participates on behalf of
Taiwan's LCD suppliers in the World Display device Industry Cooperation (WDICC), whose members
have agreed to 30% F-GHG emission reductions by 2020 relative to 2010 levels. CPT will work with
TTLA to provide regular emission information of fluorinated compounds and engage in reductions of
fluorinated compounds.
