Reporting of Environmental Data
・Reporting period: Fiscal year from April 1 to March 31 of the following year
・Reporting period: 72 Epson Group companies in Japan and overseas
・Unit: t is used for metric tons
・Totals may not match the sum of their components due to rounding off of fractions

Energy consumption

* Self-generated electricity from fuel sources such as cogeneration systems (CGS) is not included.
* Some figures differ from those reported in the past because they exclude self-generated electricity from fuel sources such as cogeneration systems (CGS) due to a review of the aggregation items.

Greenhouse gas emissions (scopes 1, 2, and 3)

Scope 1: Direct GHG emissions (LPG, LNG, natural gas, kerosene, heavy fuel oil, gasoline, PFCs, etc.)
Scope 2: Indirect GHG emissions (electricity and steam, etc.)
Scope 3: Scope 3: Indirect GHG emissions of the entire value chain
* Calculations are based on the GHG Protocol. In addition, calculations are based on the latest SBT standard since FY2017 and FY2023.

Scope 1 emissions by type (FY2025)

* For fiscal year 2017 and from fiscal year 2023 onwards, calculations are based on the latest SBT standards.
* Calculation of scope 1 and 2 emissions is based on the control approach and financial control approaches, and covers affiliated companies in which Seiko Epson Corporation has a stake of 50% or more.
*CO₂conversion factor of greenhouse gas emissions
Electric power: Disclose market-based emissions. In Japan, we use the adjusted emissions factors for the load serving entities (i.e., utilities) from which our sites purchase electricity, pursuant to Load Serving Entity Emission Factors announced by the Ministry of Environment and the Ministry of Economy, Trade and Industry. Overseas, we use the emission factors of the electricity retailers contracted at each site or the emission factors of the IEA (International Energy Agency) for each country. The emission factor is set to zero for the amount of renewable energy certificates and J-Credits utilized.
Fuel: The factors announced by the IPCC in 2019 were used for both domestic and overseas data.
GHGs other than CO₂: Equivalents were calculated based on 100-year GWP values in the Fifth Assessment Report (AR5) of the IPCC. AR6 is used from 2024 onwards.

Greenhouse gas emission (scope 3)

* Calculations for FY2017 and FY2023 onward are based on the latest SBT criteria.
* CO ₂conversion factor of greenhouse gas emissions
Category 1: Factors of the National Institute of Advanced Industrial Science and Technology (AIST) are used after FY2022. IDEA LCIA IPCC 2021 GWP 100a (latest Ver. 3.4)
Category 4: Used WTW (well-to-wheel) of the latest emissions intensity of GHG Protocol, GLEC, and IDEA.
Category 11: Used the global average of the latest IEA Emissions Factors.
Other: Used the latest version of the emissions intensity database available at Ministry of the Environment.

Calculation method

Category 1	Multiplied the mass of materials that comprise sold products by their emission factors. For items other than raw materials and components, the calculation is done by multiplying the cost under each accounting item by the corresponding emission factor.
Category 2	Multiplied the capital expenditure in each investment account by emission factors
Category 3	Multiplied the amount of each type of energy used at each site by their emission factors
Category 4	Emissions from transportation to Epson of products and services purchased from suppliers, and emissions from the transport of goods by Epson, were calculated by multiplying the mass of transported goods and the distance transported by emissions factors. Emissions associated with distribution centers are calculated by multiplying the mass of cargo handled by the emissions intensity.
Category 5	Multiplied the amount of each type of waste generated at each site by their emission factors
Category 6	Multiplied the transportation expenses for each transportation mode expenses by their emission factors
Category 7	Multiplied the transportation expenses for each transportation mode expenses by their emission factors
Category 8	For emissions from the operation of leased assets (excluding those not already included in scope 1 or scope 2 inventories), the floor area of leased buildings was multiplied by emission factors (if the amount of electricity purchased from the tenant-owner cannot be determined directly)
Category 9	Multiplied the sold product not shipped by Epson and the average distances of transported volumes by their emission factors per unit
Category 10	Excluded (because it is virtually impossible to reasonably estimate a calculation of processing by customers for device products and because the emissions are neglibible in relation to the total emissions)
Category 11	Multiplied the estimated electricity consumption over the lifetime of sold products by an emission factor
Category 12	Multiplied the mass of each type of waste treated by the emission factor for each type of waste treatment
Category 13	Not applicable (We have no assets leased to customers)
Category 14	Not applicable (We have no franchise business)
Category 15	Affiliate emissions multiplied by the equity share.

Third-party verification of greenhouse gas (GHG) emissions
We have a third party verify our calculations to ensure reliability. Our FY2025 GHG emissions (scopes 1, 2 and 3) , energy use and retired reductions data were verified as having been measured and calculated accurately, and a independent verification report was obtained.

Industrial waste emissions

Water withdrawal by source

* Industrial water is included in municipal water.
* No water was withdrawn from other sources.

Recycling water

* Recycled ratio=recycled water / (water usage + recycled water)

Water discharge by destination

* Water consumption=Total water withdrawal-Total water discharge.
* No water was discharged into other destinations.

Third-party verification of water
We have a third party verify our FY2025 data.

¹ Pollutant Release and Transfer Register.
² Volatile Organic Compounds. We report VOC emissions based on the voluntary action plans of four electric and electronic organizations.
