Use of non-renewable energy

* Totals do not add up in some cases due to rounding off of fractions.

Use of renewable electricity

* Totals do not add up in some cases due to rounding off of fractions.
* Includes cogeneration systems (CGS) electricity and self-generated electricity. Since it is difficult to procure renewable energy fuels or green gas certificates that meets the RE100 technical criteria, we have achieved 100% renewable electricity by voluntarily applying renewable energy certificates equivalent to the amount of electricity used.

Greenhouse gas emission(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: Indirect GHG emissions of the entire value chain
* Totals do not add up in some cases due to rounding off of fractions.
* Since it is difficult to procure renewable energy fuels and green gas certificates that meet RE100 technical criteria, we voluntarily applying renewable energy certificates equivalent to the amount of electricity used, offsetting the equivalent CO₂ emissions from Scope 1.

Greenhouse gas emission (scopes 1, 2)

* Totals do not add up in some cases due to rounding off of fractions
* Since it is difficult to procure renewable energy fuels and green gas certificates that meet RE100 technical criteria, we voluntarily applying renewable energy certificates equivalent to the amount of electricity used, offsetting the equivalent CO₂emissions from Scope 1.
* Scopes 1 and 2 emissions are verified by a third party. Scope 2 location-based emissions are available only for FY2023.
* 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 of the IPCC.

Greenhouse gas emission (scope 3)

* Category 1: The National Institute of Advanced Industrial Science and Technology IDEA Ver.3.3 is used for calculations from FY2022.
¹ Data verified by a third party

Calculation method

Category 1	Multiplied the mass of materials that comprise sold products by their emission factors
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
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 and lodging expenses by their emission factors
Category 7	Multiplied the transportation expenses for each transportation mode 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
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	Multiplied the electricity consumed in the processing of intermediate products into finished products by emission factors
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	Not applicable (We do not engage in investment management)

Third-party verification of greenhouse gas (GHG) emissions
We have a third party verify our calculations to ensure reliability. Our FY2023 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

* Totals do not add up in some cases due to rounding off of fractions.

Water withdrawal by source

* Industrial water is included in municipal water.
* No water was withdrawn from other sources.
* Totals do not add up in some cases due to rounding off of fractions

Recycling water

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

Water discharge by destination

* Totals do not add up in some cases due to rounding off of fractions.
* 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 FY2023 data.

* Some figures differ from those in Sustainability Report 2023 due to a recalculation.
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.

* Company number includes Seiko Epson Corporation.

Collection

¹ Collected either voluntarily or as mandated by local law. Sum of amount actually collected and amount expected to be collected.

Groundwater trichloroethylene concentration trend (annual average in wells with highest concentration at each site)

Reference: Trichloroethylene standards
- Environmental quality standard for groundwater under Japan's Basic Environmental Law: 0.01 mg/L max.
- Groundwater remediation standard under Japan's Water Quality Pollution Control Act: 0.01 mg/L max.
- Groundwater standard under Japan's Soil Contamination Countermeasures Law: 0.01 mg/L max.
