Greenhouse Gases

Greenhouse Gases emissions (Scope1、2)

■Calculation method

Total CO2 emissions = Σ (fuel consumption × CO2 emission factor) + Σ (purchased electricity consumption × CO2 emission factor)

CO2 emission factors

[Emissions from FY2020 to FY2023]

Japan

Fuel: Emission factor set in accordance with the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC2006)

Purchased electricity: Adjusted emission factor set in accordance with the Emission Factor by Electric Power Company published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry (2019 and 2020: R1 fiscal year; 2021: R2 fiscal year; and 2022: R3 fiscal year)

overseas

Fuel: Emission factor set in accordance with the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC2006)

Purchased electricity: Emission factor set in accordance with IEA (CO2 Emissions from Fuel Combustion) (FY2020 and 2021: IEA2017, 2019 edition、FY 2022: IEA 2019, 2021 edition; and FY2023: IEA 2020, 2022 edition)
