  • ＊2Scope 1: For domestic sites, the emission factors stipulated by the Act on Promotion of Global Warming Countermeasures are used. The emissions include those from renewable energy and waste incineration. For overseas sites, the emission factors stipulated by each country's laws and regulations are generally applied. Where specific factors are unavailable,  emission factors stiplulated by the Act on Promotion of Global Warming Countermeasures are used.
  • Scope 2: The emission factors are basically determined by the power contract or each country's laws and regulations. Where specific factors are not available, the latest factors published by “Emissions Factors 2023” of the International Energy Agency (IEA) are used instead. The emissions include those from renewable energy. When renewable energy or renewable energy certificates are used, an emission factor of zero is applied.
  • ＊3 “Emission Intensity Database for Calculating Greenhouse Gas Emissions of Organizations through Supply Chains” provided by Ministry of the Environment is used. In FY2023, CO2 emissions increased due to changes in calculation methods, such as revision of emission intensity allocation, and the growth in business operations.
