Calculation Method

Environmental Performance Indicator Unit Calculation Method
Greenhouse gases
Scope of domestic data collection: All domestic bases
Scope of overseas data collection: Research bases, production bases, offices (electricity only)
Greenhouse gas emissions Thousand t-CO2eq Data collected: CO2 equivalent emissions from energy (fuel and electricity) purchased at bases, fuel purchased for domestic company vehicles, and domestic leakage of fluorocarbons
Greenhouse gases: Σ (amount of each type of energy purchased x CO2 emissions factors for each type of energy) + Σ [(amount of fluorocarbons refilled - amount of fluorocarbons recovered when refilled) x GHG factor for each type of fluorocarbons]
Figures for fuel emissions factor are the totals calculated for each type of fuel based on the Greenhouse Gas Emission Calculation and Reporting Manual (Ver. 4.4) and of the Ministry of the Environment and the Ministry of Economy, Trade and Industry.
The emissions factor for electricity is calculated by the basic emissions factor of Emissions Factors for Electric Power Enterprises announced by The Ministry of the Environment and the Ministry of Economy, Trade and Industry on January 7, 2020 or the country-specific factor indicated in CO2 Emissions From Fuel Combustion (IEA 2017) by the International Energy Agency (IEA).
Scope 1 Thousand t-CO2eq Data collected: CO2-equivalent emissions from fuel purchased at bases, fuel for domestic company vehicles, and leaked fluorocarbons.
The method of calculation is the same as that for GHGs.
Scope 2 Thousand t-CO2eq Data collected: CO2-equivalent emissions from electricity purchased at bases.
The method of calculation is the same as that for GHGs.
Scope 3 Emissions in Category 1

Scope 3 Emissions in Category 3
Fuel- and energy-related activities not included in Scope 1 or 2
Thousand t-CO2eq Data collected: CO2-equivalent emissions from the collection, production, and transportation of energy purchased in Japan and overseas.
Greenhouse gases: Σ (amount of each type of energy purchased x CO2 emissions factors for each type of energy) The fuel emissions factor uses the LCI database (IDEAv2), and the electricity emissions factor uses the emissions unit values (Ministry of the Environment's database).

MTPC transportation is calculated using the ton-kilometer method in the Greenhouse Gas Emission Calculation and Reporting Manual (Ver. 4.4) from the Ministry of the Environment and Ministry of Economy, Trade and Industry.
Storage is calculated by taking the amount of electricity used in domestic distribution warehouses and promotional goods warehouses and multiplying it by the basic emission factor in Emissions Factors for Electric Power Enterprises announced by The Ministry of the Environment and the Ministry of Economy, Trade and Industry on January 7, 2020.
