  • (*1)
    CO2 emissions:The CO2 conversion factor for purchased electricity in the Environmental Action Plan results report is calculated as 0.497 ton-CO2/MWh in FY 2018, 0.461 ton-CO2/MWh in FY 2019, 0.444 ton-CO2/MWh in FY 2020 and 0.441 ton-CO2/MWh in FY 20201.
  • (*2)
    Emissions other CO2:These are converted to equivalent amounts of CO2 using the global warning potential (GWP) of each gas.
