* Totals may not match due to fractional rounding

  • Note 1:
    Emission factors
  • Electricity:
    In Japan, we use emissions factors as determined by the emissions output for each separate electric power utility, as specified in the Act on Promotion of Global Warming Countermeasures.
    Overseas, the International Energy Agency (IEA) emission factors for each country are the standard reference.
  • Fuel:
    Both in Japan and overseas, emissions are measured as the calorific value by type of fuel and emission factors for fuel use as specified in the Act on Promotion of Global Warming Countermeasures.
    However, if information such as calorific value is provided by the fuel supplier itself, that data is used.
  • Chilled/heated water:
    Emission factors provided by suppliers are used.
  • Note 2:
    Starting in FY2020, tenants, stores, warehouses, company vehicles, etc. have been added to the scope of calculation, but energy use by outsourced companies is not included.
  • Note 3:
    For stores, warehouses, etc., where the amount of electricity used cannot be specified, the amount of electricity is estimated from the floor area.
