Notes:The scope of aggregation has been changed to domestic non-consolidated until FY2017 and consolidated domestic and overseas from FY2018. Domestic and overseas consolidated refers to non-consolidated and consolidated subsidiaries. Domestic parentheses in parentheses include domestic non-consolidated and domestic consolidated subsidiaries.
Notes:Since the boundary was changed in FY2018, the “Result” column was changed to “N.A.”. Construction waste is managed by reducing the basic unit (amount generated from construction work / total floor area) and the final disposal rate (ratio of waste not reused), not the amount generated.

  1. The scope of aggregation has been changed to domestic non-consolidated until FY2017 and consolidated domestic and overseas from FY2018.
    Domestic and overseas consolidated refers to non-consolidated and consolidated subsidiaries. Domestic parentheses in parentheses include domestic non-consolidated and domestic consolidated subsidiaries.
  2. Until FY2017, total water is added to the water supply.
    Changed to only water supply usage excluding groundwater from FY2018.
    Since the boundary was changed in FY2018, the “Difference” column was changed to “N.A.”.
  3. Emissions into public wastewater are tabulated.
  4. Target has not been set because the boundary was changed from FY2018.
