Fiscal 2019 Goals and Results and Fiscal 2020 Environmental Activity Plan

We achieved our goals in mitigating global warming, protecting biodiversity, and pursuing environmental friendly design in fiscal 2020. However, we did not achieve our goals in reducing the total volume of reducted and recycled construction by-products.

Notes: The boundary up to FY2017 was domestic only, and it was changed to consolidated domestic and overseas from FY2018.
Notes: Since the boundary was changed in FY2018, the “Result” column was changed to “N.A.”. In addition, regarding “own office + warehouse / factory”, only the company office was counted up to the target value for FY2018, and the actual value for FY2018 was added to the scope of calculation.

Notes: The boundary up to FT2017 was domestic only, and it was changed to 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.
