*1 Calculated pursuant to the provisions of the Act on Rationalizing Energy Use and Shifting to Non-fossil Energy (revised Act on Rationalizing Energy Use, Act No. 49 of 1979). Scope 2 values are based on market standards. Due to the rollout of CO2-free electricity generation beginning in FY 2023/3, the values after deduction of the non-fossil certificate allocation amount are shown in parentheses.

Due to improved accuracy of the calculation method, values for previous years are for reference only.
