Non-financial data
To improve the reliability of CO2 emission (Scope 1, Scope 2) data, the FY2025 figures marked with a ★ have been third-party assured by Asuene Veritas Inc. in accordance with the International Standard on Assurance Engagements (ISAE) 3000 and 3410.
[Calculation Method]
Scope 1: Calculated by multiplying the fuel usage of our consolidated group by the emission factor of the Ministry of the Environment's Accounting, Reporting, and Disclosure System (SHK System).
Scope 2 (Market-based): Calculated by multiplying the amount of electricity purchased at each location of our consolidated group by the emission factor corresponding to the contract type of each purchased electricity.
Scope 2 (Location-based): Calculated by multiplying the amount of electricity purchased at each location of our consolidated group by the average emission factor of the country/region in question.
