  2. Only leases within the group; calculated for Scopes 1 and 2
  3. Not calculated due to difficulty in collecting necessary data for calculation
  4. Until FY2021, biomass feedstock was deducted from the total, but from FY2022, the calculation was changed to be done without deduction, and the figures until FY2021 were also revised accordingly. Scope 3 total values were revised accordingly.
  5. Out of scope as there were no relevant activities
  • Scope 3 for FY2022 has been revised due to a flaw in the calculation formula when the emission factor was changed.
