Note

  • *1. Through FY2024, the scope of calculation was progressively expanded, covering more than 95% of the Group’s total greenhouse gas emissions in accordance with SBT criteria.
    The organizational boundary is defined based on the operational control criterion of the GHG Protocol.
  • *2. Figures have been calculated using market-based coefficients since fiscal year 2022.
  • *3. In connection with the acquisition of SBT certification, data for fiscal year 2024 has been recalculated.
  • *4. Total energy consumption is calculated as the sum of purchased electricity and primary energy-converted amounts and therefore differs from the total of the figures shown in the table.
  • *5. Numerical errors have been corrected.
  • *6. Recycled volume refers to the amount other than landfill disposal.
  • *7. Hazardous waste volume refers to specially controlled industrial waste as defined under Japanese regulations.
  • *8. Final disposal volume refers to landfill disposal (zero emissions have been achieved in Japan).
  • *9. The figures have fluctuated as the number of sites and certified sites has increased.
