  • Note: Calculation period: January 1st to December 31st.
    Data was aggregated from four domestic sites and six overseas companies (TMC, MEK, MMK, CMC, MEC, and MEA).
  • *¹ The emission factors used in the calculations were based on the list provided by the Ministry of the Environment and the Ministry of Economy, Trade, and Industry under the “Calculation, Reporting, and Disclosure System,” as well as by electricity and gas supply companies.
    CO₂ emission factors for 2024 and 2025 are calculated using the emission factors from the respective preceding fiscal year.
    When specific emission factors were not available, conversion factors published by the International Energy Agency (IEA) were used.
    Scope 1: Direct emissions from fuel combustion and industrial processes at our facilities.
    Scope 2: Indirect emissions from the use of electricity, heat, or steam supplied by other companies.
  • *² Average yearly change rate in energy consumption per unit (%): This figure represents the average annual change in energy consumption per unit, with the previous fiscal year's unit value set at 100%.
  • *³ Data was aggregated from four domestic sites and three overseas companies (TMC, MEK, and MMK).
    The three overseas companies (CMC, MEC, and MEA) are excluded from the calculation as they operate within shared office sites.
  • *⁴ Wastewater volume includes discharges to sewage systems and public water bodies at each site.
    For sites where wastewater volumes could not be determined, the total volume of water intake was used as a proxy for wastewater discharge.
  • *⁵ Regarding the Aomori Plant water usage, “other” refers to non-potable sources such as river water, groundwater, and rainwater, while “other” volume of effluents indicates discharges into public water bodies.
