    ※ Calculation period: January 1st to December 31st.
    　 Data was collected from MJC on a non-consolidated basis (four domestic sites: Tokyo Headquarters, Aomori Plant, Aomori Matsuzaki Plant, and Oita TL) and from six overseas consolidated subsidiaries (TMC, MEK, MMK, CMC, MEC, and MEA).

    • ＊1　The emission factors used in the calculation were sourced from the "List of Calculation Methods and Emission Factors under the Act on Promotion of Global Warming Countermeasures" published by Japan's Ministry of the Environment and Ministry of Economy, Trade and Industry, as well as emission factors provided by electricity and gas suppliers.
      　　 The emission factors for 2024 are based on the 2023 emission factors.
      　　 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　Annual average 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 collected from four domestic sites (Tokyo Headquarters, Aomori Plant, Aomori Matsuzaki Plant, and Oita TL) and three overseas sites (TMC, MEK, MMK).
      The three remaining overseas sites (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.
