Coverage of ESG reporting

ESG data is compiled on a global consolidated basis, which includes Mitsui Kinzoku as well as domestic and overseas consolidated subsidiaries. Any differences are indicated in the notes.

About environmental data
・Totals do not add up in some cases due to rounding off of fractions.
・ Blank cells in some tables are due to no data collection at that time.
・ Part of the data for previous fiscal years have been revised due to a review of the calculation results.

*1 Figures for CO₂ emissions from energy consumption were calculated using emission factors derived in a manner conforming to the Act on Promotion of Global Warming Countermeasures. CO₂ emissions from purchased electricity in Japan were calculated using the latest adjusted emission factors of electric power suppliers (basic emission factors were used until FY2019). For overseas emission factors, we used the per-country emission factors, the CO₂ Emission Factors from Electricity for 2021 reported by IEA (Until FY2020, the Electricity Emission Factors reported by GHG PROTOCOL were used).
*2 We have received independent practitioner’s assurance for the energy-derived CO₂ emissions calculation.
Independent practitioner’s assurance report FY2018 FY2019 FY2020 FY2021 FY2022
*3 Figures for FY2022 by business sector were based on the new organization started in April 2022, and those until FY2021 were based on the old organization.
　　Others include the organizations under the Business Reconstruction Office of the Corporate Planning Department, and the Business Creation Sector.

*1 Non-consolidated basis in Japan. Data for FY2022 was obtained from the calculation made for the Category 4 boundary of Scope 3. Up to FY2021, the scope of data calculation covered the transportations designated as Specified Consigner by the Act on the Rational Use of Energy. Calculation using the previous method gives a result of 17,465 t-CO₂.
*2 Global consolidated basis. Data for FY2022 was obtained from the calculation made for the Category 5 boundary of Scope 3. Calculation was performed based on the Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (Ver 2.5) using the emission factors by waste type/disposal method (excluding the waste transportation process) in the Emission Factor Database on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (Ver 3.3). For the emission factors up to FY2021, the emission intensity database for calculating GHG emissions of organizations throughout the supply chain, Japan‘s Ministry of the Environment and Ministry of Economy, Trade and Industry (Ver. 2.6 and Ver. 3.0) was referenced.
