- * The scope of environmental data calculation covers MIRARTH HOLDINGS and consolidated subsidiaries.
- * Scope 1 includes emissions from fuel combustion (gas, kerosene, gasoline), and Scope 2 covers electricity and cold-water usage.
- * Scope 1 and 2 have expanded their calculation boundaries and added more items to be included in the calculation starting from fiscal year 2022.
- * The performance figures for Scope 2 from fiscal year 2023 onwards reflect the environmental value of FIT non-fossil fuel certificates, etc.
- * Some of the Scope 3 figures prior to FY2022 are estimates. To improve calculation accuracy, the calculation method was revised from FY2023, and categories 8 and 15 were added from FY2025 to expand the scope of aggregation.
- * Our group excludes greenhouse gases other than CO₂ (such as CFCs) because they are present in extremely small amounts, and only calculates and reports CO₂.
- * The Scope 3 figures for fiscal year 2025 are provisional and may change.

- * The scope and period of calculation for energy data are based on the same conditions as for CO₂ calculation.
- * The figures for FY2023 and FY2024 have been changed to ensure consistency with the calculation of greenhouse gas emissions (location-based).
Third-Party Assurance
Our group obtains third-party assurance to ensure the reliability of our environmental data.
