In order to calculate CO2 emission level calculation in relation to electricity, we have used the factor provided by the "List of Calculation Methods/ Emission Factors in the Calculation, Report and Publication System" of the Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan, adjusted conversion factors for individual power businesses based on the Act on Promotion of Global Warming Countermeasures. For figures that represent outside of Japan, the latest values for the each fiscal year supplied by power supply companies. When the CO2 emission levels are uncertain, we use the conversion factors of previous year. For the CO2 emission factor for gas and fuel at the time of calculation, we used the factor provided by the "List of Calculation Methods/ Emission Factors in the Calculation, Report and Publication System" of the Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan.

Third-Party Verification
Renesas Group receives third-party verification by Japan Quality Assurance Organization (JQA) in order to ensure the reliability of Environmental data.
2025 JQA Independent Verification Report
2024 JQA Independent Verification Report
2023 JQA Independent Verification Report
2022 JQA Independent Verification Report
The greenhouse gas (GHG) emissions for the fiscal year 2022 were calculated using the emission factors announced on January 24, 2023 for the fiscal year 2021. These calculations have been verified by a third-party verification from JQA. The impact – regarding the correction measures for miscalculations in the emission factors for year of 2021, resulting from the miscalculation of the emission factors for the fiscal year 2021 (METI) of this time, qualifies as a subsequent event. Nevertheless, since it falls below the quantitative materiality threshold (Confirmed by the verification agency), our company has not conducted any additional third-party verification.
