Greenhouse Gases

The CO2 equivalent is based on the coefficient for external announcement in the 7th Aisin Consolidated Environmental Action Plan. [SEE AISIN GROUP REPORT 2022 P.5] The CO2 equivalent of SF6 uses the global warming potential stipulated in the Enforcement Order of the Act on Promotion of Global Warming Countermeasures.
