Mitsubishi Materials

Mitsubishi Materials, headquartered in Japan and operating in the cement, lime and plaster industry, reported Scope 1 and 2 emissions of approximately 688 million kg CO2e in 2025, alongside Scope 3 emissions of about 7.73 billion kg CO2e. In 2024, its Scope 1 and 2 emissions were approximately 887 million kg CO2e, which followed about 902 million kg CO2e in 2023, and roughly 949 million kg CO2e in 2022. For 2021, Scope 1 and 2 emissions stood at approximately 935 million kg CO2e. In 2020, the company disclosed Scope 1 emissions of about 9.3 billion kg CO2e and Scope 2 emissions of approximately 1.2 billion kg CO2e.

Mitsubishi Materials has set several climate commitments. It aims for a 47% reduction in Scope 1 and 2 GHG emissions by the fiscal year ending March 2031, compared to the fiscal year ended March 2021, excluding emissions from resource recycling efforts. Additionally, the company is working towards carbon neutrality, including resource recycling emissions, by the fiscal year ending March 2046. A key part of this strategy is to achieve a 100% renewable energy usage rate for electricity by the fiscal year ending March 2036.

The company has also committed to Science Based Targets initiative (SBTi) goals. Mitsubishi Materials Corporation aims to reduce absolute Scope 1 and 2 GHG emissions by 42% by FY2031 from a FY2021 base year. Furthermore, it commits to a 13% reduction in absolute Scope 3 GHG emissions from purchased goods and services, fuel and energy-related activities, and investments within the same timeframe. These Scope 1 and 2 targets are aligned with a 1.5°C global warming scenario.
