Mitsubishi Materials

Mitsubishi Materials, a Japanese company in the Cement, lime and plaster industry, reported Scope 1 and 2 emissions of about 688 million kg CO2e for 2025, alongside Scope 3 emissions of approximately 7.73 billion kg CO2e.

Looking back, their combined Scope 1 and 2 emissions have varied. In 2024, they were approximately 887 million kg CO2e, decreasing from about 902 million kg CO2e in 2023, 949 million kg CO2e in 2022, and 935 million kg CO2e in 2021. For 2020, Scope 1 emissions were around 9.3 billion kg CO2e and Scope 2 emissions were approximately 1.2 billion kg CO2e. Earlier data shows combined Scope 1 and 2 emissions of about 12.09 billion kg CO2e in 2016, 12.17 billion kg CO2e in 2017, and around 6.04 billion kg CO2e in 2012.

Mitsubishi Materials has set several climate commitments. They aim to reduce their Scope 1 and 2 GHG emissions by 47% by the fiscal year ending March 2031, compared to the fiscal year 2021 levels (excluding emissions from resource recycling efforts). They also have a target to reduce Scope 3 emissions for Categories 1, 3, and 15 by 22% or more by fiscal year 2031, from fiscal year 2021 levels. Furthermore, they are working towards achieving carbon neutrality, including GHG emissions from resource recycling efforts, by the fiscal year ending March 2046. A key part of this strategy is to reach a 100% renewable energy usage rate for electricity by the fiscal year ending March 2036.

The company's climate targets are validated by the Science Based Targets initiative (SBTi). Mitsubishi Materials Corporation commits to reducing absolute Scope 1 and 2 GHG emissions by 42% by fiscal year 2031 from a fiscal year 2021 base year. They also aim to reduce absolute Scope 3 GHG emissions from purchased goods and services, fuel and energy-related activities, and investments by 13% within the same timeframe. These targets for company operations (Scope 1 and 2) are consistent with the reductions required to keep global warming to 1.5°C.
