Sumco

Sumco, a Japanese semiconductor and related device manufacturer, reported Scope 1 and 2 emissions of approximately 1.126 billion kg CO2e in 2025. This follows reported Scope 1 and 2 emissions of approximately 1.181 billion kg CO2e in 2024 and approximately 1.277 billion kg CO2e in 2023.

In 2020, Sumco reported total emissions of approximately 1.484 billion kg CO2e, comprising Scope 1 emissions of approximately 25 million kg CO2e, Scope 2 emissions of approximately 765 million kg CO2e, and Scope 3 emissions of approximately 694 million kg CO2e. In 2019, the company's total emissions were approximately 1.340 billion kg CO2e, with Scope 1 at approximately 26 million kg CO2e, Scope 2 at approximately 702 million kg CO2e, and Scope 3 at approximately 612 million kg CO2e. For 2018, total emissions were approximately 906 million kg CO2e, with Scope 1 at approximately 25 million kg CO2e, Scope 2 at approximately 877 million kg CO2e, and Scope 3 at approximately 4 million kg CO2e.

Sumco has set near-term Science Based Targets initiative (SBTi) commitments to reduce absolute Scope 1 and 2 GHG emissions by 42% by 2030, using 2023 as a base year. Additionally, the company aims to reduce absolute Scope 3 GHG emissions from purchased goods and services, capital goods, and upstream transportation and distribution by 25% within the same timeframe. These targets are consistent with reductions required to keep warming to 1.5°C. The company also has an internal target to reduce Scope 1 and 2 CO2 emissions by 33% by 2030, compared to 2014 levels, and achieve carbon neutrality (100% reduction) by 2050.
