Onsemi

Onsemi, a US-headquartered Semiconductor and Related Device Manufacturing company, reported its latest carbon emissions for 2025. In 2025, Onsemi's Scope 1 emissions were 546,600,000 kg CO2e, Scope 2 emissions were 659,900,000 kg CO2e, and Scope 3 emissions were 736,600,000 kg CO2e. This resulted in a total calculated emissions sum for 2025 of 1,943,100,000 kg CO2e (about 1.94 million tonnes CO2e).

Looking at previous years, Onsemi's total calculated emissions were approximately 2.21 billion kg CO2e in 2024. In 2023, the company reported Scope 1 emissions of 828,600,000 kg CO2e and Scope 2 emissions of 714,000,000 kg CO2e. Scope 3 emissions for 2023 were partially disclosed at 237,700,000 kg CO2e for fuel- and energy-related activities. For 2022, Onsemi's Scope 1 emissions were 1,014,800,000 kg CO2e, Scope 2 emissions were 713,500,000 kg CO2e, and Scope 3 emissions totalled 1,748,300,000 kg CO2e, including significant contributions from purchased goods and services (1,267,100,000 kg CO2e) and fuel- and energy-related activities (222,300,000 kg CO2e). The total calculated emissions for 2022 were 3,476,600,000 kg CO2e (about 3.48 million tonnes CO2e).

Onsemi has set ambitious climate commitments and Science-Based Targets (SBTi) to reduce its carbon footprint. The company aims to achieve net-zero emissions across Scope 1, 2, and 3 by 2040 (Net Zero 2040).

Their near-term SBTi targets, validated for a 1.5°C trajectory, include:

• Reducing absolute Scope 1 and 2 GHG emissions by 58.8% by 2034 from a 2022 base year.
• Reducing absolute Scope 3 GHG emissions from fuel- and energy-related activities by 35.0% within the same timeframe (2022-2034).
• Ensuring that 71.3% of suppliers by emissions, covering purchased goods and services, capital goods, and upstream transportation and distribution, will have science-based targets by 2029.

Additional targets include:

• Reducing absolute Scope 1 GHG emissions by 46% by 2030 from a 2019 base year.
• Reducing absolute Scope 2 GHG emissions by 46% by 2030 from a 2019 base year.
• Reducing Scope 3 GHG emissions by 55% per dollar value added by 2030 from a 2019 base year.
• Reducing absolute Scope 1 and 2 GHG emissions by 42.0% by 2030 from a 2023 base year.
• Reducing Scope 3 GHG emissions from purchased goods and services, upstream transportation and distribution, and downstream transportation and distribution by 51.6% per unit produced by 2030 from a 2023 base year.

Onsemi also committed to using 50% renewable energy by 2030 and 100% renewable energy by 2040. Historically, in 2016 compared to 2015, Onsemi achieved a 6% reduction in normalized carbon emissions at its assembly and test operation facilities.
