Onsemi's reported carbon emissions
Onsemi, headquartered in the US, reported a total of approximately 2.32 billion kg CO2e in emissions for 2024. This figure comprises Scope 1 emissions totalling about 776.5 million kg CO2e, Scope 2 emissions of approximately 690.8 million kg CO2e, and Scope 3 emissions amounting to around 948 million kg CO2e. For 2023, Onsemi's total emissions were approximately 3.11 billion kg CO2e, with Scope 1 at about 828.6 million kg CO2e, Scope 2 at approximately 714 million kg CO2e, and Scope 3 at around 1.56 billion kg CO2e. The company's climate commitments include a long-term goal to achieve Net Zero by 2040 across all scopes. This ambition was established with a baseline in 2023, aiming for emissions reduction by 2040. Onsemi also previously set a goal to use 50% renewable energy by 2030 and 100% by 2040. Furthermore, Onsemi has Science Based Targets initiative (SBTi) approved targets. These include a commitment to reduce absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 58.8% by 2034, using 2022 as the base year. For Scope 3 emissions, specifically from fuel- and energy-related activities, Onsemi commits to a 35% reduction within the same timeframe. Additionally, they aim for 71.3% of their suppliers, covering purchased goods and services, capital goods, and upstream transportation and distribution, to have science-based targets by 2029. Another set of SBTi targets from a 2019 base year aims for a 46% reduction in absolute Scope 1 and 2 GHG emissions by 2030. A separate intensity target from the same period commits to a 55% reduction in Scope 3 GHG emissions per dollar value added by 2030. More recently, Onsemi has set targets to reduce absolute Scope 1 and Scope 2 GHG emissions by 42.0% by 2030 from a 2023 base year. They also commit to 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.
