United Microelectronics

United Microelectronics (UMC), headquartered in Taiwan, reported total carbon emissions of approximately 3,701,032,000 kg CO2e in 2024. This includes Scope 1 emissions of 463,670,000 kg CO2e, Scope 2 emissions of 1,523,855,000 kg CO2e, and Scope 3 emissions of 1,713,507,000 kg CO2e. Key categories within Scope 3 emissions for 2024 include purchased goods and services at 656,013,000 kg CO2e, capital goods at 424,251,000 kg CO2e, and fuel and energy-related activities at 370,697,000 kg CO2e.

Looking at previous years, UMC's total emissions were approximately 4,038,930,000 kg CO2e in 2023, 4,688,090,000 kg CO2e in 2022, and 5,608,642,000 kg CO2e in 2021.

UMC has set ambitious climate commitments validated by the Science Based Targets initiative (SBTi). The company commits to reach net-zero greenhouse gas emissions across its value chain by 2050. As part of its near-term targets, UMC aims to reduce absolute Scope 1 and Scope 2 GHG emissions by 42% by 2030, using 2020 as a base year. Additionally, UMC targets a 25% reduction in absolute Scope 3 GHG emissions within the same timeframe. For its long-term targets, UMC commits to reducing absolute Scope 1 and Scope 2 GHG emissions by 95% by 2050 from a 2020 base year, and absolute Scope 3 GHG emissions by 90% within the same period.
