United Microelectronics's reported carbon emissions

United Microelectronics Corporation (UMC), a prominent entity in the electrical machinery and apparatus sector headquartered in Taiwan, has reported its carbon emissions and set forth climate commitments. For the year 2024, UMC's total carbon emissions amounted to approximately 3.61 billion kg CO2e. This figure is comprised of Scope 1 emissions totalling about 463.7 million kg CO2e, Scope 2 emissions of approximately 1.52 billion kg CO2e, and Scope 3 emissions estimated at 1.71 billion kg CO2e. In 2023, UMC recorded total emissions of approximately 4.05 billion kg CO2e, with Scope 1 at 509.6 million kg CO2e, Scope 2 at 1.64 billion kg CO2e, and Scope 3 at 1.89 billion kg CO2e. The previous year, 2022, saw total emissions of around 4.69 billion kg CO2e, including 866.0 million kg CO2e for Scope 1, 1.76 billion kg CO2e for Scope 2, and 2.06 billion kg CO2e for Scope 3. UMC has established significant greenhouse gas reduction targets. The company aims for a 42% reduction in Scope 1 and Scope 2 emissions by 2030, using 2020 as the base year. Additionally, a 25% reduction in value chain (Scope 3) emissions is targeted within the same timeframe. Looking further ahead, UMC Group plans to achieve a net-zero target by 2050, with a commitment to reduce at least 90% of emissions and neutralise or offset the remaining unavoidable emissions. The Science Based Targets initiative (SBTi) has validated these near-term targets, aligning with a well-below 2°C scenario for Scope 1 and 2 emissions. UMC has also committed to long-term targets, including a 95% reduction in Scope 1 and 2 emissions by 2050 from a 2020 base year, and a 90% reduction in Scope 3 emissions by 2050.
