United Microelectronics Corporation (UMC) Carbon Emissions and Climate Commitments

In 2024, United Microelectronics Corporation (UMC), headquartered in Taiwan and operating within the Electrical machinery and apparatus n.e.c. (31) industry, reported total carbon emissions of approximately 3.64 billion kg CO2e. This figure is comprised of Scope 1 emissions totalling about 463.67 million kg CO2e, Scope 2 emissions of approximately 1.52 billion kg CO2e, and Scope 3 emissions amounting to around 1.71 billion kg CO2e.

UMC has established ambitious climate targets. By 2030, the company aims to achieve a 42% reduction in Scope 1 and Scope 2 emissions, using 2020 as a baseline year. Furthermore, UMC is targeting a 25% reduction in its value chain emissions (Scope 3) within the same timeframe. Looking further ahead, UMC Group intends to reduce its emissions by at least 90% by 2050, with plans to neutralise or offset any remaining unavoidable emissions to reach net-zero.

The company's commitment to climate action is further underscored by its alignment with the Science Based Targets initiative (SBTi). UMC has set SBTi-aligned targets to reduce absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 25% by 2030, referencing a 2020 base year. Additionally, it has committed to a 12.3% reduction in absolute Scope 3 GHG emissions within the same period. Long-term goals include a 95% reduction in Scope 1 and 2 emissions by 2050, and a 90% reduction in Scope 3 emissions by 2050. UMC also has a commitment to reach net-zero GHG emissions across its value chain by 2050.
