Infineon Technologies AG and United Microelectronics Corporation have signed a memorandum of understanding to strengthen collaboration on reducing emissions across their supply chains and advancing sustainability practices within the semiconductor industry.
Both companies have established measurable emissions reduction targets that were validated by the Science Based Targets Initiative in 2025 and align with the goal of limiting global warming to 1.5°C above pre-industrial levels. Through the agreement, Infineon and UMC plan to encourage their suppliers to adopt carbon reduction targets consistent with the SBTi framework.
The partnership will involve active engagement with shared suppliers to help them develop and implement decarbonization strategies. Planned activities include workshops focused on knowledge sharing, tools for emissions measurement, and the development of best practices for sustainability.
Infineon has committed to reducing its absolute scope 1 and scope 2 greenhouse gas emissions by 72.5% by 2030 compared with a 2019 baseline. These scopes cover emissions generated directly by the company’s operations. In addition, Infineon has set a scope 3 target addressing emissions across its supply chain, aiming for 72.5% of its suppliers, measured by emissions from purchased goods and services, capital goods, and upstream transportation and distribution, to establish science-based targets by 2029.
UMC was the first semiconductor foundry to obtain SBTi validation in 2022 and strengthened its commitments in 2025 to align with the initiative’s most ambitious standards. The company aims to reduce scope 1 and scope 2 emissions by 42% and scope 3 emissions by 25 percent by 2030 compared with a 2020 baseline, with a long-term goal of achieving net-zero greenhouse gas emissions by 2050.
Both companies emphasized that collaboration is critical because scope 3 emissions typically represent the largest share of total emissions within the semiconductor industry’s complex multi-tier supply chain. UMC has already engaged more than 400 suppliers through its Supply Chain Greenhouse Gas Inventory Initiative since 2022, while Infineon has worked with more than 100 suppliers since 2023 through its supplier engagement program to support the adoption of science-based targets.
Through the new partnership, Infineon and UMC plan to combine their experience and industry influence to accelerate sustainable practices and emissions reductions among their shared suppliers.
