  • The two companies signed a Memorandum of Understanding to drive meaningful reductions in greenhouse gas emissions across their shared supply chain.
  • Infineon and UMC will support suppliers in developing and implementing decarbonization strategies, including setting their own science-based targets.
  • The partners will jointly engage suppliers with workshops and knowledge sharing.

Munich, Germany & Hsinchu, Taiwan – 4 March 2026 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) and United Microelectronics Corporation (UMC), (NYSE: UMC; TWSE: 2303), two leading semiconductor players, have signed a Memorandum of Understanding (MoU) to achieve synergy in driving the reduction of emissions across the supply chain and to further promote sustainability practices. 

The two long-term partners are committed to sustainability and have set credible, measurable and transparent emissions reduction targets. These were validated by the Science Based Targets Initiative (SBTi) in 2025 and are in line with the most ambitious goal of limiting global warming to 1.5°C above pre-industrial levels. As part of the MoU, the partners now aim to encourage suppliers to also set carbon reduction targets in line with the SBTi criteria. Infineon and UMC will actively engage with shared suppliers to help them formulate and implement decarbonization strategies. This will include for instance workshops for knowledge sharing and best practice development.

"Last year, the Science Based Targets initiative approved Infineon's ambitious CO2 emission reduction targets. The collaboration with our partners in line with SBTi is a fundamental part of our strategy to drive decarbonization in our ecosystem." said Elke Reichart, member of the Management Board and Chief Digital and Sustainability Officer of Infineon. “The partnership with UMC is another important step on this path.”

"Tackling CO2 emissions across the value chain is a complex challenge that requires deep collaboration with our wide network of upstream and downstream partners," said TS Wu, Senior Vice President in charge of global manufacturing and supply chain at UMC. "Infineon shares the same strong commitment as UMC to climate responsibility, and we are proud to form this partnership to help accelerate progress in building a greener and more sustainable semiconductor ecosystem." 

Specifically, Infineon has made a commitment to SBTi to reduce absolute scope 1 and 2 greenhouse gas emissions by 72.5 percent by 2030 compared to the base year 2019, which is in line with the SBTi-requirements for limiting global warming to 1.5°C. Scope 1 and 2 targets refer to the company's direct operations. Moreover, Infineon has included a scope 3 emission target commitment to address the majority of its emissions, which occur in the supply chain: 72.5 percent of its suppliers measured by emissions related to purchased goods and services, capital goods and upstream transportation and distribution are to have a science-based target by 2029. 

UMC was the first semiconductor foundry worldwide to obtain SBTi validation in 2022, and revised its targets to align with SBTi's most ambitious requirements in 2025. UMC targets reduction in scope 1 and 2 emissions by 42 percent and scope 3 emissions by 25 percent by 2030, compared to the base year 2020, with a goal of net-zero greenhouse gas emissions by 2050. 

Given that Scope 3 emissions generally account for the majority of companies' total emissions, the partners are convinced that collaboration is vital to achieving significant reductions. This is even more essential given the complexities of the semiconductor industry's multi-tiered supply chain. 

Collaboration with suppliers has been already an integral part of both companies' sustainability strategies. To drive progress, UMC has engaged with over 400 suppliers through its Supply Chain Greenhouse Gas Inventory Initiative since 2022, empowering them with tools and resources to measure and manage emissions. Infineon has similarly launched a supplier engagement program, working with over 100 suppliers since 2023 to set and implement science-based targets. The companies will now leverage their combined expertise and influence to promote sustainable action among their common suppliers.
