Infineon and UMC Partner to Cut Carbon Emissions in Semiconductor Supply Chains

Infineon Technologies AG and United Microelectronics Corp. (UMC) have formalized a strategic partnership aimed at reducing carbon emissions throughout their semiconductor supply chains while advancing sustainability practices across the industry. The two semiconductor giants announced they have signed a memorandum of understanding (MoU) that establishes a framework for collaborative efforts to drive decarbonization. The partnership places particular emphasis on working with suppliers to establish emissions reduction targets that align with the rigorous criteria set by the Science Based Targets initiative (SBTi). Both Infineon and UMC achieved a significant milestone in 2025 when they received validation from SBTi for their respective climate targets. These validated targets are consistent with global efforts to limit temperature increases to 1.5°C above pre-industrial levels, representing the most ambitious threshold outlined in international climate agreements. The collaboration between Infineon and UMC is structured around direct engagement with shared suppliers. The companies plan to help these suppliers develop comprehensive decarbonization strategies and implement practical solutions to reduce their carbon footprints. A key component of this initiative involves organizing workshops designed to facilitate knowledge sharing, promote best practices, and provide suppliers with the tools and guidance needed to set and achieve their own science-based emissions reduction targets. Elke Reichart, who serves as chief digital and sustainability officer at Infineon, emphasized that collaboration with industry
