TS Wu, Vice President of UMC, said, "UMC is pleased to sign this landmark power purchase agreement with CIP’s Fengmiao I, marking UMC’s largest renewable energy deal to date and a significant milestone in our net zero journey. This agreement demonstrates our commitment to sustainable development to our stakeholders, and also contributes to UMC’s carbon reduction goals and ESG vision. As a responsible corporate citizen, UMC actively works on cutting emissions and energy consumption by installing high efficiency greenhouse gas abatement equipment and improving the energy efficiency of our manufacturing processes. At the same time, we will continue to expand renewable energy use as we advance towards our 2050 net zero goal.”

Thomas Wibe Poulsen, APAC Regional Partner for CIP’s Flagship Funds and Chairman of Fengmiao Offshore Wind Farm, said, “The decision of UMC, a leading global semiconductor company, to cooperate with Fengmiao I underscores the market’s high confidence in CIP’s technical and financial capability to deliver offshore wind projects.”

UMC follows its net zero roadmap, defined by science-based targets, by taking three key actions: persistent and proactive carbon emission reduction, 100% renewable energy usage, and investment in net- zero technologies. In 2023, UMC Group achieved a 26% reduction in scope 1 and scope 2 greenhouse gas emissions from 2020 base levels, reaching its 2030 target ahead of schedule. Therefore, UMC has revised its original 2030 target of 25% reduction to a more ambitious 42% reduction goal to accelerate the pace of its net zero transition.
