UMC Honors 16 Suppliers for Outstanding Carbon Reduction Achievements

HSINCHU, Taiwan, December 3, 2025 - United Microelectronics Corporation (NYSE: UMC; TWSE: 2303)(“UMC”), a leading global semiconductor foundry, today hosted its “2025 UMC Low-Carbon Supplier Award Ceremony,” recognizing 16 supplier partners for their achievements in driving carbon emissions reduction. The top Carbon Reduction Pioneer Award was awarded to three companies—KLA, HOYA, and GlobalWafers—in recognition of their leadership and commitment to advancing decarbonization efforts across the supply chain.

 

SC Chien, Co-President and Chief Sustainability Officer of UMC, said: “In a rapidly evolving global environment, strengthening supply chain resilience and accelerating the net-zero transition are essential to overcoming the challenges ahead. In 2025, UMC officially received validation from the Science Based Targets initiative (SBTi) that our net-zero targets are aligned with the 1.5°C ambition. We will continue to work closely with all our partners to build a lower-carbon, more resilient supply chain.”

 

Since launching the Supply Chain Greenhouse Gas Inventory Initiative in 2022, UMC has supported suppliers through a strategic, step-by-step approach to greenhouse gas (GHG) inventory and emissions management. As of 2025, 422 suppliers have actively participated in the program, with the goal of engaging a total of 500 suppliers by 2027.

 

At this year’s ceremony, UMC honored suppliers that have demonstrated exemplary emissions reduction efforts and invited the companies to share practical experiences from their decarbonization journey. With the goal of cutting supply chain emissions by 20% by 2030, UMC will continue to support suppliers in accelerating emissions reduction from their operations while encouraging more partners to join the company’s initiative to build a more sustainable semiconductor ecosystem.
