UMC First Taiwanese Company Listed on CDP's Climate Performance Leadership Index

Milestone follows shorty after UMC wins Taiwan's CSR Award for Excellence in Sustainability


Hsinchu, Taiwan, November 29, 2013 – United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) ("UMC" or "The Company"), a leading global semiconductor foundry, today announced that the company has been honored as the first Taiwanese corporation to be listed as a Climate Performance Leadership Index (CPLI) component by Carbon Disclosure Project (CDP). The foundry was also concurrently listed on CDP's Climate Disclosure Leadership Index (CDLI). UMC achieved the highest scores among all Taiwanese enterprises that participated this year, and is also the only Taiwanese company simultaneously listed for both indices since CDP published its first assessment report in 2003. The international recognition coincided with UMC receiving Taiwan Institute for Sustainable Energy's Corporate Social Responsibility (CSR) Award for continued excellence in transparent disclosure and sustainable performance.

Po Wen Yen, CEO at UMC, said, "We are pleased at UMC's selection as both CDLI and CPLI components by CDP. UMC strives for excellence in technology development and manufacturing, but at the same time is committed to the promise of a sustainable environment. Being recognized by international investors and sustainability organizations underscores UMC's industry leading position in sustainable operations and further motivates us to establish and achieve higher CSR goals.”

UMC has participated in CDP since 2006 with improvements every year. The foundry's score of 91A in 2013 was the highest among all Taiwan companies participating. With regard to Taiwan Institute for Sustainable Energy's CSR Award, UMC has achieved top place in Taiwan 6 years in a row since the award was first issued in 2008, and is one of the earliest and the most highly awarded participants.

About CDP
CDP is an international, not-for-profit organization providing the only global system for companies and cities to measure, disclose, manage and share vital environmental information.
CDP investor initiatives – backed in 2013 by more than 722 institutional investors representing an excess of US$87 trillion in assets – give investors access to a global source of year-on-year information that supports long-term objective analysis.

CDP requests standardized climate change, water and forest information from some of the world's largest listed companies through annual questionnaires sent on behalf of institutional investors that endorse them as ‘CDP signatories'. These shareholder requests for information encourage companies to account for and be transparent about environmental risk. Transparency of this data throughout the global market place ensures the financial community has access to the best available corporate climate change information to help drive investment flows towards a low carbon and more sustainable economy.

The disclosure score reflects the comprehensiveness of a company's response in terms of the depth and breadth of its answers.

A performance band is a measure of the positive actions that the company has demonstrated through their CDP response. These include actions to promote climate change mitigation, adaptation and transparency. It is represented by a letter from A to E, (including an A- band).
