HSINCHU, Nov. 29, 2013 /PRNewswire/ -- 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).
