HSINCHU, Taiwan, April 22, 2013 /PRNewswire/ -- United Microelectronics
Corporation (NYSE: UMC; TWSE: 2303) ("UMC"), a leading global semiconductor
foundry, today announced the three-year plan to improve resource and energy
productivity and to reduce greenhouse emission. The announcement is timed with
Earth Day to promote environmental protection living concepts and fulfill the
company's commitment to corporate social responsibility. UMC's plan consists
of 4 reduction aspects: electricity use, water, waste, and carbon. The goals
are to achieve reductions of 3% electricity consumption, 6% water consumption
and 9% waste generation by 2015, while also surpassing World Semiconductor
Council's PFC reduction target by 2020.

Po-Wen Yen, CEO at UMC said, "After successfully achieving our 2010-2013
carbon reduction goals, we are happy to announce on Earth Day UMC's new
three-year plan to further improve resource and energy productivity. We
believe that through proactive action, we can continually fulfill green
accountability and manufacturing concepts. UMC can also further strengthen its
cost structure and green competitiveness by improving resource and energy
productivity towards our long-term environmental sustainability goal. By
championing resource sustainability and greenhouse gas reduction, we can live
up to the vision of creating a sustainable environment."

UMC is engaged in its 14^th year of company-wide environmental protection
activities. Through this new 3-year plan, the company is expected to reduce
electricity consumption by approximately 60 million kWh, equivalent to the
electricity used by 15,000 households each per year. 750,000 units of water
will also be reduced, about the yearly water consumption rate for 23,000
households. The carbon emission reduction from three years of electricity and
water conservation will reach 32.5 million kgCO2e, with waste generation
reduced by 2,000 tons.
