TSMC Selected As DJSI Member For Eighth Straight Year and Joins Carbon Disclosure Leadership Index For First Time

Hsinchu, Taiwan, R.O.C., Sept 26, 2008 –TSMC today announced that the company has been selected as a member of the Dow Jones Sustainability Indexes (DJSI) for an eighth consecutive year, and has also been chosen by the Carbon Disclosure Project (CDP) to join the Carbon Disclosure Leadership Index (CDLI) for the first time. TSMC is the only Taiwan company to enter the CDLI.

The Dow Jones Sustainability Indexes were launched in 1999 and TSMC joined in 2001. TSMC was the first Taiwan company to join the DJSI, and the only Taiwan company selected for membership for eight consecutive years. The DJSI evaluates companies along economic, environmental, and social dimensions, and this year TSMC achieved the highest scores in the semiconductor industry for “risk and crisis management”, “product quality and recall management”, “environmental policy/management system” and “climate strategy”. TSMC’s outstanding overall performance in all three dimensions has once again affirmed the company’s achievements and commitment to sustainable development.

The Dow Jones Sustainability Indexes (DJSI), are based on the cooperation of Dow Jones Indexes, STOXX Ltd. and SAM Group of Zurich, Switzerland. TSMC is a member of the Dow Jones Sustainability World Index, which selects the top 10% of 2,500 major global companies based on economic, environmental, and social criteria to provide a benchmark for socially responsible investors.

In addition, the Carbon Disclosure Project has included TSMC in its Carbon Disclosure Leadership Index for the first time this year with a score of 95. This marks the fourth year of TSMC’s participation in the CDP and demonstrates that TSMC’s pro-active stance in disclosing carbon emissions information and responding to climate change has received international recognition.

The CDP is an independent non-profit organization that invites constituent companies of the FTSE Global 500 Index to provide information on carbon emissions, and offers information on these companies’ climate change governance to investors.

“We are very happy that we have received recognition for our years of effort in environmental protection,” said TSMC Chief Executive Officer Dr. Rick Tsai. “TSMC will continue to fulfill its responsibilities as a good corporate citizen and contribute to the sustainability of the Earth.”
