NEW YORK- March 19, 2007- Alcoa (NYSE:AA) announced today that it has joined with a group of businesses and institutional investors in a call to action for the U.S. government to establish a national policy on climate change.

The group, organized by Ceres and its Investor Network of Climate Risk, represents dozens of institutional investors managing $4.4 trillion in assets and a number of leading U.S. companies, including Alcoa.

Ceres, whose goal is to advance corporate responsibility among its coalition members, worked with the businesses and institutional investors to formulate the call to action and announced its intentions today in Washington, D.C. Organizers point out that the Ceres-sponsored network complements recent climate change statements by the U.S. Climate Action Partnership (USCAP) and the Global Roundtable on Climate Change (GROCC). Alcoa is a founding member of USCAP and an active participant in the GROCC. These groups unite corporations, NGOs and other stakeholders in the fight against global warming.
