PITTSBURGH, PA - Alcoa (NYSE:AA) marked Earth Day 2003 with the release of its 2002 Sustainability Report, a detailed, data-based review of the company's global, environmental, social and economic performance. The report is available online at www.alcoa.com/lnk/sustainability .

In releasing the report, Alcoa Chairman and CEO, Alain Belda said that it represented another milestone in Alcoa's long tradition of measuring performance against the high standards set by the company and reporting publicly on progress made.

"Truth can be judged by performance, so data and factual information pervade this report," said Belda. "We have presented information that yields meaningful insight into our global operations, where we are making progress and where we are not yet performing to the standards we set for ourselves," he said.

Belda attributed the achievements outlined in the report to the hard work of 127,000 Alcoa employees in 40 countries. "Alcoa's employees are working effectively to drive waste from the value chain, from the natural resources that make our products all the way through the supply chain to the customer. That is how we secure the benefits and reduce the cost for our business, our customers, our communities, and our world. This is how we demonstrate leadership.' he said.

Highlights of the report include:

· The best safety performance in Alcoa's history with more than 99% of Alcoa employees recording no lost work days due to injury.

· Significant progress in contributing to the fight on climate change with a 22.5% reduction of greenhouse gas emissions from 1990 levels - well beyond the targets outlined at Kyoto.

· Reductions in total process water use of 13%, reductions in global sulfur dioxide emissions of 13% and 23% reduction in emissions of nitrogen oxides, all over the past three years.

· Community giving - more than $34 million in 2002 alone - and commitment to an innovative global program designed to deliver "More than Money."

Much of the environmental, social, and economic data in the report have been regularly reported in one form or another by Alcoa for decades, but this is the first time that they have been drawn together to provide an integrated view of the company's performance. This report serves as a complementary volume to Alcoa's 2002 Annual Report.
