NEW YORK–Alcoa (NYSE:AA) announced today that it is among 60 corporations pilot
testing a draft protocol for accounting and reporting greenhouse gas
(GHG) emissions across a product’s life cycle. The Greenhouse Gas
Protocol Initiative is being launched by the World Resources Institute
(WRI) and the World Business Council for Sustainable Development (WBCSD).

WRI and WBCSD have developed two new GHG Protocol standards, the Product
Life Cycle Accounting and Report Standard and the Scope 3 (Corporate
Value Chain) Accounting and Reporting Standard. Alcoa will test the
Product Standard by measuring the climate change impact of its aluminum
forged wheels.

“We are pleased to participate in the evaluation of this new standard
and anticipate the results will allow us to better calculate and
communicate the impacts of our products on climate change. We feel the
forged wheel would be an excellent study, as it is a product which
provides sustainability benefits by reducing fuel consumption and
greenhouse gas emissions through its usage,” said Tim Myers, President,
Alcoa Wheel and Transportation Products.

The road testing process will provide real-world feedback to ensure the
standards can be practically implemented by companies from a variety of
sectors, sizes and geographic areas around the world. Companies
participating in the road testing represent 17 countries from every
continent and more than 20 industry sectors. Alcoa’s learnings from the
multi-month evaluation and results will contribute to publication of
final standards in late 2010.
