Alcoa Again Named One of the World’s Most Sustainable Corporations at Davos

January 29, 2009

NEW YORK–Alcoa (NYSE:AA) announced today that it was named as one of the most
sustainable corporations in the world in the fifth annual Global 100
ranking of the top role models in sustainable business practices, during
the World Economic Forum in Davos, Switzerland. Alcoa has attained the
sustainability ranking every year since the Global 100 was launched in
2005. Alcoa is the only U.S. based company named to the list from the
Materials sector.

The Global 100 includes companies from 15 countries encompassing all
sectors of the economy. The companies were evaluated on how effectively
they manage environmental, social and governance risks and opportunities
in relation to their industry peers.

This year, the 100 companies were traced back to their year of origin to
see what kind of longevity they have demonstrated in managing
stakeholder relationships. In all, 46 of the 2009 Global 100 companies
have been in existence for at least 100 years.

The list was created by Canadian media company Corporate Knights Inc.
and international investment advisory firm Innovest Strategic Value
Advisors, which specializes in analyzing “non traditional” drivers of
risk and shareholder value.

Alcoa continues to be on the leading edge of sustainable practices.
Alcoa is a proponent of legislation to reduce U.S. greenhouse gas
emissions, and recently joined with fellow members of the U.S. Climate
Action Partnership (USCAP) in launching a climate protection initiative,
called the Blueprint for Legislative Action, which includes
policy recommendations on confronting climate change and supports a U.S.
cap-and-trade program. The company is a founding member of the U.S.
Climate Action Partnership, which is seeking mandatory climate change
legislation, and is a founding reporter of the Climate Registry. In
addition, Alcoa invests in new technologies, such as the groundbreaking
carbon capture technology, which delivers significant greenhouse
benefits by locking up CO2 that is otherwise released into the
atmosphere. In 2007, Alcoa opened its first smelter in 20 years in
Iceland powered by sustainable hydropower, and is currently evaluating
geothermal as a power source for aluminum smelting.
