Company Named in the DJSI for the Eleventh Consecutive Year

NEW YORK–For the eleventh consecutive year, Alcoa (NYSE:AA) has been named to one
of the most highly recognized and longest-standing global sustainability
indexes, the Dow Jones Sustainability Indexes (DJSI). Alcoa was
recognized as the global aluminum industry sustainability leader as well
as the North America leader in the aluminum sector.

“Alcoa’s commitment to not just meeting but exceeding the industry
standard for economic, environmental and social responsibilities is a
long-standing priority of this company,” said Kevin Anton, Alcoa Vice
President and Chief Sustainability Officer. “Sustainability is a part of
everything we do, from the way we run our operations, to the innovative
material solutions that we are bringing to the world; making
transportation more fuel efficient, buildings greener, packaging
infinitely recyclable, and consumer electronics lighter and less energy
intensive. We are honored to have been named to this world-renowned
sustainability index for the last 11 years.”

The Dow Jones Sustainability World Index (DJSI World) includes the top
10 percent of the largest 2,500 companies in the Dow Jones Global Total
Stock Market Index. The Dow Jones Sustainability North America Index
(DJSI North America) comprises the top 20 percent of the 600 largest
companies from Canada and the United States.

The company improved on its year-over-year score in all three Dow Jones
key dimensions – Economic, Environmental and Social. Performance
highlights include:

• Economic: Integrated sustainability metrics into our supplier
  assessment process to drive a more sustainable supply chain.
• Environmental: Achieved a 23% improvement in greenhouse gas
  (GHG) intensity in the Alcoa Global Primary Products business between
  2005 and 2011, surpassing the Company’s 2020 target of a 20%
  improvement. In light of this, the Company set a new goal to achieve a
  30% GHG intensity improvement by 2020 and a 35% improvement by 2030,
  from a 2005 baseline.

  community programs in 2011, and a record 56% of Alcoa employees
  volunteered in their communities during Alcoa’s 2011 Worldwide Month
  of Service.

The Dow Jones Sustainability Indexes are made up of global, regional and
country industry leaders in terms of sustainability. Selection to the
DJSI is based on an in-depth analysis of a company’s economic,
environmental and social aspects with a focus on long-term development
of corporate value. The benchmarks set by the indexes allow investors to
use them as an important guide when assessing a company’s sustainability
portfolio.
