Alcoa Named to World and North American Dow Jones Sustainability Indexes

September 8, 2011

Company Included in DJSI for Ten Years in a Row

NEW YORK–For the tenth consecutive year, Alcoa (NYSE:AA) has been named to the
Dow Jones Sustainability Indexes (DJSI), one of the most highly
recognized and long-standing global sustainability indexes. Alcoa was
named to both the World and the North American Indexes and was named the
Industry Leader for the Aluminum Sector.

The Dow Jones Sustainability World Index (DJSI World) comprises the
leading companies in terms of sustainability around the world. It
captures the top 10 percent based on long-term economic, environmental
and social criteria out of the world’s largest companies. The Dow Jones
Sustainability North America Index (DJSI North America) captures the
leading 20 percent in terms of sustainability out of the largest North
American companies.

The indexes follow a best-in-class approach and include sustainability
leaders from industries worldwide, serving as an important guide for
investors to assess a company’s sustainability portfolio. 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.

“We’ve spent the last decade as a component of this world-renowned
sustainability index and that is something we are extraordinarily proud
of as a company,” said Kevin Anton, Alcoa’s Vice President and Chief
Sustainability Officer. “By the very nature of aluminum – high strength,
light weight and recyclable – it is a truly sustainable product that
offers significant advantages to our customers.”

The company reported solid progress on its sustainability efforts in
2010 and 2011, including the following:

  • Safety and Health: 82 percent of Alcoa locations worldwide had
    zero lost work day incidents and 48 percent had zero recordable
    injuries in 2010.
  • Products: Developed a new set of aluminum alloys that will make
    airplanes lighter and more efficient while improving durability. These
    technological advancements allow for a 12 percent increase in fuel
    efficiency and provide up to 10 percent in weight savings over
    composite-intensive planes. Launched Reynobond® with
    EcoClean™, the first coil-coated architectural panel that helps clean
    itself and the air around it. It is an economically viable
    self-cleaning technology that reduces maintenance costs and helps with
    the decomposition of smog and other pollutants, from dirt to diesel
    fumes, which cling to building surfaces. In fact, 10,000 square feet
    of Reynobond with EcoClean has the approximate air cleansing power of
    80 trees.
  • Climate Change: Reduced the greenhouse gas footprint of the
    Company’s operations. Alcoa Global Primary Products lowered its CO2
    intensity by 7 percent over 2009 levels and achieved a 22 percent
    reduction over 2005 levels, exceeding the Company’s 2020 goal of a 20
    percent reduction. These reductions are the result of strategic
    efforts to reposition operations to take advantage of clean
    hydroelectric power, quickly share best practices to reduce process
    emission, and drive energy efficiency at every location.
