Alcoa Named Sustainability Leader on Dow Jones Indices for Fifteenth Consecutive Year

September 12, 2016

Company was once again recognized as aluminum industry leader

For the fifteenth year in a row, lightweight metals leader Alcoa
(NYSE:AA) has been named as one of the world’s leading companies for
sustainability on the Dow Jones Sustainability Indices (DJSI) — a
globally recognized and reputable benchmark for corporate responsibility
and sustainability. Alcoa was again recognized as the Aluminum Industry
Leader on the Dow Jones World Index.

“As we prepare to launch two strong companies in the second half of
2016, we will continue using our innovation, creativity, and passion to
deliver net-positive benefits to the environment, communities where we
operate, our employees, and our shareholders,” said Kevin McKnight,
Chief Sustainability Officer and Vice President, Environment, Health &
Safety.

Highlights of Alcoa’s 2015 sustainability performance include:

  • Achieving 2020 greenhouse gas intensity target five years ahead of
    plan by reducing absolute greenhouse gas emissions by 5.5 million
    metric tons and improving our greenhouse gas emission intensity by
    31.3% from our 2005 baseline.
  • Became one of the first companies to sign the American
    Business Act on Climate Pledge
    . As part of that pledge, committing
    to reduce absolute U.S. greenhouse gas emissions by 50% versus a 2005
    baseline and also demonstrate a net reduction of greenhouse gas
    emissions from the use of products equal to three times the emissions
    created by their production—all by 2025.
  • Alcoa-developed high-performance aluminum, titanium, and nickel-based
    alloy products are found from nose to tail on every high-growth
    commercial aircraft platform. These products produce lighter, more
    fuel-efficient planes with highly efficient engines and smaller carbon
    footprints.
  • Alcoa Micromill® material, which produces automotive parts that are
    twice as formable and 30 percent lighter than parts made from
    high-strength steel, debuted on the 2016 Ford F-150 truck.
  • During 2015, improved bauxite residue storage efficiency and
    rehabilitation rate. In addition, finalized biodiversity action plans
    for three locations, and minimized global mining footprint.
