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

September 16, 2015

For the fourteenth 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 prestigious 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.

“Sustainability guides everything we do, from creating innovative
solutions that help de-carbonize our world and create value for
customers, to improving the sustainability of our own manufacturing
processes, said Kevin McKnight, Alcoa’s Chief
Sustainability Officer and Vice President of Environment, Health and
Safety. “The progress we continue to make demonstrates that we live our
sustainability value every day, with a goal of leaving a positive impact
everywhere we operate and in every market where we compete.”

Over the last year, Alcoa expanded its multi-material value-add
portfolio and introduced innovations across its end markets enabling
customers to produce more environmentally friendly products. The Company
also reduced its overall emissions by closing and curtailing high-cost,
less efficient facilities as it continued to reshape its commodity
business.

Highlights of Alcoa’s industry-leading sustainability performance
include:

  • Reduced absolute greenhouse gas emissions by 3 million metric tons, or
    6.8 percent
  • Developed forging for the world’s first hybrid-metallic fan blade,
    helping make Pratt & Whitney’s PurePower® engines
    lighter and more fuel efficient
  • Unveiled Alcoa MicromillTM technology; will manufacture
    most advanced aluminum sheet on the market, supporting the creation of
    lighter, more fuel efficient, safer vehicles
  • Introduced Ultra ONETM heavy-duty truck wheel; 47 percent
    lighter than steel wheel of same size, enables trucks to increase fuel
    efficiency and payload
  • Named the World’s Most Active Organization by the Global Corporate
    Challenge for the second consecutive year
  • Invested US$38.4 million in community programs via Alcoa and Alcoa
    Foundation
