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

also reduced its overall emissions by closing and curtailing high-cost,
less efficient facilities as it continued to reshape its commodity
