For the thirteenth year in a row, 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 again
recognized as the Aluminum Industry Leader on the Dow Jones World Index.

“Sustainability is a core Value at Alcoa. No decision is made or action
taken without a careful consideration of the economic, environmental,
and social impacts that may result,” said Kevin McKnight, Alcoa Chief
Sustainability Officer and Vice President of Environment, Health and
Safety. “In 2013, we worked more safely with fewer environmental
impacts. While we’re continuing to improve the sustainability of our
global operations, our light-metal innovations are creating a more
sustainable world by enabling greener cars and trucks, more fuel
efficient airplanes and more energy-efficient buildings.”

Earlier this year, Alcoa announced that 2013 was its safest, most
environmentally-efficient year on record. Highlights of Alcoa’s
sustainability performance include:

• Safest year on record, with no employee fatalities and a 30 percent
  reduction in workplace injury rate
• Reduced greenhouse gas emissions intensity by 25.5 percent from the
  2005 baseline, and lowered absolute emissions by 3.1 million metric
  tons
• Introduced breakthrough bonding technology to enable
  aluminum-intensive vehicles that are lighter and more fuel-efficient
• Invested US$40.9 million in community programs through Alcoa and Alcoa
  Foundation
• 37,200 employees, or 62 percent, volunteered in their communities
  during a Worldwide Month of Service
