Alcoa Reduces Greenhouse Gases by 23 Percent from 2005 Baseline

Alcoa (NYSE:AA) published its 2012
Sustainability Report, detailing the Company's global environmental,
social and economic performance during 2012. Alcoa has produced the
report for 11 consecutive years.

'The truest validation of our sustainability as a company comes from our
stakeholders and society at large,' said Alcoa Chairman and CEO Klaus
Kleinfeld. 'Our miracle metal, aluminum, is an essential material for a
sustainable global system that many societies and businesses are
striving toward. We continue to show that the value of aluminum?its
light weight, non-corrosive nature, and infinite recyclability, to name
a few traits?significantly outweighs the impacts of its production.'

• 
  Reduced annual greenhouse gases by 23 percent since 2005.
  
• 
  Included in the Dow Jones Sustainability Indexes for the 11th
  consecutive year.

  important health issues for employees.

  in their communities.
  
• 
  Executed and delivered on 2012 financial targets despite an extremely
  challenging environment, especially with respect to primary aluminum,
  which had a London Metal Exchange average price of US$2,019 during the
  year.
