“Sustainability is part of everything we do.” Alcoa Chairman and CEO
Klaus Kleinfeld

NEW YORK–Alcoa (NYSE:AA) today published its 2011
Sustainability Report which details the company’s global
environmental, social and economic performance. It is the 11th
year in a row Alcoa has produced the report.

“Sustainability is not a catalog of processes, nor merely a philosophy
at Alcoa,” said Chairman and CEO Klaus Kleinfeld. “Rather, it is part of
everything we do.”

Alcoa businesses use a Sustainability Scorecard to align sustainability
targets with business strategy and provide a dashboard to measure
progress against key near-term sustainability metrics. In addition, each
Alcoa business has developed a roadmap to lay out process steps,
decisions, and technical improvements needed to realize longer-term
objectives.

In addition, Alcoa links pay for performance and sustainability goals.
During 2011, 20 percent of variable compensation was tied to achieving
significant aspects of sustainability targets.

Significant achievements highlighted in the report include:

• The introduction of Reynobond® with EcoClean™, the first coil-coated
  architectural panel that helps clean itself and the air around it.
• For the first time in a calendar year, Alcoa had zero employee
  fatalities.
• Alcoa’s Global Primary Products business reduced its total carbon
  dioxide intensity by 23 percent and the company as a whole decreased
  its global freshwater-use intensity by 21 percent between 2005 and
  2011, exceeding both of these 2020 targets and allowing us to bring
  the company’s 2030 goals in both areas forward to 2020.
