Alcoa (NYSE:AA) announced today that it has been named to the Carbon Disclosure Project (CDP) Carbon Disclosure Leadership Index for the sixth consecutive year. This index, a key component of CDP's annual Global 500 Report, highlights companies within the FTSE Global 500 Index that have displayed the most proficient approach to corporate governance in regards to climate change disclosure practices.

The CDP represents 385 global institutional investors with $57 trillion in assets under management. Carbon disclosure and climate change reporting is critical for investors to fully assess their risks, liabilities and opportunities within their portfolios.

The Climate Disclosure Leadership Index is comprised of 67 global 500 companies that showed distinction in their responses to the CDP survey based on reporting of greenhouse gas emissions, emissions reduction targets and risks and opportunities associated with climate change. The index, which provides an evaluation tool for institutional investors, is made up of the top 34 companies selected from non-carbon-intensive sectors and the top 33 companies selected from carbon-intensive sectors.

"Alcoa is committed to address climate change responsibly and sustainably, and we are pleased to be a member of this prestigious honor roll of global corporations addressing the challenges of climate change," said Alcoa President and CEO Klaus Kleinfeld.
