Alcoa Named One of the Most Sustainable Corporations in the World for the Third Consecutive Year

Alcoa (NYSE:AA) announced today that it has been named one of the

row. Alcoa was recognized among the top role models in sustainable
business practices in the annual Global 100 Most Sustainable

Chairman and CEO Alain Belda. "We incorporate sustainable behavior
into our business practices, partnerships and community engagement. At
Alcoa, we view sustainability as the simultaneous achievement of
financial success, environmental excellence and social responsibility,
which delivers long-term benefits to our stakeholders. Receiving this
recognition adds momentum to our corporate sustainability
initiatives," Belda said.
