For the fourth year in a row, Alcoa (NYSE:AA) has been named one of Brazil's model companies for sustainable development, in Exame Magazine's Sustainability Guide 2012, the country's largest and most respected publication on sustainability practices and corporate responsibility. The annual guide selects and recognizes the sustainable actions of 20 model companies every year and is Brazil´s most prestigious annual survey on corporate social responsibility. "For Alcoa, it makes us proud to be part of such a select group of companies. This work exemplifies the commitment our employees have to sustainable development," said Frank Feder, Regional CEO, Alcoa Latin America & Caribbean. Alcoa was recognized for replacing fuel oil with natural gas at the Poços de Caldas alumina refinery, a cost effective solution that also resulted in an 11 percent reduction of CO2 emissions at the plant.

The ranking of the Exame Guide is coordinated by the Getúlio Vargas Foundation's Center for Studies in Sustainability, which evaluates companies on three dimensions of sustainability: environmental responsibility, economic success, and social commitment. It also examines business practices, transparency, and corporate governance.
