Sustainability at Alcoa

Advancing sustainably

We extract, process, and refine the most recyclable mineral on earth. And the aluminum we produce plays a key role in meeting the needs of a sustainable society. We are proud of our commitment to excellence in environmental, social and governance practices. We have been recognized as a leader in sustainability from the Dow Jones Sustainability Indices, and we’ve earned certifications from Aluminum Stewardship Initiative (ASI), the industry’s most comprehensive system to verify responsible production.

Our ambition to reach net-zero greenhouse emissions by 2050 across our global operations complements our existing environmental targets that includes reducing direct and indirect emissions. We are developing new technologies that will help us unlock decarbonization at scale.

Improving Our Footprint

Exploring our path toward net zero

Alcoa’s ambition to drive toward net-zero is aimed at ultimately helping to create a more sustainable aluminum value chain that enables a low-carbon future. We intend to continue the development of game-changing technologies, including the ELYSISTM zero-carbon smelting process and creating a Refinery of the Future that could use mechanical vapor recompression (MVR) and electric calcination to reduce emissions in the alumina refining process.

Alcoa invented the inert anode technology for aluminum smelting that serves as the basis for the ELYSIS joint venture. This technology emits pure oxygen and eliminates GHG emissions associated with the traditional process to make molten aluminum.
