Alcoa Cuts Emissions, Adds RE

Alcoa made strides in improving its environmental footprint, including achieving a 9.1% decrease in carbon dioxide equivalent emissions and a 15.4% decrease in landfilled waste in 2021

By the end of 2021, 81% of electricity consumed by Alcoa’s aluminum smelters was from renewable sources.

Alcoa continued to accelerate the development of breakthrough innovations that have the potential to decarbonize significant portions of the aluminum value chain, which includes the ELYSIS™ zero-carbon smelting JV, the Refinery of the Future initiative and the company's ASTRAEA™ recycling process.

The company reported details of its emissions progress in its 2021 sustainability report.

Alcoa continued to enable the growing low-carbon aluminum market through its Sustana™ brand, the industry’s most comprehensive portfolio of low-carbon products, including through a deal to supply a mix of low-carbon EcoLum™ metal and metal from the ELYSIS joint venture for the wheels on Audi’s e-tron GT electric sportscar.

The company made progress in investigating new products that can help support the low-carbon transition, including a joint development project to investigate the production of high-purity alumina (HPA), which is used in LED lighting and lithium-ion batteries.

“Now, more than ever, our world needs reinvention, and we made significant progress in 2021 against our vision to reinvent the aluminum industry for a sustainable future,” said Roy Harvey, Alcoa President and CEO, in a statement. “This year’s sustainability report outlines how we are leveraging our processes, products, and people to help usher the aluminum industry into the low-carbon future and work with stakeholders across the value chain to build a better world.”
