Advancing Sustainably: Alcoa’s 2050 net zero ambition

The global pressure for climate action is accelerating – and rightly so. The science is clear that global warming due to greenhouse gas (GHG) emissions is a real issue, and solving this challenge requires action by governments, businesses, and society at-large.  

As a company with a 135-year legacy of strong environmental, social, and governance practices, Alcoa is already focused on a decarbonization path. Our smelting portfolio is  powered over 75 percent by renewable energy. We have pursued sustainability-related innovations in bauxite, alumina, and aluminum and are developing game-changing technology innovation that has the potential to fundamentally transform aluminum production. 

But the climate challenge requires substantial action, and that includes continuing to decarbonize materials such as aluminum that will be critical in building a more sustainable future.

So today, Alcoa announced its ambition to achieve net-zero greenhouse gas (GHG) emissions across all our global operations by 2050.

This ambition includes direct (scope 1) and indirect (scope 2) emissions and complements our existing GHG targets, which include reducing direct and indirect GHG emissions from aluminum smelting and alumina refining operations from 2015 baselines by 30% by 2025 and 50% by 2030.

To make progress towards our 2050 ambition, we are focused on further increasing the share of our operations powered by renewable energy and commercializing breakthrough innovation. 

We’re currently piloting mechanical vapor recompression, a renewable energy-powered process that has the potential to significantly reduce alumina refining emissions. And, with our partners, we continue to work toward commercialization of the ELYSIS zero-carbon smelting technology invented by Alcoa, which can eliminate all direct emissions from the aluminum smelting process, producing oxygen instead. 

Looking ahead, our focus will be on continuing to develop these technologies and bring them to market for the benefit of our company and the industry as a whole. 

Alcoa’s ambition to drive toward net-zero is aimed at ultimately helping to create a more sustainable aluminum value chain that enables the low-carbon future.
