Climate Protection

Building upon our strong leadership in reducing GHG emissions within the aluminum industry, we have set an ambition to achieve net-zero GHG emissions across our global operations by 2050 for direct (scope 1) and indirect (scope 2) emissions.

Our path to achieving this ambition includes increasing the use of renewable energy in our operations, portfolio decarbonization, and developing new technologies that are important to unlocking decarbonization at scale and bringing them to the market over time. Carbon dioxide represents most of our GHG emissions.

Our endeavor to reach net-zero GHG emissions by 2050 for direct and indirect emissions aligns with our strategic priority to advance sustainably. It also complements our short- and mid-term GHG reduction targets.

Introduced in 2020, our short- and mid-term goals align our GHG (direct + indirect) emissions reduction targets with the below 2º C decarbonization path defined in the Paris Climate Accord. We are committed to reducing our GHG emission intensity by 30 percent by 2025 and 50 percent by 2030 from a 2015 baseline. We achieved a 23.9 percent reduction from the baseline through 2021. Our total 2021 carbon dioxide equivalent (CO2e) emissions equaled 21.8 million metric tons, of which 17.4 million metric tons were direct emissions. This represents a 9.1 percent decrease in total emissions and a 10.7 percent decline in intensity compared to 2020. The decreases were primarily driven by the curtailment of the Intalco smelter and a continued focus on operational stability and optimization.
