Environment, Health and Safety

Environment, health and safety (EHS) and regulatory compliance are key cornerstones of our sustainability commitment. Innovative programs in EHS have made us leaders in emissions and energy management, resource conservation, mine rehabilitation and workplace safety.

Our performance is driven by—and measured against—the following strategic long-term goals.

Emissions and Energy

Align our GHG (direct + indirect) emissions reduction targets with the below 2º C decarbonization path by reducing GHG emission intensity by 30 percent by 2025 and 50 percent by 2030 from a 2015 baseline.


From a 2015 baseline, reduce the intensity of our total water use from Alcoa-defined water-scarce locations by 5 percent by 2025 and 10 percent by 2030.


From a 2015 baseline, reduce landfilled waste by 15 percent by 2025 and 25 percent by 2030.

Bauxite Residue

From a 2015 baseline, reduce bauxite residue land requirements per metric ton of alumina produced by 15 percent by 2030.

Mine Rehabilitation

Maintain a corporate-wide running five-year average ratio of 1:1 or better for active mining disturbance (excluding long-term infrastructure) to mine rehabilitation.

Health and Safety

Zero fatalities and serious injuries (life-threatening or life-altering injuries and illnesses).
