Environment, Health and Safety

Environment, health and safety (EHS) are the 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

From a 2015 baseline, reduce our greenhouse gas footprint (direct and indirect emissions) from our smelting operations by 15 percent by 2025 and 20 percent by 2030.


Define and implement a program focused on enhancing water-use efficiency at locations in water-scarce areas by 2020; define specific water-use reduction targets for 2025 and 2030.


Optimize our portfolio of economically viable placement opportunities for byproduct materials (from waste to value) by 2020; define specific objectives to be achieved by 2025 and 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).
