Three years ago, members of the International Council on Mining & Minerals (ICMM) committed to implementing GISTM by August 5, 2023, at tailings facilities with the highest potential consequences in the event of a failure. Hydro has successfully implemented GISTM at all tailings facilities with a “very high” consequence classification, located at the Alunorte alumina refinery and Paragominas bauxite mine in the Brazilian state of Pará. None of Hydro’s facilities are classified as “extreme.” 

“For the mining industry, the implementation of GISTM is important for mitigating risks, fostering sustainable operations and building trust. Hydro has delivered on its commitment to implement the standard’s requirements,“ says President and CEO Hilde Merete Aasheim.

GISTM is a robust framework developed to enhance the safety, sustainability, and overall management of tailings facilities in the mining industry. It was launched in August 2020 by the UN Environmental Program (UNEP), PRI (an investor initiative in partnership with UNEP Finance Initiative and UN Global Compact) and the ICMM. Due to ever-changing framework conditions, GISTM represents an ongoing process of continuous improvement with the best available technology, integrated thinking, action, collaboration, and learning. 

“We stay committed to keep our operations in line with current requirements. Our adherence to GISTM demonstrates Hydro’s commitment to continuously pursue best practices, safety, and environmental stewardship,” says Aasheim.

The conformance of each tailings facility has been assessed and confirmed through a self-assessment in line with the GISTM Conformance Protocol. A third-party validation will be undertaken as soon as reasonably practicable.
