The Copper Mark, an assurance framework to promote responsible practices in the copper mining industry, has signed a memorandum of understanding (MoU) to integrate its assurance status with the CRU Group's Emissions Analysis Tool.

In a statement, the Copper Mark described the CRU Emissions Analysis Tool as a digital platform that compares emissions across global value chains.

The tool compares asset-level sustainability data, which will now include an acknowledgement that a copper site has received the Copper Mark - meeting its standards on quantifying, lowering, and reporting on GHG emissions.

The MoU between the Copper Mark and the CRU Group will help to further embed transparency around emissions from global copper value chains, enhancing accountability and raising the importance of measuring, reducing, and reporting on emissions throughout the supply chain.

Michèle Brülhart, executive director of the Copper Mark, described the MoU as essential in promoting transparency around emissions linked to copper supply chains.

"Understanding and mitigating the copper value chain's carbon emissions form a key part of the Copper Mark's mission to promote responsible production and sourcing practices throughout the industry," Brülhart said.

Lavan Mahadeva, CRU's research director, added: "CRU's Emissions Analysis Tool reveals that copper mines, smelters, and refineries display interesting differences in their carbon emissions' intensities.

"But a holistic assessment of responsible copper production should also take in other important environmental and social aspects."
