One of the world’s biggest gold refineries will look to stop sourcing metal from mines that fail to meet standards on carbon emissions.

MKS PAMP SA plans to curb emissions that come from its supply chain by 27.5% before the end of the decade, the company said in a statement Wednesday. As a result the Geneva-based firm may have to refuse gold from mines that create too much carbon dioxide.
