Mining operations account for some 4%-7% of global greenhouse gas emissions, according to global consulting firm McKinsey & Company. But some miners are moving to reduce use of fossil fuels in extracting and refining, partly due to pressure from downstream customers that want more sustainable supply chains. Located beside a crystal-blue lake in the lush jungle of Sorowako, South Sulawesi, Vale Indonesia — a subsidiary of Vale international — runs its smelters entirely from hydroelectricity. Other companies and countries around the world also are reducing use of fossil fuels in their mining operations. But now, having that infrastructure means big savings at a time when global energy prices are high.
