China's aluminum industry is heading for a massive transition. China makes most of the world's aluminum, largely using coalfired electricity. The sector singlehandedly creates about 5% of China's carbon emissions. To meet the country's climate goals, producers will need to rebuild plants close to renewable energy sources. SP Global Ratings expects the transformation to be increasingly ...

One tonne of aluminum generates between five and 25 tonnes of CO 2, depending on its source of electricity, according to Mineralinfo, a resource portal run by the French government. Emissions depend above all on the type of fuel used—often coal or heavy fuel oil—to produce the vast quantities of energy necessary to make the metal.
