Aluminium production is an energy intensive process accounting for around 2% of global GHG emissions. China accounts for the lion share of global primary aluminium production currently standing at 60%. 

The full decarbonisation of the aluminium sector in China could remove 5% of the country’s total GHG emissions.

Emissions from aluminium production largely emerge from the smelting process which depends heavily on coal fired power. In China, this is not only about coal power leading the grid electricity mix but the use of captive coal power plants that power the aluminium industry in coal rich regions.
