### About  
Aluminium is responsible for 4% of global emissions, twice as much as flying. Carbon intensity varies hugely, from 4 to 20 tonnes CO2 per tonne aluminium. CarbonChain tracks carbon from bauxite mining, through alumina refining, to smelting.

#### CarbonChain provides product footprints for the world's 3,000+ aluminium supply chains.
