THINK ALUMINIUM THINK AL CIRCLE
Primary aluminium remains one of the most energy-intensive industrial commodities, consuming 13-15 MWh per tonne and accounting for over 900 TWh of electricity demand globally. When powered by coal, production emits 12–14 tonnes of CO₂ per tonne of aluminium, making electricity sourcing (not smelting technology) the decisive factor in determining carbon intensity.
{alcircleadd}On the production front, geography seems to be dictating emissions far more than incremental efficiency gains in cell design. Smelters powered by hydro or nuclear energy, like those in Norway, Quebec, and Iceland, emit as little as 1-2 tonnes of CO₂ per tonne of aluminium produced.
Au contraire, coal-dependent operations across China, India, and Australia routinely exceed 12–16 tonnes. As carbon pricing mechanisms, trade barriers, and procurement standards tighten, aluminium production is increasingly being reshaped by access to low-carbon power and raw material proximity.
