Aluminium

Aluminium production is highly energy-intensive, with electricity making up a large share of the energy consumed. Given the high level of electricity consumed in the aluminium subsector, power sector decarbonisation is a key complement to emissions reduction efforts in aluminium.

Emissions intensity of aluminium production must decline

The direct CO2 intensity of aluminium production remained relatively flat during the past couple of years. In the Net Zero Emissions by 2050 Scenario, however, emissions intensity declines 3% annually to 2030. Getting on track with this scenario will require improved end-of-life scrap collection and sorting to enable greater production from scrap and further development of new technologies to reduce emissions from primary production. Governments can stimulate action by better coordinating aluminium scrap collection and sorting, funding RD&D and adopting mandatory CO2 emissions reduction policies.
