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.

Direct CO2 intensity of aluminium production, 2000-2017


Emissions intensity of aluminium production must decline

The CO2 intensity of aluminium production remained flat in 2017, as it has since 2014. According to the SDS, however, an annual decline of 1.2% is needed to 2030. Getting on track with the SDS will require improved scrap collection and sorting to enable greater production from scrap, and further development of new technologies to reduce emissions from primary production. Governments can better co‑ordinate aluminium scrap collection and sorting, provide RD&D funding and adopt mandatory CO2 emission reduction policies.
