Aluminium industry reports decline in greenhouse gas emissions

February 28, 2024

New data from the International Aluminium Institute (IAI) reveals that, for the first time, total greenhouse gas emissions from the global aluminium sector did not grow, even though aluminium production grew.

The 2022 data, the latest available, shows aluminium production grew by 3.9% from 104.1 million tonnes to 108.2 million tonnes. However, greenhouse gas emissions from the industry showed a slight decline from 1.13 giga-tonnes CO2e to 1.11 giga-tonnes CO2e, and the GHG emissions intensity of primary aluminium production (the average quantity of emissions from the production of a tonne of primary aluminium) has been declining since 2019. In 2022, intensity declined by 4.4% from 15.8 tonnes CO2e per tonne to 15.1 tonnes CO2e per tonne.
