Carbon emissions per tonne of primary aluminum production have been decreasing from 2012 to 2021. After Paris Agreement in 2015, carbon emissions decreased by about 6.4% compared to last year. One of the reasons of this deduction in aluminum sector is the use of modern technology.
The largest share of carbon emission in the primary aluminum production process is allocated to electricity. The share of electricity in this process was about 64.5% in 2021. And the reason for this large share is used of sources like coal which emits significantly greenhouse gases.
