There was a rapid reduction in fluoride emission intensity in Søderberg aluminum production between 2008 and 2018, a trend which was interrupted by a 2019 increase. Søderberg technology production had a mean emission intensity of around 1.82 kilograms of fluoride emitted per ton of aluminum produced in 2018. By 2020, it had risen to approximately 2.22 kilograms of fluoride per ton of aluminum. Fluoride emissions from primary aluminum production include perfluorocarbons, powerful greenhouse gases, as well as hydrogen fluorides, which are harmful to plants.
