In 2021, the electrolysis process released 863 million tonnes of carbon dioxide into the air. In the last three years, this procedure has been the primary emitter in the global aluminum sector and has increased gradually throughout the years. Refining was the second process with the largest CO2 emissions, at 179 million tons.
