Bitcoin mining’s carbon emissions have increased after moving from China to the United States and other countries, according to a team of academics from the Netherlands, Switzerland, and Germany.
The group states in a research published in the journal Joule that, as Bitcoin miners have been forced out of China, they have relocated to areas with fossil-fuel-based electrical sources, resulting in increased carbon dioxide emissions. They estimated that, after mining farms relocating to other nations, the carbon intensity of Bitcoin increased by about 17%.
