Three U.S. lawmakers introduced a bill that would ask the Environmental Protection Agency to study crypto mining activity and require that miners that use more than 5 megawatts of power submit information on their greenhouse gas emissions.
Sens. Ed Markey, D-Mass., and Jeff Merkley, D-Ore., and Rep. Jared Huffman, D-Calif., sponsored the legislation, dubbed the "Crypto-Asset Environmental Transparency Act." The lawmakers say the oversight is needed for the U.S. to achieve its sustainability targets by the end of the decade, and it's been endorsed by the Sierra Club, Earthjustice, Environmental Working Group and Seneca Lake Guardian.
"This bill is an important step to understanding the full environmental impacts of these operations, as well as holding crypto mining operations accountable for the damage they cause," Merkley said in a statement.
The lawmakers said that Bitcoin mining carbon emissions will reach to 21-35 megatons in 2022, comparable to driving 4.5 million-7.5 million cars for one year. If approved, results would be given to committees at Congress as well as posted for the public on the EPA and Department of Energy websites.
