Analysis by Guan Dabo at Tsinghua University in Beijing, China, and his colleagues suggests that the total carbon footprint of bitcoin mining in China will peak in 2024, releasing around 130 million metric tonnes of carbon. By 2024, bitcoin mining in China will require 297 terawatt-hours of energy and account for approximately 5.4 per cent of the carbon emissions from generating electricity in the country. "Overall, from all of China's bitcoin mining activity, 40 per cent is powered by coal." Given China's commitment to a 2060 net-zero carbon goal, regulations to reduce carbon emissions from bitcoin mining and future emergent sectors will need to be implemented, he says.	./cache/www-newscientist-com-9057.html	./txt/www-newscientist-com-9057.txt
