"One Bitcoin transaction would generate the CO2 equivalent to 706,765 swipes of a Visa credit card," Another way to look at it: Bitcoin uses over 0.5% of the world's electricity: https://interestingengineering.com/why-bitcoin-mining-consumes-more-electricity-than-entire-countries https://interestingengineering.com/why-bitcoin-mining-consum... With that, Bitcoin does about 300,000 transactions a day. https://www.statista.com/statistics/730806/daily-number-of-bitcoin-transactions/ https://www.statista.com/statistics/730806/daily-number-of-b... But there are over a billion daily credit card transactions alone - 3000 times as much. So if each credit card transaction were replaced by a Bitcoin transaction, we'd use 30 times as much electricity as the entire planet produces. --- These numbers are so grossly lopsided and so widely bandied about that when I hear someone say, "I have yet to hear anyone make an analysis of the environmental cost" I think, "Perhaps you don't want to hear it."
