- saalweachter 4y agoPossibly but the error bars on all of the numbers I'm using are also large, and the age of the numbers matters as well. I find numbers for Bitcoin -- in the same window -- of 30-90 megatons of CO2, for Ethereum of 15-50 megatons, and the figures for junk mail range from 6 to 60 megatons. The error bars all overlap, so the closest I can do with the level of work I'm willing to put in is that junk mail might be a little bit more CO2 than cryptocurrency (or twice as much as Bitcoin), or like 5% of cryptocurrency at the other extreme.
