Compared to crypto?

  Back of the envelope, they're roughly the same, CO2-wise.

    I doubt that

      US junk mail volume is something in the 6 million ton range, and paper production releases 3-10 pounds of CO2 / pound of paper, depending on whether it is virgin or recycled. (Regoogling that second figure returns some ranges as low as 1-2 lb/lb, which would put junk mail at like 0.2-0.4 crypto.)

        Your co2 from crypto number seems low. Is that perhaps just bitcoin?
        • saalweachter 4y ago
          Possibly 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.
