The Environmental Cost of CryptoArt (via densediscovery.com).

(…) the average NFT has a footprint of around 211 kg of CO2 equivalent. That's the same as an EU resident's electric power consumption for more than a month, driving for 1000km, or a return flight from London to Rome. And that's just for keeping track of who owns it - it doesn't include the energy consumption used in the creation of the work, its storage, or the website it's hosted on.
