Crypto Carbon Footprint List
The list below outlines how sustainable each of the top 100+ cryptocurrencies are, where True Green is the most sustainable and Brown is the least sustainable. The cryptos are ranked in order of how sustainable they are.
For ease of comparison, a VISA-transaction is equivalent to Medium Green, as it consumes approximately 0.003 kWh per transaction (0.4 grams of CO2e). The researchers do however acknowledge that many cryptocurrencies – contrary to VISA-transactions - function as value storage and is peer-to-peer rather than executed through multiple intermediaries.
The list has been developed by Cryptowisser.com in collaboration with a team lead by the Swedish sustainability expert Erik Florman, founder of Cleanblocks.com. Background information on cryptocurrency energy consumption, assumptions and qualifications for the report, and further details on how the data has been compiled and what metrics that constitute which grades etc., can be found at the bottom of this page. The aim is to update the below list on a monthly basis.
