CleanNFTs is a phrase that a community of over 3,000 artists from around the world use to describe NFTs from platforms offering Proof of Stake cryptocurrencies. In early 2021 a group of artists and members of the NFT community joined together on Discord to discuss the issues with Ethereum (using Proof of Work) energy usage and since then have been working towards educating, raising awareness and looking at ways to improve the environmental impacts of releasing NFTs. 


In September 2022 Ethereum transitioned to Proof of Stake
