I just found this last night: https://github.com/memo/eco-nft. From the README: > Selling work on a blockchain can be a technically challenging task. For this reason, many platforms and websites have emerged, aiming to make this process as seamless and easy as possible for artists. Unfortunately, currently many of these websites are based on the Ethereum blockchain, which is very inefficient and ecologically costly by design. E.g. selling just a single-edition artwork on Ethereum has a carbon footprint starting at around 100 KgCO2, which is equivalent to a 1 hour flight (and depending on the platform, can reach a long-haul flight) [2]. Selling an edition of 100 works has a carbon footprint of over 10 tonnes CO2, which is more than the per capita annual footprint of someone in the EU - including all emissions from industry and trade [3].
