American media artist Kyle McDonald announces Amends (2022), a project mitigating NFT marketplace emissions. Once Ethereum abandons the energy-intensive proof-of-work consensus mechanism, three digital sculptures (CGI by Robert Hodgkin) will be auctioned on Open Sea, Rarible, and Foundation. Priced at $17 million total (and rising), proceeds will go to air and ocean carbon capture projects. Owners can exchange their digital sculpture for a physical one—if they burn their NFT.
