This is the best summary I could come up with:

Tens of thousands of NFTs that were once deemed the newest rage in tech and dragged in celebrities, artists and even Melania Trump have now been declared virtually worthless.

NFTs, or non-fungible tokens, are a form of crypto asset that is used to certify ownership and authenticity of a digital file including an image, video or text.

The report comes nearly two years after the craze for NFTs swept up celebrities and artists alike, with many rushing to purchase NFT collections of the Bored Ape Yacht Club and Matrix avatars.

The drastic downward market shift surrounding such crypto assets “underscores the need for careful due diligence before making any purchases, especially one of high value”, the report said.

Researchers identified 195,699 NFT collections with no apparent owners or market share and found that the energy required to mint the NFTs was comparable to 27,789,258 kWh, resulting in an emission of approximately 16,243 metric tons of CO2.

In order to survive market downturns and have lasting value, NFTs need to be either historically relevant such as first-edition Pokémon cards, true art or provide genuine utility, they said in the report.
