TL;DR Mint and sell your NFTs on a Tezos based marketplace to minimize emissions

Are NFTs really bad for the environment?

There’s been a lot of news about how minting and selling NFTs is terrible for the environment. Most NFTs are minted and sold on marketplaces using the Ethereum blockchain. It’s estimated that Ethereum requires 36TWh of electricity a year to run. This is roughly 17 million tons of C02 a year. This sounds like a lot but a few things to keep in mind:

  1. This assumes that only fossil fuels are used to create the electricity.
  2. 17 million tons a year is miniscule relative to our planet scale emissions is 51 gigatons per Bill Gates’ excellent book “How to Avoid a Climate Disaster.”
  3. And, a study by the University of Cambridge found that additional blockchain activity doesn’t increase emissions.

But, we shouldn’t ignore the additionality of carbon based on NFT and blockchain activity and as a new NFT artist, you can do something about it.

There’s lots of great articles covering the technical aspects of the difference between Proof of Work…
