Aren't NFTs bad for the environment? It is a very good and complex question! In a nutshell,
Ethereum-based NFTs are currently using the infrastructure which is very energy-inefficient, and
probably increasing its popularity and associated emissions to some extent. There are other
types of blockchains which are much more energy-efficient (they are using Proof-of-Stake
principle, PoS). NFTs minted there are not associated with excessive carbon footprint. Ethereum
is expected to switch to Proof-of-Stake in 2021 or 2022. More detailed discussion (and many
links) can be found in our positioning paper
