Non-fungible-tokens (NFTs), which are individual components of crypto artwork, are at least partly responsible for the thousands of tons of planet-warming carbon emissions produced by the cryptocurrency used to purchase and trade them.

Some creators, especially those that have already profited from the fad, believe it is a simple problem to address, and others believe the recommended solutions are unrealistic.


An NFT is a one-of-a-kind cryptocurrency token that can be anything digital, including art, GIFs, and even CEO of Twitter Jack Dorsey’s maiden tweet.

There were some preliminary estimations of just how much electricity an NFT consumes and, as a result, how much global warming pollution it produces.

NFTs and their cryptocurrencies counterparts have one thing in common: they both consume a lot of energy.

Bitcoin mining currently emits 38 million tonnes of CO2 annually, more than Kazakhstan’s carbon footprint.

According to a 2018 report published in Science Climate Change, Bitcoins emissions alone may boost Earth’s climate by 2 °.

Why Bitcoin Consume So Much Energy?

“Bitcoin is a proof of work blockchain, which means it secures the blockchain & verifies transactions using proof-of-work (PoW) confirmation procedures. According to Suzanne Köhler, a Doctorate fellow & sustainable blockchain tech researcher in Denmark, “P-o-W implies that miners fight against one another to generate a block.”

“To succeed in these challenges, specialised computers create billions of guesses every second.” It’s what you’d term a “brute-force” tactic. It’s what necessitates a significant amount of electricity.”

To put this in perspective, Bitcoin’s daily carbon emissions is sort of like watching 57,000 hrs of Videos online. It also utilises the same amount of energy daily that an ordinary American home uses in 25 days.

NFTs have a similar impact on the environment because they require electricity computer operations to verify and trade the art.

Nfts Also Have Same Consumtion

“To generate NFTs, to auction, to repay for the NFT upon winning, or to hand over control, transaction on a blockchain are required,” Köhler explains.

“So you might link the volume of transactions for NFTs will require the same amount of electricity, as well as their global imprint.” The connected impact of NFTs grows as interest in them increases, and more individuals buy & sell them.”

Miners are often driven to use inexpensive electricity to maximise profits, according to Köhler. Therefore the energy needed for these operations is also a concern.

Then there is also the issue of the technology utilised: “Hardware creation & recycling only accounts for a small percentage,” she adds. “However, employing specialist systems for mining, which become unproductive in a matter of years, generates a lot of e-waste.”

Sustainable NFT?

While it’s evident that NFTs have such a significant environmental impact right now, Köhler believes there are still some ways to make them environmentally sustainable in the coming future.

Begin by decreasing the effect of the blockchain that is currently in use.

“The majority of NFTs run on Ethereum, turn on proof-of-work blockchain.

To safeguard their blockchain & verify transactions, Ethereum is switching from proof of work to proof of stake, which will make NFT more viable,” she explains.

“Unfortunately, it is not a simple task and will take time.” This might also be addressed by using a new (non-PoW) blockchain.

Second Option for Sustainable NFT

A second option for NFTs to become even more viable is to reduce the number of blockchain transactions they require. “It can be accomplished by constructing on ‘layer 2,’

which means that not every transaction needed to be recorded on the ledger,” Köhler explains.

“An auctions, for instance, may be held off-chain under layer two but then published to the blockchain in phases. This is a solution which can be implemented more quickly.”

Conclusion of Non Fungible Tokens Environmental Impact- Environmental Footprint

However, sceptics argue that, in a society where coal and oil still account for most energy generation, cryptocurrency & NFTs will remain to contribute to climate change unless action is taken soon.
