Despite the fact that NFTs themselves have no environmental impact, the impact on our climate is related to how an NFT is produced, because the process of producing NFTs is highly energy-intensive.

The majority of NFTs are created using the Proof of Work (PoW – describes a system that necessitates a significant but manageable amount of effort to discourage frivolous or malicious uses of computing power, such as sending spam emails or launching denial of service attacks. Hal Finney later adapted the concept to secure digital money in 2004) operating method, which requires a significant amount of electricity. Any energy-intensive process, crypto-related or otherwise, can exacerbate climate change by increasing carbon dioxide emissions into the atmosphere. There are, however, more environmentally friendly methods of minting NFTs, particularly methods based on Proof of Stake (PoS). Proof of Stake protocols are a class of consensus mechanisms for blockchains that work by selecting validators in proportion to their quantity of holdings in the associated cryptocurrency. This is done to avoid the computational cost of proof of work schemes.

How do NFTs Affect the Environment?

NFTs themselves have no environmental impact, but how they are produced can have significant environmental consequences. NFT is available on a digital marketplace: Typically, an NFT is listed in an NFT marketplace before it is minted. While listing an NFT does not require much energy, the location of the NFT listing will generally determine how much energy is required for the minting process. Choosing an NFT marketplace, such as OpenSea, that hosts the Ethereum platform, which employs Proof of Work, implies that the minting process will be energy-intensive, at least for the time being.

The purchase of an NFT is frequently the impetus for the NFT to be minted. The NFT is mined by cryptocurrency miners who control vast computing resources using Proof of Work. Mining is an energy intensive process, with specialized computing hardware consuming massive amounts of electricity. Miners compete to solve complex math problems as quickly as possible in order to earn the right to mint the NFT.

NFT is stored or transferred as follows: after you have completed the NFT purchase, you can store it or transfer it to another person. If the NFT is transferred to another NFT marketplace that uses Proof of Work, the same energy-intensive process that was used to mint the NFT is repeated. Simply storing an NFT consumes no energy.

Can NFTs Save Energy?

The process of minting or transferring an NFT is typically energy intensive, but it does not have to be. Blockchain platforms that use the Proof of Stake operating method can generate NFTs without using excessive amounts of electricity or negatively impacting the environment.

Make use of renewable energy: Miners who use Proof of Work to generate NFTs can use renewable energy sources. While Proof of Work mining requires a lot of energy, the source of that energy doesn’t have to be. Solar power is a popular option, but wind and hydroelectric power are also viable options.

Invest in renewable energy: Because some NFTs sell for high prices, a portion of the proceeds can be directed toward renewable energy investments. A large scale transition to renewable energy could reduce or eliminate the environmental impact of NFT production.

Invest in experimental technologies: The proceeds from NFT sales can also be used to fund research into experimental technologies that will help to mitigate or reverse the effects of climate change. Carbon capture and storage, which collects and pumps carbon dioxide emissions into the ground, is an example of an experimental technology that some believe has the potential to solve the climate change puzzle.

Purchase carbon offset credits: NFT investors who want to offset the environmental impact of their NFT purchase can do so by purchasing carbon offset credits. While purchasing carbon credits does not reduce carbon dioxide emissions, it does provide a financial incentive for others to reduce their total annual emissions.

Are NFTs good or bad for the Environemnt

Purchase Energy-Efficient NFTs

If you want to purchase a non-fungible token without harming the environment, you have these blockchain platforms supports the creation and exchange of NFTs and uses Proof of Stake:

Solana: The Solana blockchain is compatible with a wide range of NFT marketplaces, including Magic Eden, Solanart, and Rabbit Hole.

Algorand: In addition to several NFT marketplaces, the Algorand blockchain supports Aorist, a climate-focused NFT blockchain for artists. Because the Algorand blockchain is designed to never fork-split into duplicate versions, it is well suited to support NFTs.

Cardano: Cardano is a blockchain that is known for its environmental friendliness. CNFT and Galaxy of Art are two NFT marketplaces hosted on Cardano.

Tezos: The Tezos blockchain hosts several NFT marketplaces, including Rarible, which operates an NFT marketplace as well as supports artists’ creation of NFTs.


Fewer currencies may appear to have a lower carbon footprint, but this is often due to fewer transactions. However, there are digital assets that are more energy efficient, which means they have a lower environmental impact.

According to TRG Datacenters research, the following coins are the most energy efficient: IOTA (0.00011kWh), XRP (0.0079 kWh), and Chia (0.023kWh).

More than 45 companies and individuals from the crypto, finance, energy, and technology sectors have also signed on to the Crypto Climate Accord, which aims to decarbonize the industry and achieve net zero emissions from cryptocurrency-related electricity consumption by 2030.
