- The technology underlying NFTs has enormous application potential, yet some concerns have been raised concerning its environmental impact. Some NFTs use power-intensive Proof-of-Work (PoW) mechanisms, although more NFTs use more environmentally friendly Proof-of-Stake (PoS) models.
- The carbon footprint of NFTs has not been statistically established. Blockchain transactions using NFTs are low in scale and cannot be compared in terms of carbon emissions to transportation, logistics, and industries involved in the production of physical artwork.
- Every technological advancement has an environmental impact, but the underlying technologies evolve and become more efficient and environmentally friendly over time.
The rapid rise of the NFT sector has resulted in an increase in discussions about the environmental impact of such blockchain-based activities. The most serious problems include claims that NFTs cause substantial carbon emissions since they are manufactured using power-intensive Proof-of-Work (PoW) blockchains such as Bitcoin and Ethereum.
However, NFTs are more than just their environmental impact; not all NFTs are fueled by PoW models, and many have enormous potential in influencing the modern world. As a result, when contemplating the true benefits that NFTs can have for society and the global economy, it is vital to find a balance between scientific developments and environmental sustainability.
Why Do NFTs Produce Carbon?
Non-fungible tokens are primarily issued on PoW networks, the most popular of which is Ethereum. These networks rely on coin mining, which necessitates massive amounts of energy to perform complex computations utilizing modern computers and specialized mining devices. The equipment consumes a lot of energy and generates a lot of heat, which results in carbon emissions.
Anything housed on blockchain technology generates carbon in the strictest sense. However, because of the media attention that many NFTs have gotten, they have been prominently connected with energy-intensive and carbon-emitting activities.
Is there a direct, causal relationship between NFTs and carbon emissions?
The first problem is that NFTs rely on current blockchains such as Bitcoin and Ethereum, which use PoW consensus methods and consume massive amounts of energy. The electricity is utilized to power and cool the mining equipment. The majority of mining operations remain in China, which relies heavily on coal and other fossil fuels for energy generation.
Another factor is the excitement around NFTs, which has drawn more individuals to the Ethereum network. These new market players purchase more ETH, which increases network utilization and increases CO2 emissions. The more the utilization of a blockchain, the more energy it takes.
The claims are fair from a technological aspect, however calculating the exact quantity of CO2 emissions caused by NFT transactions is unfeasible. The reason for this is a lack of statistical data, as well as the fact that NFTs account for only a small part of all blockchain use cases.
The Environmental Impact of NFTs vs. Traditional Art
If CO2 emissions are used as a proxy for assessing the environmental impact of NFTs, then physical forms of art have been around much longer and have a greater environmental impact.
Physical forms of art necessitate the use of energy-intensive production methods such as chemical industries, resource extraction, precious metal and wood processing, transportation, and a variety of other activities. The figures involved in the environmental impact of traditional art are also considerably more difficult to determine because there is no specific data relating to artwork other than preliminary statistics.
Even if we simply analyze one industry involved in the creation and dissemination of traditional art, the carbon footprint from this activity is significant. Consider global logistics as a type of traditional art in this case. NFTs, unlike actual artworks, do not need to be carried because they are digital and can be supplied quickly for a fraction of the carbon footprint of an aircraft or cargo truck hauling a painting or statue. The distribution of resources required to create art is also a factor, as logistics and transportation are the world’s largest carbon emitters.
The ultimate purpose of evaluating environmental impact is to reduce carbon footprints. Statistically, NFT artworks may have lower emissions than their physical equivalents in some circumstances, even when employing PoW blockchains.
The Role of Proof-of-Stake in Reducing NFT-Related Emissions
Contrary to popular belief, many NFTs are built on blockchains using Proof-of-Stake (PoS) models, which use less energy because each miner does not have to maintain their own mining equipment. Instead, PoS requires only a small number of capable nodes to manage the network by confirming transactions after receiving a sufficient amount of stakes from coin holders as a trust deposit.
The PoS strategy is typically seen as more environmentally benign than the PoW model since it avoids the use of massive mining operations. Furthermore, with DeFi, PoS networks can generate passive money. As a result, many NFT marketplaces and authors are switching to PoS networks. With the Ethereum 2.0 update, Ethereum is also on its road to a PoS paradigm.
The Binance NFT Marketplace is an example of a blockchain platform that decreases the environmental impact of NFTs by using the Proof of Staked Authority (PoSA) network, which is environmentally friendly, energy-efficient, and sustainable. The fact that the Binance NFT Marketplace is available to all users without the requirement for multiple accounts makes it even less blockchain-intensive.
NFTs Are More Than Just Their Environmental Impact
NFTs have greater value than the original hoopla connected with their increase in popularity due to their numerous use cases as proof of ownership and real-world asset digitization instruments. NFTs are some of the most relevant crypto assets with utility value that will enable the transition to Web 3.0 – the decentralized, intelligent evolution of the Internet.
Some NFTs also promote charitable causes by allowing inventors and artists to be fairly compensated for their work and ensuring everyone’s compliance with intellectual property laws. The potential of NFTs is only now being realized, and numerous platforms are banding together to promote the benefits the technology can provide.
Binance has also launched many premium drops in esports, sports, gaming, and arts to further empower the community in order to promote the immense potential of NFTs. The NFT for Good event, organized by Binance NFT Marketplace and Binance Charity, is one example of how NFTs enable artists to channel their talent into social good actions that benefit society.
CO2 is emitted by blockchain-based transactions that support NFTs. Many producers and NFT markets are seeking for alternatives and constantly developing the sector in order to avoid this damage. Major blockchain networks are also contributing to the cause by shifting to more energy-efficient technologies such as PoS.
NFTs have a huge potential for real-world applications. It is also obvious that any technological advance, whether internal combustion engines, AI, machine learning, or smartphones, will have an environmental impact. Everything requires manufacturing capacity and energy to function. However, as time passes, existing technologies improve, just as electric vehicles phase out internal combustion engines. Because innovations are necessary for advancement, it is critical to strike a balance, and blockchain technologies, particularly NFTs, are already making headway in this regard.
