Can blockchain help combat climate change?

Blockchain’s transparency and traceability can aid sustainability and reduce carbon emissions for climate change.

With rising temperatures, melting ice caps and more frequent and intense extreme weather events, the effects of climate change are becoming more and more obvious. There is an urgent need to prevent climate change, and numerous technologies and methods are being investigated to do so. Blockchain technology is one of these possibilities, and it has the potential to be very effective in the fight against climate change.

At its core, blockchain is a decentralized ledger that can securely and transparently record transactions and store data. This technology has already been used in a variety of applications, from cryptocurrency to supply chain management. However, its potential applications in combating climate change are still being explored.

Here are a few ways in which blockchain can help combat climate change.

Creation and management of carbon credits

The creation and administration of carbon credits is one way that blockchain technology can help fight climate change. A tradable permit called a “carbon credit” permits the holder to emit a certain amount of greenhouse gases, such as carbon dioxide. To reduce their emissions, businesses and organizations can buy carbon credits, which can be traded on a market.

The management of carbon credits may become more transparent and effective with the use of blockchain. All carbon credit transactions can be tracked in real-time and documented using a decentralized ledger. By doing so, fraud can be avoided, and the intended use of carbon credits can be guaranteed.

Promote renewable energy sources

By establishing a decentralized energy infrastructure, blockchain technology can also encourage the adoption of renewable energy sources. Without the aid of a centralized organization or utility company, people and companies can buy and sell renewable energy directly from and to one another using a decentralized energy grid. This can support the adoption of renewable energy sources, such as solar and wind power, and lessen dependency on fossil fuels.

Supply chain management

Supply chain management is another area where blockchain technology is being used to tackle climate change. Businesses can find opportunities to lower their carbon footprint and make more sustainable decisions by utilizing blockchain to track the carbon footprint of products and materials across the supply chain. By promoting sustainable production and consumption practices, greenhouse gas emissions can be significantly reduced.

Monitoring and reporting carbon emissions

The monitoring and reporting of carbon emissions from numerous sources, such as businesses, vehicles and structures, can also be done using blockchain technology. Governments and organizations can more precisely measure and report on their emissions and monitor progress toward their emission reduction targets by utilizing a decentralized ledger to track emissions.

Challenges to implementing blockchain to reduce carbon emissions

Using blockchain technology to address climate change is not without its difficulties and restrictions. The requirement for standardization and compatibility is one obstacle. Blockchain needs a uniform set of rules and protocols that all stakeholders can agree upon in order to manage carbon credits and track emissions effectively.

The scalability of blockchain technology presents another difficulty. Many blockchain networks currently only have a modest amount of capacity and can only process a small number of transactions. If blockchain is widely utilized to manage carbon credits or track emissions, this might become a bottleneck.

Last but not least, there are issues with the energy usage of blockchain technology. Some of the environmental advantages of adopting blockchain to fight climate change may be outweighed by the energy consumption necessary for blockchain transactions.

The road ahead

Although blockchain technology is still in its infancy in terms of adoption and development, its prospective uses in halting climate change are promising. Blockchain can hasten the shift to a low-carbon economy by enhancing transparency, efficiency and accountability in regulating carbon emissions and encouraging sustainable practices.

Yet in order for blockchain to be successful in addressing climate change, there are also difficulties and constraints that must be overcome. Ultimately, a combination of technologies and solutions will be required to address the complex and urgent challenge of climate change.

Flare gets NFT platform to increase use cases for interoperability protocols

The NFT marketplace Sparkles launched on the layer-1 EVM Oracle platform Flare for interoperable protocols to expand use cases for NFTs and their holders.

Flare, the layer-1 Ethereum Virtual Machine (EVM) blockchain, went live on Jan. 10 after it launched two core protocols for decentralized interoperability applications. The blockchain network allows developers to create applications that are interoperable between various blockchain ecosystems and internet platforms.

Less than one month later, on March 2, Flare welcomed the nonfungible token (NFT) platform Sparkles on its layer-1 Oracle network.

According to the announcement a primary goal of the Sparkles NFT platform is to hone in on the interoperability of native Flare protocols to increase use cases for NFT utility.

The NFT platform has plans to target other major issues in the space, such as intellectual property (IP) rights, via attaching on-chain IP licensing to future collections. Sparkles also has plans of decentralizing its core technology and infrastructure after it transitions into a DAO.

Since its launch on Songbird, the canary network for Flare, in Jan. 2022, Sparkles has handled 90% of NFT sales, which accounts for $3.5 million in sales. It currently hosts over 3,200 collections.

Additionally, in 2021, Sparkles joined the Crypto Climate Accord with a pledge to become net-zero by 2023. The platform reports to have achieved an environmentally positive status via carbon credits, which it retired on-chain via the Toucan bridge. 

Interoperability will continue to be a big theme for the decentralized space going forward in 2023. It is one of the major focuses of many companies and communities in the space in the service of helping with scalability and onboarding more users. New tools like trustless bridges have been implemented in order to create safer options for the implementation of interoperable solutions. 

The Web3 Domain Alliance recently expanded with an addition of 51 new members, after which it named interoperability as one of its main focuses for the year.

Davos 2023: Education is key to driving sustainability in blockchain and beyond

Cointelegraph’s editor-in-chief Kristina Lucrezia Cornèr moderated a panel discussion at the 2023 Davos conference in Switzerland on sustainability in the blockchain world.

The World Economic Forum (WEF) in Davos, Switzerland, brings together global leaders and thinkers across various industries to hone in on global issues each year. As the world of crypto and blockchain continues to push into the mainstream, it has become a topic of discussion at the legacy event. 

Cointelegraph editor-in-chief Kristina Lucrezia Cornèr moderated a panel on Jan. 17, which touched on sustainability efforts in the blockchain industry. 

Even though not all panelists come from the same background, they unanimously highlighted education and learning as the key to driving sustainability in emerging technologies during “The emergence of Breakthrough Technologies” panel.

The panel’s focus viewed sustainability in the blockchain industry through two lenses. One is in the “green” sense of the word, with a more energy-efficient and sustainable future for the environment. The other speaks to the long-term impact of projects and initiatives in the greater Web3 space.

Mark Mueller-Eberstein, the CEO of business consultancy Adgetec Corporation, pointed out that the industry does suffer from “greenwashing,” but verification standards that can be taken from the blockchain can lead to productivity in sustainability practices in the industry.

“Knowing that we can trust the data is extremely important. This is why I think blockchain especially is so important.”

He continued to say that educating the community, especially the next generation, will be “the cornerstone for all of us, as societies and individuals.“

Christina Korp, the president of Purpose Entertainment and founder of SPACE for a Better World, highlighted the significance of education to older generations with an example of a United States congressman aged over 70 who began educating himself on artificial intelligence.

“How can all these people make the decisions about what happens with the laws when they don’t even understand the technology or this new world?”

The chief financial officer and treasurer of the Hedera Foundation, Betsabe Botaitis, also touched on trust as a foundation for a more sustainable industry, especially she said, as the blockchain industry can sometimes have a bit of a negative reputation.

“We need to be careful with that because it is easy to think that a new idea can be immediately funded. And that’s not always the case.”

Botaitis used carbon credit tracking as an example of a trust-building niche, in which blockchain can be utilized for this transparency and verification.

“It’s such an honor to see how companies are coming together to really build this trust infrastructure, an immutable layer.”

Botaitis continued by saying that creating and leaving a sustainable legacy for the next generation is not just about wealth, but ensuring a safe environment for that wealth and education is the key.

“There’s very, very little technology that is given for the education of wealth management. I think that it is the private sector that needs to have that education, the regulators and everyone that is having this conversation.”

Education continues to be a major touch point in the Web3 space, with many brands and initiatives focusing on educating users alongside technological developments. 

Carbon credit NFTs are only effective if burned, experts say

Environmental concerns plague both the crypto industry and the world at large. However, if used right, blockchain-based assets could offer some relief.

Using nonfungible tokens (NFTs) as carbon credits or carbon offsets reveals an outlet for Web3 technology to foster a more environmentally friendly future.

NFTs as carbon credits are a slow-rolling trend in the regenerative finance (ReFi) and decentralized finance (DeFi) markets. Most of this activity currently takes place on the Polygon blockchain, as it has already offset its entire carbon footprint. However, the way these digital assets work with carbon credits differs from other ventures in the space.

Rather than a store of wealth or a piece of unique digital art, carbon credit NFTs serve as a repository of information related to a specific batch of carbon offsets.

This information could include, but is not limited to, the total number of offsets (i.e., how many metric tonnes), the vintage year of the removal, the project name, the geographical location or the certification program utilized.

Such NFTs are then fractionalized into Ethereum-based ERC-20 tokens, fungible with each other.

However, unlike the majority of NFTs available to consumers, a properly functioning carbon credit NFT comes with a catch. In order for it to serve its true purpose — verifying and standing in for carbon emission offsets — it must be burned. In off-chain settings in the carbon market, this is called “retirement.”

A core member of KlimaDAO, a decentralized organization using DeFi to fight climate change, explained to Cointelegraph how this works both on- and off-chain:

“Retirement means that someone is essentially taking that carbon offset and claiming it for its environmental benefit, meaning that they’re basically offsetting their emissions. Then that carbon offset is permanently taken out of circulation and can no longer be traded or sold to anyone else.”

However, when it comes to retiring these carbon offsets in an on-chain setting, one must burn the token once the retirement certificate is obtained. In other words, it must be removed from the database and no longer available for trades.

“It’s very important that if there is any type of environmental claim being made regarding the offset being embedded in an NFT, that NFT is actually burned in some respect and a specific entity or individual is named to claim that environmental incident.

There are a large number of projects popping up in the space that claim to implement NFT technology for carbon offsets, including carbonABLE and MintCarbon.

However, with a market value of over $850 billion, the carbon credit industry is not a small one. Like other profitable markets, it is susceptible to scams. As NFTs continue to rise in popularity, NFT scams become more prevalent

KlimaDAO stressed that projects that claim NFTs as carbon credits should also carry accreditation from internationally recognized standards. Principally, an endorsement from the International Carbon Reduction and Offset Alliance.

If not, projects with this claim should be carefully considered before investing under that pretext. Although the carbon credit market is valuable, the way it operates is still unknown to the masses.

“The thing is, you’re combining Web3 with a market that isn’t very well known. So, unfortunately, you do have various actors that are taking advantage of people.”

Nonetheless, these carbon offset NFTs could be really useful if fully disclosed because they would be doing what they promise. These offsets provide an injection of capital from some other source to maintain and develop a project. This could range from renewable energy generation to forest protection or reforestation.

Bitcoin mining to harness onsite natural gas emissions: Ark Invest

A new report reveals an angle for sustainability in Bitcoin mining through harnessing onsite natural gas emissions.

Data from a recent Ark Invest report highlights another utility for Bitcoin (BTC) mining in the realm of sustainability and energy. 

According to the findings, there is enormous potential to transform methane emissions into energy for Bitcoin mining, which, in turn, will turbocharge solar and wind-generated electricity at onsite wells.

Annual gas flaring emissions equal 140 billion cubic meters, along with an additional 125 billion cubic meters in annual methane emissions. Therefore, left untouched, this means 265 billion cubic meters of natural gas emissions are wasted yearly. However, an analysis of the methane needed for the current Bitcoin hashrate stands at only 25 billion.

While harnessing the entirety of the emissions is impossible due to the oil industry’s preexisting flaring operations investments, capturing methane is a viable and early solution. Ark Invest’s Sam Korus tweeted that over half of all vented methane occurs onsite at wells. This makes the location a prime spot for mining to capture such emissions and productively employ them.

Additionally, instead of the methane being vented, it would be able to generate electricity at rates far below what mining companies currently pay.

Recently, the mining industry has been showing signs of increased energy efficiency and a pivot towards sustainability.

Last week, the Bitcoin Mining Council released its Q2 review of the network. It revealed the industry’s use of sustainable energy is up 6% from the same quarter in the previous years. In the conclusion to their findings, the council referred to Bitcoin mining as “one of the most sustainable industries globally.”

However, this has been an active effort to change on the part of the mining industry. Previously, environmentalists shamed the industry due to its unjustifiable carbon footprint.

Korus suggests that while there are other ways to harness methane, Bitcoin mining is an ideal option as “It is highly scalable with modular hardware that can be transported to and shifted among operating well sites.”

While the new data backs up these claims, they are not new. There are already companies actively doing so. Back in February, Cointelegraph spoke with Kristian Csepcsa, the chief marketing officer of Slush Pool, on how miners are aiding oil companies with flare reduction by running their generators on natural gas, which would otherwise be burned off.

Nonetheless, there are still skeptics. One Twitter user pointed out that the emissions in question are not naturally occurring. Rather, they are extracted via fossil fuel extraction, which due to climate change, is under pressure to be cut entirely.

As the industry continues to adapt to global sustainability standards, time will tell if such solutions will bring about the future of Bitcoin mining and energy production.

MiCA and ToFR: The EU moves to regulate the crypto-asset market

The EU crypto regulation: With the main topics approved, who is affected and what are the possible impacts on the crypto industry?

On the last day of June, the European Union reached an agreement on how to regulate the crypto-asset industry, giving the green light to Markets in Crypto-Assets (MiCA), the EU’s main legislative proposal to oversee the industry in its 27 member countries. A day earlier, on June 29, lawmakers in the member states of the European Parliament had already passed the Transfer of Funds Regulation (ToFR), which imposes compliance standards on crypto assets to crack down on money laundering risks in the sector. 

Given this scenario, today we will further explore these two legislations that, due to their broad scope, can serve as a parameter for the other Financial Action Task Force (FATF) members outside of the 27 countries of the EU. As it’s always good to understand not only the results but also the events that led us to the current moment, let’s go back a few years.

The relation between the FATF and the newly enacted EU legislation

The Financial Action Task Force is a global intergovernmental organization. Its members include most major nation-states and the EU. The FATF is not a democratically elected body; it is made up of country-appointed representatives. These representatives work to develop recommendations (guidelines) on how countries should formulate Anti-Money Laundering and other financial watchdog policies. Although these so-called recommendations are non-binding, if a member country refuses to implement them, there can be serious diplomatic and financial consequences.

Along these lines, the FATF released its first guidelines on crypto assets in a document published in 2015, the same year when countries like Brazil started debating the first bills on cryptocurrencies. This first document from 2015, which mirrored the existing policies of the United States regulator the Financial Crimes Enforcement Network, was reassessed in 2019, and on October 28, 2021, a new document titled “Updated Guidance for a risk-based approach to virtual assets and VASPs” came out containing the current FATF guidelines on virtual assets.

This is one of the reasons why the EU, the U.S. and other FATF members are working hard to regulate the crypto market, in addition to the already known reasons such as consumer protection, etc.

If we look, for example, at the 29 of 98 jurisdictions whose parliaments have already legislated on the “travel rule,” all have followed the FATF’s recommendations to ensure that service providers involving crypto assets verify and report who their customers are to the monetary authorities.

The European digital financial package

MiCA is one of the legislative proposals developed within the framework of the digital finance package launched by the European Commission in 2020. This digital finance package has as its main objective to facilitate the competitiveness and innovation of the financial sector in the European Union, to establish Europe as a global standard setter and to provide consumer protection for digital finance and modern payments.

In this context, two legislative proposals — the DLT Pilot Regime and the Markets in Crypto- Assets proposal — were the first tangible actions undertaken within the framework of the European digital finance package. In September 2020, the proposals were adopted by the European Commission, as was the Transfer of Funds Regulation.

Related: European ‘MiCA’ regulation on digital assets

Such legislative initiatives were created in line with the Capital Markets Union, a 2014 initiative that aims to establish a single capital market across the EU in an effort to reduce barriers to macroeconomic benefits. It should be noted that each proposal is only a draft bill that, to come into force, needs to be considered by the 27 member countries of the European Parliament and the Council of the EU.

For this reason, on June 29 and June 30, two “interim” agreements on ToFR and MiCA, respectively, were signed by the political negotiation teams of the European Parliament and the Council of the European Union. Such agreements are still provisional, as they need to pass through the EU’s Economic and Monetary Affairs Committee, followed by a plenary vote, before they can enter into force.

So, let’s take a look at the main provisions agreed to by the political negotiation teams of the European Parliament and the European Council for the crypto market (cryptocurrencies and asset-backed tokens such as stablecoins).

Main “approved” topics of the Transfer of Funds Regulation

On June 29, the political negotiation teams of the European Parliament and the Council of the European Union agreed on provisions of the ToFR on the European continent, also known as the “travel rules.” Such rules detailed specific requirements for crypto asset transfers to be observed between providers such as exchanges, unhosted wallets (such as Ledger and Trezor) and self-hosted wallets (such as MetaMask), filling a major gap in the existing European legislative framework on money laundering.

Related: Authorities are looking to close the gap on unhosted wallets

Among what has been approved, following the FATF recommendation line, the main topics are as follows: 1) All crypto asset transfers will have to be linked to a real identity, regardless of value (zero-threshold traceability); 2) service providers involving crypto assets — which the European legislation call Virtual Asset Service Providers, or VASPs — will have to collect information about the issuer and the beneficiary of the transfers they execute; 3) all companies providing crypto-related services in any EU member state will become obliged entities under the existing AML directive; 4) unhosted wallets (i.e., wallets not held in custody by a third party) will be impacted by the rules because VASPs will be required to collect and store information about their customers’ transfers; 5) enhanced compliance measures will also apply when EU crypto asset service providers interact with non-EU entities; 6) regarding data protection, travel rules data will be subject to the robust requirements of the European data protection law, General Data Protection Regulation (GDPR); 7) the European Data Protection Board (EDPB) will be in charge of defining the technical specifications of how GDPR requirements should be applied to the transmission of travel rules data for cryptographic transfers; 8) intermediary VASPs that perform a transfer on behalf of another VASP will be included in the scope and will be required to collect and transmit the information about the initial originator and the beneficiary along the chain.

Here, it is important to note that European ToFR seems to have fully followed the recommendation enshrined in FATF Recommendation 16. That is, it is not enough for Virtual Asset Service Providers to share customer data with each other. Due diligence must be performed on the other VASPs with which their customers transact, such as checking whether other VASPs perform Know Your Customer checks and have an Anti-Money Laundering/Combating the Financing of Terrorism (AML/CFT) policy, or facilitate transactions with high-risk counterparties.

In addition, this agreement on the ToFR must be approved in parallel by the European Parliament and Council prior to publication in the Official Journal of the EU, and will commence no later than 18 months after it enters into force — without having to wait for the ongoing reform of the AML and counter terrorism directives.

Main “approved” points of the Markets in Crypto-Assets

MiCA is the key legislative proposal regulating the crypto sector in Europe, although it is not the only one within the European digital finance package. It is the first regulatory framework for the crypto-active industry on a global scale, as its approval imposes rules to be followed by all 27 member countries of the bloc.

As already mentioned, negotiators from the EU Council, the Commission and the European Parliament, under the French presidency, reached an agreement on the supervision of the Markets in Crypto-Assets (MiCA) proposal during the June 30 political trialogue.

The key points approved in this agreement are as follows:

  • Both the European Securities and Market Authority (ESMA) and the European Bank Authority (EBA) will have intervention powers to prohibit or restrict the provision of Virtual Asset Service Providers, as well as the marketing, distribution or sale of crypto assets, in case of a threat to investor protection, market integrity or financial stability.
  • ESMA will also have a significant coordination role to ensure a consistent approach to the supervision of the largest VASPs with a customer base above 15 million.
  • ESMA will be tasked with developing a methodology and sustainability indicators to measure the impact of crypto assets on the climate, as well as classifying the consensus mechanisms used to issue crypto assets, analyzing their energy use and incentive structures. Here, it is important to note that recently, the European Parliament’s Committee on Economic and Monetary Affairs decided to exclude from the MiCA (by 32 votes to 24) proposed legal provision that sought to prohibit, in the 27 EU member countries, the use of cryptocurrencies powered by the “proof-of-work” algorithm.
  • Registration of entities based in third countries, operating in the EU without authorization, will be established by ESMA based on information submitted by competent authorities, third country supervisors or identified by ESMA. Competent authorities will have far-reaching powers against listed entities.
  • Virtual Asset Service Providers will be subject to robust Anti-Money Laundering safeguards.
  • EU VASPs will have to be established and have substantive management in the EU, including a resident director and registered office in the member state where they apply for authorization. There will be robust checks on management, persons with qualifying holdings in the VASP or persons with close ties. Authorization should be refused if AML safeguards are not met.
  • Exchanges will have liability for damages or losses caused to their customers due to hacks or operational failures that they should have avoided. As for cryptocurrencies such as Bitcoin, the brokerage will have to provide a white paper and be liable for any misleading information provided. Here, it is important to know the difference between the types of crypto assets. Both cryptocurrencies and tokens are types of crypto assets, and both are used as a way to store and transact value. The main difference between them is logical: cryptocurrencies represent “embedded” or “native” transfers of value; tokens represent “customizable” or “programmable” transfers of value. A cryptocurrency is a “native” digital asset on a given blockchain that represents a monetary value. You cannot program a cryptocurrency; that is, you cannot change the characteristics of a cryptocurrency, which are determined in its native blockchain. Tokens, on the other hand, are a customizable/programmable digital asset that runs on a second or third generation blockchain that supports more advanced smart contracts such as Ethereum, Tezos, Rostock (RSK) and Solana, among others.
  • VASPs will have to segregate clients’ assets and isolate them. This means that crypto assets will not be affected in the event of a brokerage firm’s insolvency.
  • VASPs will have to give clear warnings to investors about the risk of volatility and losses, in whole or in part, associated with crypto-actives, as well as comply with insider trading disclosure rules. Insider trading and market manipulation are strictly prohibited.
  • Stablecoins have become subject to an even more restrictive set of rules: 1) Issuers of stablecoins will be required to maintain reserves to cover all claims and provide a permanent right of redemption for holders; 2) the reserves will be fully protected in the event of insolvency, which would have made a difference in cases like Terra.

First introduced in 2020, the MiCA proposal went through several iterations before reaching this point, with some proposed legislative provisions proving more controversial than others, such as NFTs remaining outside the scope but being able to be reclassified by supervisors on a case-by-case basis. That is, nonfungible tokens have been left out of the new rules — although, in the MiCA settlement discussions, it was pointed out that NFTs may be brought into the scope of the MiCA proposal at a later date.

In the same vein, DeFi and crypto lending were left out in this MiCA agreement, but a report with possible new legislative proposals will have to be submitted within 18 months of its entry into force.

As for stablecoins, a ban on them was considered. But, in the end, the understanding remained that banning or fully limiting the use of stablecoins within the EU would not be consistent with the goals set at the EU level to promote innovation in the financial sector.

Final considerations

Shortly after the ToFR and MiCA agreements were reported, some criticized the ToFR, pointing out, for example, that while legislators had done their part, the approved origin and recipient identification measures will only reach central bank digital currencies, but not privacy-focused blockchain networks like Monero and Dash.

Others have argued for the need for a harmonized and comprehensive framework like the MiCA proposal, which brings regulatory clarity and boundaries for industry players to be able to operate their businesses safely across the various EU member countries.

Do you think European policymakers have been able to use this opportunity to build a solid regulatory framework for digital assets that promotes responsible innovation and keeps bad actors at bay? Or do you think that new means of transactions will emerge to impede the traceability of crypto assets with zero threshold? Do you see a need for regulation to prevent the loss of more than $1 trillion in value of the digital asset industry in recent weeks caused by the announced risk of algorithmic stablecoins? Or do you believe that market self-regulation is sufficient?

It is true that market adjustment is shaking up many scammers and fraudsters. But unfortunately, it is also hurting millions of small investors and their families. Regardless of positioning, as an industry, the crypto sector needs to be mindful of accountability to users, who can range from sophisticated investors and technologists to those who know little about complex financial instruments.

Bitcoin’s real energy use questioned as Ethereum founder criticizes BTC

A founding member of Ethereum has claimed that Bitcoin uses nearly 1% of the world’s electricity, but different sources put it substantially lower.

The ever-raging debate around Bitcoin’s energy consumption has been re-ignited, with founding member of Ethereum Anthony Donofrio claiming that Bitcoin is using “way too much” energy. 

According to figures from Digiconomist, Bitcoin (BTC) currently uses 0.82% of the world’s power while Ethereum (ETH) uses 0.34%. Ethereum researcher Justin Drake posted the figures to his 56,000 followers that Donofrio retweeted, stating:

Ethereum proponents are attempting to take shots at Bitcoin while simultaneously promoting Ethereum’s upcoming transition to proof-of-stake. Drake added another tweet moments later that read: “Ethereum post-merge: 0.000% of world.”

However, the validity of the figures are in doubt.

Even Drake was forced to acknowledge alternative sources of data in a later tweet, which estimated energy consumption figures at nearly 60% lower.

Data sourced from Digiconomist, which markets itself as a platform that “exposes the unintended consequences of digital trends,” has drawn criticism from blockchain industry professionals in the past. The most notable of these is fellow Ethereum developer Josh Stark, who called out the publication for frequently presenting the worst-case scenario when it comes to blockchain technology.

In November last year, Stark published a Twitter thread that questioned the accuracy of Digiconimist’s research methodology. Stark pointed out that almost all of the figures concerning blockchain power consumption were at the “very high end” of any theoretical outcome, especially when compared to more rigorous sources like the University of Cambridge.

Where Digiconomist claims that Bitcoin currently consumes 204 terawatt hours (TWh) worth of electricity per year, the University of Cambridge’s Bitcoin Electricity Consumption Index estimates that Bitcoin’s real consumption is much closer to 125 TWh, a 39% difference.

While it may be a well-known fact that Bitcoin’s proof-of-work consensus mechanism is an energy-consuming process, the discussion around just how much power the Bitcoin network actually uses remains a hot-button issue.

According to a report from Cointelegraph, putting a specific number on Bitcoin’s actual power consumption can be quite difficult because of the variation in energy sources that power Bitcoin mining globally.

As of January this year, nearly 60% of global mining operations were reportedly powered by renewable energy sources, and Bitcoin mining operators are rushing to utilize “stranded” natural gas resources that would normally be burned off. Additionally, a report published by CoinShares in January this year found that Bitcoin mining may account for just 0.08% of the world’s total CO2 emissions in 2021.

Sam Tabar, chief security officer of Bit Digital, a publicly-traded Bitcoin mining company, told Cointelegraph that the environmental impact of Bitcoin is frequently exaggerated by critics:

“The environmental impact of Bitcoin mining is massively exaggerated by critics & traditional financial authorities (IMF, etc.) because they know they can divide a new counterculture movement by using fake environmental arguments. They are trying to gaslight us against each other. They gaslight the world with fake green arguments, and I understand why: They don’t want to lose influence over the levers of power of a system that only works for the elite.”
