Cut the Pollution and the Excuses

On September 15, 2022, Ethereum, the second largest cryptocurrency, slashed its electricity use by 99.95%, proving that a code change is technically and politically possible. Ethereum's Merge leaves Bitcoin as the largest cryptocurrency climate polluter. It doesn't have to be this way.

It can be done and has been done. Ethereum changed its code–reducing its electricity use by 99.95%. Ethereum moved from using the highly energy-intensive Proof of Work (PoW) consensus mechanism to Proof of Stake (PoS), a much more energy-efficient cryptocurrency validation protocol. This move leaves Bitcoin in the dust as one of the largest cryptocurrencies using an outdated protocol contrary to the growing clean energy economy.

With climate change-driven wildfires and floods raging worldwide and destroying lives and livelihoods, many countries and entire sectors of the economy are racing to decarbonize and minimize energy use. Ethereum has cut its energy use by 99%, joining other protocols that also use tiny amounts of energy. Then there’s Bitcoin, whose most prominent and loudest boosters proclaim it will never change. Bitcoin mining wastes energy by design. It requires millions of specialized computers to perform trillions of computations to solve complex mathematical puzzles to validate transactions. These computers use insatiable amounts of electricity resulting in excessive air and water pollution, electronic waste, noise pollution from the whirring computers working 24-7, and increased electricity rates for utility ratepayers.

Ethereum’s move to a dramatically more energy-efficient consensus mechanism shows that a code change is technically and politically feasible.

A little more than a decade ago, Bitcoin changed the global financial system. But without a serious strategy to address its egregious energy consumption in a rapidly warming world, Bitcoin risks getting left behind. We call on Fidelity, PayPal, Block, BlackRock, and other financial institutions and asset managers to support climate-friendly cryptocurrency protocols that are at least as efficient as Proof of Stake. Support the call for a code change for the people and the planet before it’s too late. It’s time for Bitcoin to cut the excuses and the pollution.

Financial Institutions Need to Support a Bitcoin Code Change

Many financial institutions, including central banks, money managers, investment firms, and insurance companies, have made climate commitments to reach net zero by 2050 or have Environmental, Social, and Government (ESG) criteria for either their internal operations or their investments. Yet, many continue to invest in fossil fuel projects or companies. According to Reclaim Finance, an analysis of the policies adopted by banks, insurers, and investors showed that no major financial player has adopted measures to end fossil fuel development. More so, many companies like BlackRock, Fidelity, Vanguard, CitiGroup, JPMorgan Chase, Goldman Sachs, Visa, Mastercard. and others offer various Bitcoin products, invest in Bitcoin mining, and provide Bitcoin transactional services, despite its climate-polluting consensus mechanism.

More worrisome is that these same firms know about this problem. In 2017, Mastercard stated in its Corporate Sustainability Report that "new research shows that cryptocurrencies like Bitcoin are inherently more energy intensive than Mastercard's payment network." Yet, Mastercard is rushing to increase its Bitcoin transactional services despite its 2040 "net zero" climate pledge. Fidelity states on its website that "robust sustainability practices can be critical to an investment's long-term success." Yet, Fidelity has also invested in Bitcoin mining, offers Bitcoin products to millions of their 401(k) customers, and has plans to debut a retail crypto trading platform. Goldman Sachs has begun trading bitcoin futures with Galaxy Digital.

BlackRock is deepening its climate problem with its latest Bitcoin loan to Core Scientific, a Bitcoin mining company that uses coal power in Kentucky.  This latest loan follows $37.9 million of secured convertible notes to the same company,  a 6.71% stake in Marathon Digital Holdings (MARA), and 6.61% of Riot Blockchain (RIOT). BlackRock also offers Bitcoin investments to institutional investors.

BlackRock, Fidelity, Vanguard, CitiGroup, JPMorgan Chase, Goldman Sachs, Visa, Mastercard, and American Express are ramping up their Bitcoin business while dealing with a growing climate risk on their balance sheets. With increased scrutiny from proposed legislation from policymakers coupled with climate action demands from their customers, these investments present reputational and financial risk. It doesn't have to be this way due to the options of accessible, clean, and more efficient cryptocurrency consensus mechanisms that use 99% less energy.

Institutional investors like Fidelity, BlackRock, Goldman Sachs, and Vanguard, banks like CitiGroup and JPMorgan Chase, and payment processors like Visa and Mastercard can align their climate, and ESG commitments by leveraging their influence to push for a code change that would make Bitcoin validations reduce energy use and emissions. The financial institutions profiting from Bitcoin can bring their clout and resources to the growing movement calling for a Bitcoin code change and investment in what matters most: a thriving, livable planet.

BlackRock and bank JP Morgan Chase lead the pack with Bitcoin investments and products. Despite sustainability commitments to reduce carbon emissions, neither company has taken action to address Bitcoin's environmental impact.

Learn more about how BlackRock, Fidelity, Vanguard, CitiGroup, JPMorgan Chase, Goldman Sachs, Visa, Mastercard, and American Express investments in Bitcoin mining, offering of Bitcoin products, and services are fostering climate pollution.

Government Policy can Rein In Bitcoin’s Energy and Climate Impacts

Bitcoin and other Proof of Work cryptocurrencies pose risks to our climate, local air, water quality, grid stability, and electricity rates, necessitating government regulation to curb these impacts and demand disclosure of these risks to the public.

With increasing numbers of cryptocurrency investors and consumers, national, state, and utility regulators can implement a range of rules, laws, and incentives to clean up Bitcoin's climate and local impacts to determine the best approach for each jurisdiction. The key question for policymakers and regulators is how to maximize cryptocurrency's potential benefits while significantly reducing its environmental and social impacts.

Some countries like China and Kosovo have banned Bitcoin mining due to its excessive electricity use. As a result, Bitcoin mining companies in the U.S. and Kazakhstan have had explosive growth due to abundant and cheap energy sources that mainly depend on coal and other fossil fuels. From August 2019 to January 2022, the United States' share of global mining increased from four percent to nearly 38 percent. And new research from the Cambridge Centre for Alternative Finance shows that Chinese bitcoin mining activity has returned illegally, showing that banning miners is a short-term intervention. 

With this rapid increase, national and state regulatory agencies grapple with understanding the scale of the issue and their regulatory jurisdiction and gaps. For example, there is no national or state reporting requirement or compilation of the Bitcoin mining locations and no federal regulations governing cryptomining impacts such as pollution or excessive energy consumption. 

Policymakers and the public need more comprehensive and verified information about where operations are located, how much energy they consume, and the energy sources. There needs to be more data about the associated air and noise pollution, water contaminants, e-waste, and GHG emissions. Fortunately, the European Union (E.U.) and the United States government are starting to take action. In July 2022, with the Markets in Crypto-Assets (MiCA) law, the European Parliament and E.U. states agreed to regulate cryptocurrencies, including a requirement that companies selling tokens on the continent disclose their environmental impact. The law will also require cryptocurrency companies to reveal precisely how much energy cryptoassets consume and the amount of GHG emissions created from the validation processes. This move was the first significant regulation to provide transparency to crypto mining's climate impact.

In August 2022, Sens. Debbie Stabenow (D-Mich.), John Boozman (R-Ark.), Cory Booker (D-N.J.), and John Thune (R-S.D.) also introduced legislation that included a disclosure provision to increase transparency about how much and what type of power is used by energy-intensive digital assets like bitcoin.

In November 2022, Senator Ed Markey (D-Mass.) and U.S. Representative Jared Huffman (D-Calif.) introduced The Crypto-Asset Environmental Transparency Act that would:

--require cryptocurrency mining operations consuming more than five megawatts of power to report GHG emissions under the Clean Air Act.

--require the Environmental Protection Agency to lead a detailed interagency study of the environmental impacts of crypto-asset mining in the U.S.

--amend the Energy Independence and Security Act of 2007 to include cryptocurrency mining facilities in the definition of data center buildings.

U.S. states can also curtail Bitcoin mining impacts. In November 2022, N.Y. state placed a two-year pause on cryptocurrency mining, becoming the first state to do so. The law enacts a moratorium on new and renewed air permits to operate fossil fuel power plants that provide electricity for cryptocurrency mining. It also requires New York's Department of Environmental Conservation to study the environmental impacts of cryptocurrency mining.

State and local utility regulators can provide ratepayer protection from cryptocurrency mining companies, including those that oversee municipal utilities and rural electric cooperative board members, public utility commissions, energy regulators, and regional energy system market monitors. The Earthjustice and Sierra Club report, THE ENERGY BOMB

How Proof-of-Work Cryptocurrency Mining Worsens the Climate Crisis and Harms Communities Now outlines several actions that regulators, electric utilities, and grid operators can take:

--Refrain from approving power purchase agreements with cryptocurrency mining operations unless those utilities demonstrate the deal will not adversely impact other ratepayers, including by raising rates or increasing costs. State regulators and lawmakers should work with municipal and cooperative utilities to do the same.

--Ensure that cryptocurrency miners are not given discounted rates and instead allocate costs and adopt rates that protect existing consumers from higher wholesale prices, cost shifting, and stranded assets.

--Assess utility plans to increase or maintain obsolete capacity (such as old fossil generators) in response to cryptocurrency mining operations, and ensure that existing ratepayers are held harmless. 

--Consider Systems Benefit Charges (SBCs) or on-bill surcharges to cryptocurrency mining operations to fund mitigation measures and protect ratepayers against stranded asset costs.

--Review the impact of cryptocurrency mining operations on regional resource adequacy and the cost to serve customers.

--Establish and require best management practices for high-density load energy users, such as energy efficiency requirements and power density limits.

--Utilities should develop rate structures for cryptocurrency miners that ensure those operations pay their fair share of infrastructure upgrades at the time of interconnection.

--Independent system operators can develop guidance for the interconnection of high-density electricity users, including emergency response rules that prioritize the integrity of grid operations and treat cryptocurrency mining as a highly interruptible, "flexible" load.

The Real Value of NFTs Starts with a Climate-friendly Blockchain

While many factors can determine the value of an NFT (non-fungible tokens), one must stand out above all others–whether an NFT is based on a climate-friendly blockchain. NFT creators can now consciously decide to create a token on a blockchain that doesn’t rely on a climate-polluting code like that used by Bitcoin. That’s the right decision with an immeasurable value.

For many NFT creators, this decision was made for them when Ethereum’s code changed to a Proof of Stake consensus mechanism in September 2022. In switching to Proof of Stake, Ethereum’s energy requirements decreased by 99.95% compared to when it used a Proof of Work (PoW) consensus mechanism. This code change meant that NFTs on the Ethereum blockchain were now climate-friendly and not dependent on a PoW blockchain that uses massive amounts of electricity to validate transactions. For example, in one year, PoW Bitcoin uses as much electricity as the Netherlands and emits over 63 metric tons of GHG emissions, more than Hungary emits annually. “In stark contrast to Bitcoin, NFTs on Ethereum and almost any other platform now have the intrinsic value of being based on an energy-efficient consensus mechanism. This helps in the fight against climate change but also results in less air, water, and noise pollution, ” said Mike Brune, director of the “Change the Code, Not the Climate” campaign.

NFT creators, including artists, who didn’t want to use a PoW platform for their NFT art due to contributing to massive climate pollution have a clear choice with far less environmental impact. However, with the launch of an  NFT protocol, recently acquired by a PoW mining company, now on the Bitcoin mainnet, some creators might be considering a Bitcoin blockchain platform. NFTs on the Bitcoin platform would only exacerbate climate pollution by causing more transactions using more electricity from dirty fossil fuel power plants.

We strongly encourage creators to choose a PoS protocol blockchain or similar that is equally as energy efficient and not use a Bitcoin or other Proof of Work blockchain for NFTs. Rather than using a consensus mechanism that primarily relies on coal power, choose the one that doesn’t contribute to climate change and creates real tangible value for our planet. 

“The art community is already experiencing the benefits of utilizing eco-friendly blockchain solutions, like Proof of Stake, for the creation of NFTs. By adopting these sustainable platforms, we not only amplify the value of our artwork but also contribute to fostering a greener and more sustainable future for the NFT industry. It is imperative to distance ourselves from outdated Proof of Work solutions, such as Bitcoin, and instead, embrace the boundless opportunities that NFTs offer to artists. Let us collectively endeavor to achieve a sustainable and innovative NFT space that aligns with our core values of creativity, ingenuity, and accountability,” said Mo Ghoneim, founder of Arts Help and founding member of Conscious Crypto Creator movement. NFT artists can use their art and voice to call for a Bitcoin code change and become a Conscious Crypto Creator.

Communities Impacted By Bitcoin Pollution

Bitcoin's backyard blight and its toll on communities

Imagine a digital asset that requires so much energy it brings dirty coal-fired power plants back online, harming communities with air, water, and noise pollution 24/7. In the U.S., that's often the cost of validating Bitcoin transactions on a blockchain using thousands of computers called mining rigs. Sadly, local communities living near Bitcoin mining rigs shoulder those costs. An upcoming exclusive Environmental Working Group (EWG) series, Proof of Problems, profiles how the Bitcoin "Proof of Work" computer code for validating transactions creates air, climate, water, waste, and noise pollution for those living nearby. The report spotlights the experiences of communities across six states and how the arrival of Bitcoin mining has changed their lives and environments for the worse.

While the impacts of these Bitcoin mining operations might vary from community to community, it's clear that these associated environmental and health harms are entirely preventable. What needs to happen from the enterprising Bitcoin community is realizing the harmful impact of proof of work throughout the United States and a commitment to developing a much more efficient validation process like a Proof of Stake code or similar that is 99.95% more energy efficient. A code change is possible; it takes the will and consensus of the community to come together and care enough to make innovative changes that will stop harming people and the climate. One sector can make a big difference in pushing for a code change: finance. 

The financial sector bolsters Bitcoin – from funding large mining companies, facilitating conversions to and from fiat currencies, and making the technology more accessible and widely adopted. Companies like Fidelity Investments boost Bitcoin despite pledges and efforts to reduce climate emissions and increase corporate sustainability. Investments that bolster a state like Kentucky's coal-powered grid or revive polluting fossil fuel power plants can hardly be considered sustainable, environmentally, or socially responsible.

Instead, Fidelity and other companies can use financial clout to influence and incentivize a Bitcoin code change that virtually eliminates its climate and other environmental impacts aligning Bitcoin with many other cryptocurrencies that use dramatically less electricity. That's why we are calling on Fidelity to take responsibility for the Bitcoin pollution impacts on communities and support a code change to solve these growing problems at a global and local scale.

Join us in telling Fidelity's Chief Executive Officer Abigail Johnson to call for Bitcoin to change its code to use less energy and stop harming communities!
