Bitcoin began as an idea shared by a small group of technology enthusiasts. In the last ten years, it has become a global digital asset. It draws interest from big investment firms, governments, and regular people.
Today, Bitcoin is not just a digital currency used for online payments. It is also seen as a new type of asset, similar to gold or stocks, that people can invest in. However, this transformation has come with significant challenges, particularly regarding energy use and environmental impact. As the Bitcoin mining industry matures, the focus is shifting toward more sustainable practices.
The Digital Pickaxe: How Bitcoin Mining Actually Works
In 2024, a major event for Bitcoin took place. The U.S. Securities and Exchange Commission (SEC) approved spot Bitcoin exchange-traded funds (ETFs). This decision made it much easier for regular investors and big institutions to buy and sell Bitcoin.
More companies and financial firms now offer Bitcoin to their clients. So, the digital asset is becoming more accepted in mainstream finance. Here’s how its market value compares with other cryptoassets and traditional assets.
Bitcoin depends on a process called “mining” to keep its network secure and to create new coins. Mining is done by powerful computers that solve complex math problems. When a computer solves a problem, it adds a new “block” to the Bitcoin blockchain. The miner then gets new bitcoins and transaction fees as a reward.
This process is called “Proof-of-Work.” It is designed to make sure that no one can cheat the system or take over the network. The more computers, or “hashrate,” that are working to mine Bitcoin, the more secure the network becomes.
Mining has changed a lot since Bitcoin started. At first, anyone with a home computer could mine Bitcoin. Now, most mining is done by large companies using special machines called ASICs (Application-Specific Integrated Circuits). These companies often have mining farms with thousands of machines running day and night.
The Cambridge Digital Mining Industry Report states that a recent survey covered 49 mining companies. These companies control almost half of the total computing power for Bitcoin mining. These companies operate in 16 countries. The United States is now the biggest mining hub, accounting for over 75% of mining activity.
The Energy Debate: Powering Bitcoin
One of the biggest debates about Bitcoin is how much energy it uses. Bitcoin mining is a high-energy process. Because mining requires so much computing power, it also needs a lot of electricity. Some people worry this might hurt the environment. This is a concern, especially if the electricity comes from fossil fuels like coal or natural gas.
The Cambridge report estimates that Bitcoin mining uses about 138 terawatt-hours (TWh) of electricity each year. This is similar to the annual electricity use of a country like Sweden.
- The mining activity also produces about 39.8 million metric tons of carbon dioxide (CO2) each year. However, this share of global emissions remained under 0.1%.
However, the report also shows that the energy mix for Bitcoin mining is changing. More than half (52.4%) of the electricity used by miners now comes from sustainable sources. This includes hydropower (23.4%), wind (15.4%), nuclear (9.8%), and solar (3.2%). Still, natural gas remains the single largest energy source at 38.2%, followed by coal (8.9%).
Many mining companies are trying to use more renewable energy and to find ways to reduce their environmental impact. Some are even using energy that would otherwise be wasted, such as gas flaring from oil fields. These efforts are important as the industry faces growing pressure to be more environmentally friendly.
Meanwhile, the survey shows a possible scenario when miners want to offset the emissions of their activities by buying carbon credits. The chart below compares the cost of removing Bitcoin’s carbon emissions using two methods: nature-based solutions like planting trees, and high-tech solutions like direct air capture (DAC).
Nature-based methods cost about $5 to $9 per ton of CO2, while DAC costs much more—between $134 and $344 per ton. Lower emissions mean lower total costs, and higher emissions mean higher total costs for offsetting.
Wall Street Meets Blockchain: Institutions Dive In
Bitcoin’s price has seen big changes in recent years. In early 2025, Bitcoin reached a new high of about $109,000 before dropping to around $74,000 in April. By May, it had recovered to about $95,000. These price swings show how quickly the market can change.
However, the broader market trend shows growing maturity:
- Institutional adoption is rising. Major firms—including BlackRock, Fidelity, and MicroStrategy—have invested directly in Bitcoin or launched crypto-related products.
- Spot Bitcoin ETFs approved in early 2024 have brought mainstream exposure, unlocking billions in capital inflows.
- Bitcoin’s market cap briefly surpassed $1.5 trillion in early 2025, signaling continued investor interest even amid macroeconomic uncertainty.

Experts have different predictions for where Bitcoin’s price will go next. Some believe it could reach $150,000 or even $200,000 by the end of 2025, especially as more institutional investors enter the market.
The approval of Bitcoin ETFs has made it easier for large funds and retirement accounts to invest in Bitcoin. Even a small investment from these big players could have a big impact on Bitcoin’s price.
The growing interest from companies is also important. Some businesses, like MicroStrategy, have bought large amounts of Bitcoin as a way to store value. This shows that Bitcoin is being used not just as a currency, but as a financial asset.
These trends point to Bitcoin’s growing acceptance as both a store of value and a portfolio diversifier. This financial legitimacy is helping drive the push toward more sustainable and compliant mining practices. And one name stands out in this direction – American Bitcoin Corp.
Stars, Stripes, and Satoshis: The Rise of American Bitcoin
American Bitcoin Corp. is a majority-owned subsidiary of Hut 8 Corp., one of North America’s leading digital asset mining companies. In early 2025, Hut 8 teamed up with American Data Centers to launch American Bitcoin. This partnership includes investors Eric Trump and Donald Trump Jr. American Bitcoin will focus on large-scale Bitcoin mining and creating a strategic Bitcoin reserve.
Hut 8 serves as American Bitcoin’s exclusive infrastructure and operations partner. American Bitcoin uses Hut 8’s strong data center skills, energy setup, and large-scale operations. They do this through long-term business agreements.
Hut 8’s CEO, Asher Genoot, highlights that separating American Bitcoin helps it raise growth capital on its own. This move also keeps Hut 8 shareholders connected to Bitcoin’s potential gains.
Just recently, American Bitcoin announced a merger with Gryphon Digital Mining. This stock-for-stock deal will take them public. They plan to trade on Nasdaq with the ticker symbol “ABTC.” This move aims to scale American Bitcoin as a low-cost Bitcoin accumulation vehicle, unlocking new capital to expand mining capacity and Bitcoin holdings.
The combined company will be led by a board including Hut 8 CEO Asher Genoot and other key executives such as Mike Ho and Eric Trump. American Bitcoin aims to be the largest and most efficient Bitcoin miner globally. They plan to achieve over 50 exahashes per second (EH/s) of mining power. Their goal is also to maintain an average fleet efficiency below 15 joules per terahash (J/TH).
By combining Hut 8’s operational excellence and infrastructure with strategic capital and market access, American Bitcoin is positioned to lead the U.S. Bitcoin mining industry and build a robust Bitcoin reserve for long-term growth.
Hurdles on the Hashrate Highway
Bitcoin’s future hinges on overcoming several key challenges. Regulatory uncertainty is a big problem. Governments have different rules for digital assets, which makes it hard for mining companies to plan for the long term.
Energy costs are a big concern. Mining only makes money when Bitcoin’s price is higher than electricity and equipment costs. If energy prices keep rising, miners might lose and shut down.
Additionally, as more miners join, mining becomes harder and requires continuous equipment upgrades to remain competitive. Environmental impact remains a concern, but innovations like AI are improving efficiency.
Despite these challenges, Bitcoin mining continues to evolve, with new technologies emerging to enhance sustainability and possibly even support power grids. The balance between growth and these hurdles will shape Bitcoin’s future in the global economy.

The post Bitcoin’s New Gold Rush: ETFs, Energy Battles and the Rise of American Bitcoin appeared first on Carbon Credits.
For most businesses, the emissions that matter most sit outside their own walls. Scope 3 emissions, everything generated across your value chain, from the suppliers who make your inputs to the customers who use your products, typically make up the majority of a company’s total carbon footprint. Under the Corporate Sustainability Reporting Directive (CSRD), those value-chain emissions now have to be measured and disclosed with a rigour that spend-based estimates alone struggle to satisfy. This guide sets out how to improve Scope 3 data accuracy for CSRD: the calculation methods open to you, how to move from estimates to verified supplier data, and how to govern that data so it holds up to audit.
A carbon credit is a commitment that extends well into the future. The tonne of CO₂ compensated for today from a nature-based carbon project must remain out of the atmosphere for good, which means the forest behind the credit has to remain standing long after the transaction is complete. For any buyer, this raises a defining question: What ensures that the forest endures?
What replaced the cheap REDD credit on the boardroom slide deck, and why procurement is leading the rewrite.
Three years ago, a corporate slide showing a portfolio of cheap REDD+ credits could carry a board meeting. The number was big, the price was low, and the press release wrote itself. Today, that same slide gets sent back with questions. The questions are uncomfortable, the answers are unclear, and your general counsel is suddenly in the room.
Conventional carbon offsets are not dead. The voluntary carbon market retired 202 million tonnes in 2025, and the Morgan Stanley Institute for Sustainable Investing survey published in January 2026 confirmed that interest from corporate buyers remains substantial. What changed is the credibility threshold. The integrity floor has risen, the disclosure scrutiny has tightened, and the buyer profile has shifted. This article tracks what changed, what sophisticated buyers now ask before signing, and what serious corporates are putting on the board slide instead.
What boards used to buy, and why it stopped working
The 2020 to 2022 model was simple: buy a large tranche of avoidance credits at low single-digit prices, retire them against the company footprint, announce the carbon-neutral claim, and move on. Most of those credits came from REDD+ projects, renewable energy installations in countries where the renewable energy was already economic, or methane projects with thin documentation.
Several things broke that model. Academic research published in 2023, including a widely cited Science paper, found that the majority of REDD+ credits issued under the most common methodologies did not represent additional reductions when tested against rigorous counterfactuals. The Voluntary Carbon Markets Integrity Initiative published its Claims Code of Practice, which sets requirements for what companies can credibly claim from credit use. The European Union finalised its Green Claims Directive, restricting how companies can describe products as climate-neutral. France’s Décret 2022-539 already restricts carbon neutrality advertising. California’s AB 1305 imposes disclosure requirements on any company making net-zero or carbon-neutral claims while doing business in the state.
The collective effect: the cheap credit no longer buys the announcement, and the announcement now carries litigation risk.
The integrity reset: ICVCM, VCMI, and what changed
The Integrity Council for the Voluntary Carbon Market published the Core Carbon Principles in 2023 and began assessing methodologies against them in 2024. The first methodologies received the CCP label later that year. The point of the label is to give corporate buyers a defensible quality screen they can cite in disclosure.
The Voluntary Carbon Markets Integrity Initiative complements this on the demand side. Its Claims Code of Practice defines what a buyer can say (Silver, Gold, or Platinum claims, with associated requirements) based on the quality of credits used and the underlying decarbonisation strategy. Together, CCP and VCMI build a quality stack: CCP on the supply, VCMI on the claim, with the science-based target sitting underneath both.
The reset is not a ban on offsets. It is a ratchet. Credits that meet the new bar continue to clear; credits that do not, do not. The Morgan Stanley survey found that 61% of current buyers like the CCP label concept but that supply of labelled credits remains limited. That supply constraint is now visible in pricing.
What sophisticated buyers ask before they sign
The questions on the procurement scorecard have changed. A 2022 buyer might have asked about price, vintage, and project type. A 2026 buyer asks five different questions before any of those.
- What does the counterfactual look like, and who validated it.
- What is the permanence regime, and what is the buffer pool exposure.
- What is the leakage risk, and how is it mitigated.
- What rating has the project received from the independent ratings agencies (Sylvera, BeZero, Calyx Global), and what was the rationale.
- What is the documentation discipline that survives an audit four years from now when the procurement team that signed the contract has moved on.
If the vendor cannot answer those five questions on a first call, the conversation ends. Conversely, if the vendor can answer them with documented specificity, the conversation often expands beyond a single transaction toward a multi-year engagement.
Where this leaves your near-term commitments
You probably have near-term commitments that pre-date the integrity reset. Public targets to be carbon neutral by 2025 or 2030. Product-level claims that ran in last year’s marketing. Disclosed reduction trajectories that assumed continued access to cheap credits.
You have three workable paths. The first is to re-baseline your strategy, replacing the most exposed credits with higher-quality alternatives and adjusting the public language to match what you can defend. The second is to shift the underlying spend from offsetting outside your value chain to investing inside your value chain, where reductions count against Scope 3 directly and the audit trail is cleaner. The third is to keep the strategy and absorb the risk, which is increasingly the most expensive option once you price in litigation, restatement, and reputational exposure.
Most serious buyers are choosing the second path. It moves the carbon spend from a compliance cost to a procurement and resilience investment, and it removes the central failure point of the legacy model: the disconnect between where the emissions occurred and where the reductions sat. Nature-based supply chain investments, structured under the GHG Protocol Land Sector and Removals Standard and aligned to the SBTi FLAG Guidance, are the asset class that fits this brief. They generate inventory-grade reductions, they produce audit-grade documentation, and they survive the new claim restrictions because the carbon math sits inside the value chain that the disclosure already covers.
If you are reassessing a carbon strategy under the new integrity bar, or rebuilding a board narrative that has to survive a more skeptical audience, the carbon and sustainability experts at Carbon Credit Capital can help. The Dual-Value Model gives you a defensible alternative to legacy offset purchases, with the documentation and operational integration that survives the procurement scorecard and the audit.
