Investing in carbon capture means choosing from a range of options: individual stocks of companies building capture facilities, ETFs focused on clean energy or climate solutions, carbon credit markets, or even crowdfunding platforms backing early-stage startups. The right entry point depends on how much risk you’re comfortable with and how directly you want your money tied to the technology itself.
Carbon capture is still an expensive, early-stage industry. Pulling CO2 directly from the air costs between $600 and $1,000 per ton right now, and even capturing it from factory smokestacks carries significant energy and capital costs. But government incentives are accelerating deployment fast, and the investment landscape is expanding.
Two Types of Carbon Capture Technology
Before putting money into this space, it helps to understand what you’re actually investing in. There are two broad approaches, and they sit at very different points on the cost and maturity curve.
Point-source capture grabs CO2 where it’s most concentrated: the exhaust streams of power plants, cement factories, and industrial facilities. Because the CO2 concentration is high, this approach is cheaper and more energy-efficient. It’s the more mature technology, with projects operating commercially for over two decades.
Direct air capture (DAC) pulls CO2 straight from the atmosphere, where it makes up only about 0.04% of the air. That dilution makes the process far more energy-intensive. Current DAC systems use either solid filters that operate at moderate temperatures (80 to 120°C) or liquid chemical solutions requiring extreme heat (300 to 900°C). DAC is the more ambitious technology, with higher costs but the potential to remove historical emissions, not just prevent new ones.
Publicly Traded Carbon Capture Stocks
A handful of companies offer relatively direct exposure to carbon capture through public stock markets. They range from pure-play technology firms to energy giants making large bets on the space.
Occidental Petroleum (OXY) is building the world’s largest direct air capture facility, called STRATOS, designed to extract 500,000 metric tons of CO2 from the atmosphere each year. Occidental plans to use captured CO2 partly for enhanced oil recovery, which makes this a bet on carbon capture bundled with traditional oil and gas economics. Warren Buffett’s Berkshire Hathaway holds a large stake, which has drawn attention to the stock.
Aker Carbon Capture (AKCCF) is a Norwegian company focused purely on carbon capture technology. It builds modular capture systems and is involved in projects like the Heidelberg Materials Brevik facility, which captures 400,000 tonnes of CO2 annually from cement production. As a pure-play company, Aker’s stock price tracks more closely with the carbon capture industry’s fortunes than a diversified energy company’s would.
Equinor (EQNR) has operated the world’s first dedicated CO2 storage site at the Sleipner field since 1996 and is a key player in Northern Lights, a large-scale CCS infrastructure project designed to store CO2 from multiple European industrial sources beneath the North Sea. Equinor is primarily an oil and gas company, so carbon capture represents just one piece of a much larger portfolio.
LanzaTech (LNZA) takes a different angle, using biotechnology to convert waste carbon emissions into fuels and chemicals through gas fermentation. It’s developing a CCUS project in Norway and represents a “carbon utilization” play, where the captured CO2 becomes a product rather than simply being stored underground.
ETFs and Funds
If picking individual stocks feels too risky in an industry this young, funds offer broader exposure. No major ETF focuses exclusively on carbon capture, but several sit along a spectrum from broad climate themes to more targeted holdings.
The Carbon Collective Climate Solutions U.S. Equity ETF (CCSO) is one of the more focused options, investing specifically in companies working on climate solutions. The VanEck Low Carbon Energy ETF (SMOG) covers low-carbon energy producers more broadly. For the widest net, funds like the iShares MSCI ACWI Low Carbon Target ETF (CRBN) or BlackRock’s U.S. Carbon Transition Readiness ETF (LCTU) hold companies across sectors that have lower carbon footprints or credible transition plans. These give you minimal direct carbon capture exposure but reduce your portfolio’s overall carbon risk.
Green bond ETFs are another option. The iShares Global Green Bond ETF (BGRN) holds fixed-income debt issued specifically to finance sustainable projects. You earn interest rather than equity returns, with lower volatility but also lower upside if the carbon capture industry takes off.
Carbon Credit Markets
Carbon credits represent a ton of CO2 either prevented from entering the atmosphere or removed from it. Investing in carbon credits is a more direct bet on the price of carbon itself rather than on any single company’s success.
The most accessible route for individual investors is through ETFs that hold carbon credit futures. These funds track the price of credits, like European Union Allowance futures traded on the ICE exchange, nearly one-to-one. They’re the riskiest category of carbon funds because they offer zero diversification, but they give you the most direct price exposure.
Buying carbon credit futures directly is technically possible for retail investors, but it’s complex and carries significant risk from leverage and price volatility. Directly investing in carbon offset projects is even harder, since most raise capital privately and aren’t open to small investors.
Early-Stage and Crowdfunding Options
Several crowdfunding platforms let smaller investors participate in climate technology projects that would normally require institutional capital. Platforms like Abundance Investment, Trine, and Ecoligo finance renewable energy and sustainability projects, offering returns from the project’s revenue. While most of these platforms focus on solar and wind rather than carbon capture specifically, the landscape is expanding as more capture startups seek early-stage funding outside traditional venture capital.
The trade-off is clear: early-stage carbon capture companies carry the highest risk of failure but offer the largest potential returns if the technology scales. Your money is typically locked up for years, and many of these companies have no revenue yet.
U.S. Tax Credits Driving the Industry
The economics of carbon capture investment changed substantially with the Inflation Reduction Act. The law’s Section 45Q tax credit pays $85 per metric ton of CO2 captured and stored in geological formations, and $180 per ton for direct air capture with storage. Projects need to begin construction before January 1, 2033, and can claim credits for up to 12 years once operational. The capture threshold for DAC projects is as low as 1,000 tons of CO2 per year, which opens the door for smaller facilities.
These credits don’t go directly to investors, but they dramatically improve the financial viability of capture projects. Companies building facilities can monetize credits through tax equity partnerships or transfer them under new IRA provisions, which makes their stock and project returns more attractive. When evaluating any carbon capture investment, the 45Q credit is essentially baked into the business model. A change in policy would significantly affect returns.
Key Risks to Understand
Carbon capture investing carries risks that go beyond normal market volatility. The technology is expensive. Even point-source capture requires heavy capital expenditure, and DAC costs remain five to ten times higher than most carbon pricing benchmarks. If costs don’t come down fast enough, many projects won’t be economically viable without subsidies.
Regulatory risk is substantial. The 45Q tax credits have bipartisan support for now, but a future Congress could reduce or eliminate them. Outside the U.S., carbon capture policy varies widely, and many countries lack the legal frameworks needed for CO2 transportation and underground storage.
Public perception is another factor. Some environmental groups oppose carbon capture because they see it as enabling continued fossil fuel use, particularly when captured CO2 is used for enhanced oil recovery. That opposition can slow permitting and project development. Infrastructure is also a bottleneck: captured CO2 needs pipelines to reach storage sites, and pipeline construction faces its own regulatory and community challenges.
Finally, most pure-play carbon capture companies are pre-profit or early-revenue. Stock prices can swing dramatically on a single project announcement or policy change. Treating this as a long-term, high-conviction allocation rather than a short-term trade is the more realistic approach for most investors.
