How to Actually Invest in Carbon Credits in 2026
The global carbon market hit $114.3B in 2025 and is projected to reach $482B by 2035. Here's a practical guide to the ETFs, futures, platforms, and strategies available to investors who want exposure to carbon credits — plus the risks you need to understand.
From Theory to Portfolio: Investing in Carbon
Over the past few articles in this series, I've covered the EU ETS, global carbon markets, CBAM, and the voluntary carbon market. Now let's get practical.
The question I hear most often is: "This all sounds compelling, but how do I actually get exposure to carbon credits?"
It's a fair question. Unlike buying Apple stock or an S&P 500 index fund, investing in carbon credits isn't straightforward. The market infrastructure is still evolving, the products are specialized, and there are real complexities to navigate.
But the opportunity is real. The global carbon market hit $114.3 billion in 2025 and is projected to reach $482 billion by 2035. That kind of growth trajectory deserves a spot on any forward-thinking investor's radar.
Let me walk you through the options, from most accessible to most specialized.
The Investment Landscape: Compliance vs. Voluntary
Before diving into specific products, you need to understand the two distinct arenas you can invest in.
Compliance markets (EU ETS, California Cap-and-Trade, RGGI) are where the big money is. These are regulated, liquid, and structurally supported by government mandates. When I talk about the carbon market being $114.3 billion, I'm mostly talking about compliance markets. Prices here are driven by supply caps that tighten by law, which gives them a level of price floor support that most commodities lack.
Voluntary markets are smaller (~$1.6-2.5 billion), less regulated, and more fragmented. The opportunity here is potentially higher returns due to the market's earlier stage, but the risks — quality concerns, less liquidity, no regulatory backstop — are also higher.
Most retail investors should start with compliance market exposure. It's more accessible, more liquid, and has clearer long-term price drivers.
Option 1: Carbon ETFs (Most Accessible)
If you have a brokerage account, you can buy a carbon ETF as easily as you'd buy any other stock. This is by far the simplest way to get carbon exposure.
KraneShares Global Carbon ETF (KRBN)
KRBN is the flagship carbon ETF and the product most retail investors will encounter first. It tracks the IHS Markit Global Carbon Index, which includes carbon allowance futures from:
- EU ETS (the dominant weight)
- California Cap-and-Trade
- RGGI
You buy it on the NYSE like any other ETF. It gives you broad carbon market exposure in a single ticker. It's the product I'd point most beginners toward.
What to know:
- KRBN invests in carbon allowance futures, not physical allowances, which introduces roll costs and tracking error
- The fund is heavily weighted toward the EU ETS, so its performance is largely driven by European carbon prices
- Expense ratio matters — check the current fee and compare it to alternatives
- Like any futures-based product, contango (when futures prices are higher than spot) can create a drag on returns over time
iPath Series B Carbon ETN
Exchange-traded notes (ETNs) are another route. Unlike ETFs, ETNs are debt instruments — you're lending money to the issuer, who promises to pay you a return linked to a carbon index. This means you carry the credit risk of the issuer in addition to carbon market risk.
ETNs can sometimes track carbon benchmarks more closely than ETFs because they don't deal with the complexities of physically holding futures contracts. But the added credit risk is a real consideration.
Other Carbon ETFs
The ETF landscape is evolving. There are now products that focus on specific carbon markets (EU-only, California-only) and others that blend carbon with broader climate-related investments. The space is still small enough that KRBN dominates, but competition is growing.
Option 2: Carbon Futures (More Sophisticated)
For investors comfortable with derivatives, trading carbon futures directly on exchanges like ICE (Intercontinental Exchange) gives you the purest exposure.
EU carbon allowance futures (EUA futures) trade on ICE Endex. California carbon allowance futures trade on ICE as well. These are standardized contracts with defined expiration dates, and they're what institutional investors and compliance buyers actually use.
Why consider futures:
- Most direct price exposure — no tracking error from ETF structure
- Leverage available (can be used prudently or dangerously)
- Highly liquid in the EU ETS market
- No management fees
Why be cautious:
- Futures require a margin account and understanding of contract specifications
- Contracts expire — you need to roll positions, which has costs
- Leverage amplifies losses just as readily as gains
- Not suitable for passive, set-it-and-forget-it investing
- Minimum position sizes may be too large for small accounts
I'd only recommend direct futures trading for investors who already have experience with commodity futures or derivatives. If you're new to futures, start with an ETF.
Option 3: Specialized Carbon Platforms
A growing number of platforms are specifically designed to make carbon credit investing accessible to retail investors. These range from marketplace-style platforms where you can buy and hold carbon credits directly to fintech apps that let you invest in carbon portfolios.
Some platforms focus on compliance allowances, letting you buy actual EU or California allowances in smaller increments than the futures market would allow. Others focus on voluntary credits, offering portfolios of verified carbon offsets.
What to look for:
- Regulatory status and investor protections
- Fee structure (transaction fees, custody fees, spread)
- What you actually own — some platforms sell credit-linked tokens or derivatives rather than actual allowances
- Liquidity — can you sell when you want to?
- Track record and counterparty risk
This space is still maturing. Conduct thorough due diligence on any platform before committing capital.
Option 4: Private Carbon Funds
For accredited or institutional investors, private funds focused on carbon credits have been emerging. These funds typically take a more active approach — buying allowances, investing in carbon credit projects, or executing strategies that aim to capture specific carbon market dynamics.
Some focus on the compliance-voluntary arbitrage. Others invest directly in CDR technology companies or carbon credit originators. A few are structured as venture capital funds targeting early-stage carbon market infrastructure.
The minimum investments are typically substantial (six figures and up), and the lock-up periods can be long. But for investors with the capital and time horizon, these funds offer exposure to parts of the carbon market that retail products can't easily reach.
Carbon as a Portfolio Diversifier
One of the most interesting aspects of carbon credits as an investment is their diversification potential. Historical data shows that carbon allowance prices have exhibited low correlation with traditional equity and bond markets.
This makes intuitive sense. Carbon prices are driven by regulatory decisions, weather patterns (which affect energy demand), industrial output cycles, and climate policy developments — factors that don't neatly align with what drives stock prices.
For portfolio construction, an asset with genuine diversification benefits — one that zigs when stocks zag — is valuable. Adding a small carbon allocation to a traditional 60/40 stock-bond portfolio could improve risk-adjusted returns over time.
That said, I want to be careful with this argument. Carbon is a young asset class with a limited price history. The low correlation to stocks might not hold during systemic market stress. And the regulatory risk profile is unlike anything else in a typical portfolio. Treat diversification as a potential benefit, not a guarantee.
The Bull Case for Carbon Prices
Let me lay out why many investors and analysts are structurally bullish on carbon:
Supply is mechanically tightening. In compliance markets, the cap on allowances ratchets down every year by law. This creates predictable, increasing scarcity — something almost no other commodity can claim.
Demand is structural. Companies need allowances to operate. This isn't discretionary demand — it's compliance-driven.
Political commitment is deepening. The EU's 2040 target (90% emission reduction), CBAM's implementation, and the proliferation of national carbon pricing systems all point toward higher prices.
EU ETS prices are projected to hit $100+ by 2027. Most forecasters see continued upward momentum, with targets of $126-149 by 2030.
The market is growing. From $114.3 billion today to a projected $482 billion by 2035 — the overall pie is getting much bigger, which should attract more capital and liquidity.
The Risks: What Could Go Wrong
I'd be irresponsible if I didn't lay out the risk factors just as clearly as the bull case.
Regulatory Risk
This is the big one. Carbon markets exist because governments created them. What governments create, they can modify or dismantle. A shift in political priorities — recession fears, competitiveness concerns, changes in government — could lead to looser caps, more free allowances, or even policy reversal.
I think this risk is lower in the EU than elsewhere (carbon pricing has deep institutional support), but it's never zero. In the US, state-level programs are more vulnerable to political shifts.
Price Volatility
Carbon prices can be volatile. EU allowances have swung from $30 to $100+ in recent years. This isn't a stable, income-producing asset — it's a commodity with policy-driven supply dynamics. If you can't stomach a 30-40% drawdown, carbon isn't for you.
Liquidity Risk
While the EU ETS is liquid, smaller markets (RGGI, voluntary markets, emerging market systems) can have thin trading volumes. Getting in is one thing — getting out at a fair price when you need to can be another.
Product Complexity
ETFs based on futures contracts behave differently from spot exposure. Roll costs, contango, and tracking error can significantly impact returns. Make sure you understand the product mechanics before investing.
Oversupply Scenarios
If economic recession dramatically reduces industrial output — and therefore emissions — demand for allowances could drop faster than supply adjusts. The Market Stability Reserve in the EU ETS is designed to prevent this, but it's not a perfect buffer.
Practical Tips for Getting Started
If I were advising someone looking to add carbon exposure to their portfolio for the first time, here's what I'd suggest:
1. Start small. A 3-5% portfolio allocation to carbon is more than enough for most investors. You can always increase it as you get more comfortable with the asset class.
2. Begin with a carbon ETF. KRBN or a similar product gives you diversified compliance market exposure with the simplicity of buying a stock. You don't need futures accounts or specialized platforms to get started.
3. Understand what you own. Read the ETF prospectus. Know which markets are included, how futures rolling works, and what the fee structure is. This isn't a "buy and forget" asset class.
4. Think long-term. The structural case for carbon prices is a multi-decade thesis tied to the global energy transition. Short-term trading around policy announcements is a game for specialists.
5. Watch the regulatory calendar. EU ETS review decisions, CBAM implementation updates, national carbon pricing launches — these events move markets. Stay informed.
6. Don't over-concentrate. No matter how bullish you are on carbon, it should be one component of a diversified portfolio. Regulatory risk alone justifies position sizing discipline.
7. Consider the tax implications. Carbon futures and ETFs may have different tax treatments depending on your jurisdiction. Consult a tax professional, especially for direct futures positions.
My Take
I think carbon credits represent one of the most interesting asymmetric opportunities in markets today. The structural tailwinds — tightening supply, deepening policy commitment, market expansion — are powerful and measurable. And the asset class offers genuine portfolio diversification.
But I also think it's an asset that requires more homework than most. The product landscape is still developing. The regulatory risk is real and unique. And the complexities of futures-based investing can trip up newcomers.
My bottom line: educate yourself first, start with accessible products, size your position conservatively, and think in terms of years, not quarters. The global energy transition is a multi-decade megatrend, and carbon pricing is at its center.
The $114.3 billion market of 2025 is heading toward $482 billion by 2035. I want to be positioned for that growth. I think you should consider it too.
The Bottom Line
Carbon credits are no longer a niche curiosity — they're becoming a legitimate asset class with real infrastructure, growing liquidity, and a structural growth story that few other markets can match. Whether through ETFs, futures, platforms, or funds, the entry points for investors have never been better or more varied.
The key is matching your investment vehicle to your knowledge level, risk tolerance, and time horizon. Start simple, stay disciplined, and keep learning.
This wraps up our five-part carbon credits series. If you've followed along from the EU ETS deep dive through global markets, CBAM, and the voluntary market, you now have a comprehensive foundation for understanding and participating in one of the most important markets of the decade.
