The EU Carbon Market Is on Fire: A Deep Dive Into ETS in 2026
EU carbon prices are surging past €80/tonne with supply tightening 8% in 2026. Here's what's driving the rally, what the reforms mean, and why this market matters more than ever.
The Carbon Market Nobody's Talking About
While everyone's busy debating AI stocks and crypto, there's a $114 billion market that's been quietly surging — and it could be one of the most important asset classes of the decade.
I'm talking about carbon credits. Specifically, the European Union's Emissions Trading System (EU ETS), the world's oldest and largest carbon market.
EU carbon allowances hit €83.79 per tonne in late 2025, posting five consecutive months of gains and a 30% year-over-year increase. And here's the thing — the supply of allowances available in 2026 is about to drop 8% compared to 2025.
Basic economics: less supply + same or growing demand = higher prices.
Let me walk you through what's happening, why it matters, and what I think comes next.
What Is the EU ETS, Exactly?
The EU Emissions Trading System, launched in 2005, is essentially a cap-and-trade program. The EU sets a cap on total emissions from power plants, factories, and airlines. Companies within the system receive or buy emission allowances — one allowance equals one tonne of CO2.
If a company emits less than its allowances, it can sell the extras. If it emits more, it has to buy more on the open market. The cap tightens every year, making allowances progressively scarcer.
The system has been remarkably effective. By end of 2024, greenhouse gas emissions covered by the ETS had declined 47% compared to 2005 levels. And it's raised over €245 billion in revenue that member states can reinvest in climate action.
What's Driving the 2025-2026 Rally?
Three main forces are converging:
1. Gas/Carbon Decoupling
This is huge. Historically, EU carbon prices moved in lockstep with natural gas prices — when gas was expensive, utilities burned more coal, which increased demand for carbon allowances. But in late 2025, something changed.
Carbon prices kept climbing even as the energy crisis eased. The carbon market is now being driven by its own supply-demand dynamics, not just energy markets. Investment funds have increased their long positions to all-time records, signaling serious institutional confidence.
2. Supply Tightening
The math is simple. In 2026, the supply of allowances drops roughly 8% from 2025 levels. This happens because:
- Frontloading auctions from the REPowerEU plan are ending
- CBAM (the carbon border tax) is replacing free allowances
- The linear reduction factor keeps cutting the overall cap
Less supply hitting the market means structural upward price pressure.
3. The 2040 Climate Target
The European Commission has proposed an ambitious 90% emission reduction by 2040 compared to 1990 levels. If adopted, this would require a dramatically steeper decline in allowances over the next 15 years. Markets are starting to price in this long-term scarcity.
The Numbers: Where Prices Are Heading
Here's what the forecasters are saying:
| Year | Projected Price (€/tonne) | Source |
|---|---|---|
| 2026 | €85 (+18% YoY) | Consensus |
| 2027 | €100+ | Enerdata |
| 2028 | €110-120 | Various |
| 2030 | €126-149 | GMK/BNEF |
The spread between forecasts is wide — ranging from €80 to €147 for 2030 — which tells me there's genuine uncertainty about how fast decarbonization will happen. But the direction is clear: up.
The Big Reforms Coming
EU ETS Review (2026)
The European Commission launched public consultations in 2025 for a major ETS review scheduled for 2026. Key changes being discussed:
-
Market Stability Reserve (MSR) overhaul: The MSR is the mechanism that absorbs excess allowances when supply is too high. There's talk of redefining thresholds, changing intake rates, and potentially creating a "European Carbon Bank" for more active market management.
-
UK-EU ETS linkage: On May 19, 2025, the UK and EU announced plans to link their carbon markets. This would create an even larger, more liquid trading pool.
-
International carbon credit integration: The 2040 target proposal includes an option to use international carbon credits for up to 3% of reductions — a nod to the Paris Agreement's Article 6 mechanisms.
ETS 2: Buildings & Transport (Delayed to 2028)
The EU was supposed to launch a second ETS covering buildings and road transport in 2027, but in November 2025, the Council postponed it to 2028. Interestingly, markets read this as bullish — viewing it as a credible political compromise that signals long-term stability rather than rushed implementation.
Sectoral Expansion
The Commission is also exploring:
- Extending ETS to smaller ships (maritime)
- Evaluating CORSIA effectiveness for aviation (report due mid-2026)
- Potentially bringing more industrial processes under the cap
My Take
I think the EU ETS is one of the most underappreciated markets in global finance right now. Here's why:
The structural case is rock solid. Supply is mechanically tightening every year. The cap ratchets down by law. Political commitment to the 2040 target gives long-term price visibility that few other commodity markets can match.
Institutional money is piling in. When investment funds are building record-long positions, that's not speculation — it's conviction. These are sophisticated players who understand the regulatory trajectory.
The decoupling from gas is a game-changer. Carbon is becoming its own asset class with its own price dynamics. That maturation attracts more capital, which creates a positive feedback loop.
That said, I have concerns:
Regulatory risk is real. The 2026 review could go either way. If politicians get spooked by energy costs or industrial competitiveness fears, they could loosen the cap or flood the market with allowances. Unlikely, but possible.
The price has already run up significantly. At €83+, we're not at the ground floor anymore. A pullback to the €70s wouldn't surprise me before the next leg higher.
Liquidity isn't great for retail. This isn't like buying Apple stock. Carbon futures are complex instruments with specific contract specifications and margin requirements.
The Bottom Line
The EU carbon market is entering its most transformative period yet. Supply is tightening, demand is structural, institutional money is flowing in, and the regulatory trajectory points firmly upward.
If you're thinking about portfolio exposure to the energy transition, carbon credits deserve serious consideration alongside solar stocks, EV plays, and green bonds. The EU ETS isn't just an environmental policy tool anymore — it's becoming a major financial market with a clear long-term price trend.
