Understanding EU ETS carbon prices in 2026 means, first of all, grasping why the Dec-2026 benchmark can move quickly even without “definitive news”. At the end of February 2026, the Dec-2026 benchmark contract fell to around ~€70/t, with an OPIS assessment at about €69.82/t, after the mid-January highs. According to OPIS, the market is simultaneously pricing in compliance demand and policy uncertainty, and this can amplify price moves.
Why EU ETS prices are falling: the factors that really matter (industrial demand, gas, renewables, weather)
The most direct driver is expected compliance demand. When the market senses that verified emissions could come in lower, it tends to reduce the urgency to buy EUAs on spot and forward. This is most visible in hard-to-abate sectors such as steel, cement, and chemicals, where industrial output is a practical proxy for emissions: less output, less CO₂, fewer allowances to buy (all else equal, including free allocation and existing inventory).
Industrial demand also matters for a “buyer-side” reason. If production declines, the EUA coverage needed drops almost mechanically because surrender is tied to verified emissions. In practice, a procurement team can recalibrate its buying plan: fewer volumes to cover in the short term, more flexibility on when to enter the market.
In power, the link runs through fuel switching. The EUA price is intertwined with gas and coal via generation margins (spark vs dark spread): if gas is relatively more expensive, coal generation can increase and so can EUA demand; if gas is cheaper and/or renewables cover more hours, fossil generation falls and EUA demand tightens. This is the classic case where a utility desk rebalances power hedging and carbon hedging together, because expected fossil running hours change.
Renewables and weather act as an accelerator. Weeks with low wind in Germany can shift more hours to coal and raise EUA demand; a mild winter reduces heating demand and can do the opposite, cutting fossil hours and therefore the need for allowances. Here too, the market prices expectations, not only ex-post data.
Finally, there is the political risk premium. OPIS links the sell-off also to “policy uncertainty”: when discussions circulate about possible adjustments or reforms, some participants reduce long exposure and the price can fall faster, even if physical fundamentals have not changed on the same day.
What tools the Commission has to “stabilise” the EU ETS: MSR, auctions, cap and intervention rules
The most important lever in the ETS design is the Market Stability Reserve (MSR). The mechanism works on thresholds: if the total number of allowances in circulation (TNAC) exceeds the upper limit, a share of future auctions is withheld and placed in the reserve; if it falls below the lower limit, the reserve releases allowances to the market. The MSR is not a price-control tool, but a tool to manage structural supply. For the market, this translates into an implicit floor as scarcity approaches, but also uncertainty on auction timing and volumes when thresholds are hit.
The second lever is the auction calendar and auction volumes, which are part of market microstructure. On the common auction platform, EEX indicates for 2026 indicative volumes of around 408,235,500 EUAs; for Germany about 73,563,500 and for Poland about 48,705,500. Relevant technical note: volumes for September–December 2026 may be subject to MSR adjustments (Art. 14 of the Auctioning Regulation). For a buyer, this means perceived supply is not “flat” and can change through the year.
The cap and its trajectory make the price more sensitive to shocks. The key point, also discussed in ETS design literature, is that tools such as the LRF (Linear Reduction Factor) and rebasing (one-off reductions) tighten availability over the medium term. So you can have short-term pressure from the industrial cycle or weather, but a structural scarcity that remains in the background and re-emerges when demand rebounds.
There is also the REPowerEU/RRF channel. The Commission signals a REPowerEU 2026 volume adjustment of 93,280,000, with the logic of auctions until reaching €20 billion by 31 August 2026. Even without “price control”, this can influence expectations and volatility because the market watches the calendar and the quantity.
Above all, interventions are not discretionary in the sense of “controlling the price”. They occur through rule-based mechanisms (MSR, auction adjustments) or via legislative revisions that require an institutional process. In practice: some things can change via rules already in force, others require the European Parliament and the Council.
What to expect in 2026: price scenarios and the main triggers that could reverse the trend
The most closely watched trigger is the regulatory timeline. OPIS reports that a formal review of ETS functioning is expected in Q3 2026, and that even rumours or leaks about possible slowdowns in the phase-out of free allocation have weighed on prices. Even the expectation of change can move the market, because it feeds into the political risk premium.
In the bull case, catalysts are energy and macro: higher gas, low renewable output, a cold winter, industrial recovery. In these scenarios, fossil generation increases and compliance demand rises. Operationally, a utility may increase EUA hedging when expected load rises and the wind profile deteriorates, because it anticipates more fossil marginal hours.
In the bear case, weak industrial output, abundant renewables, cheaper gas, and a higher political risk premium matter. For risk management, indicators such as futures open interest, fund flows, and implied volatility become useful, because they signal how much “positioning” is supporting the price.
For budgeting, it makes sense to work with a scenario range, not a single point estimate. A working interval such as €60–€100/t can be used to build carbon-cost sensitivity per tonne of product, combining the emissions factor and the remaining share of free allocation. Here, EU ETS carbon prices in 2026 become a control variable for margins and pricing, not just a chart to watch.
Compliance seasonality is another trigger. The compliance season between Q1 and Q2, with surrender typically in spring, can concentrate demand and liquidity. For procurement, the practical rule is to avoid concentrating purchases close to deadlines, if governance allows.
What impact lower prices have on companies and investors: compliance costs, hedging and allowance purchasing strategies
The first impact is on compliance cash-out. The basic formula for CFOs and controlling is simple: EUA price × verified emissions minus free allocation, plus any opportunity cost of using allowances already held in inventory. A useful example: a plant with 500k tCO₂/year sees a -€10/t move translate into roughly -€5 million in potential cash-out, all else equal.
On the hedging side, lower prices can become a window to cover future years. Typical strategies include forward futures (e.g., Dec-26/Dec-27), rolling hedges, and layered hedging. The practical question remains: buy spot or lock in forward? The answer depends on basis risk, margins, collateral, and internal rules—not only on a market view.
This is where a clear procurement policy is needed. VaR limits, trigger prices, buying windows, and governance with a risk committee help avoid turning compliance into trading. Useful KPIs: average EUA cost, coverage percentage at 6/12/24 months, tracking versus an internal benchmark.
For investors, lower prices reduce carry for those who are structurally long, but increase optionality if future tightening is expected via the cap, LRF, and MSR. The read-through comes from the forward curve (contango/backwardation), volatility, and sensitivity to policy headlines.
Finally, auctions are liquidity events. The EEX 2026 volumes provide a concrete reference to understand why certain weeks can feel “heavier” on supply and why a compliance buyer may alternate between auctions and the secondary market to improve execution.
EU ETS and ETS2: how the launch of the new system can influence expectations and carbon price volatility in Europe
ETS1 and ETS2 should be kept separate. The “historic” EU ETS covers power, industry, and other sectors within scope; ETS2 is a distinct system for fuels used in buildings and road transport, with auctions starting from 2027. It is not “the same EUA”, but it can influence sentiment and the political narrative around carbon pricing, as also highlighted in European Parliament materials (an EU institution).
In 2026, attention increases because the ETS2 monitoring period starts on 15 July 2026, while operational auctions begin in 2027, according to Carbon Market Watch. This puts operator readiness on the table (especially fuel suppliers) and potential discussions about delays.
There is also a postponement clause: ETS2 can be delayed to 2028 if, in 2026, conditions linked to high gas or oil prices occur—politically sensitive and potentially market-moving.
The interaction with expectations for ETS1 is mainly psychological and political. On one hand, expanding carbon pricing can strengthen the long-term narrative; on the other, it can increase the perceived risk of “softening” if social pressure over energy prices rises. This too feeds into the risk premium that can weigh on EU ETS carbon prices in 2026.
Tokenisation and finance angle: be careful not to confuse regulatory units and voluntary credits. ETS2 creates new MRV and reporting needs along the fuel supply chain, and this is where digital tools for traceability, data quality, and audit trails can have a role—without turning the EUA into a “carbon credit”.
How to monitor the key signals (auction calendar, EEX data, EU decisions) to anticipate price moves
The auction calendar is an immediate operational signal. The Commission indicates the frequency: common platform on Monday, Tuesday and Thursday from 8 January 2026; Germany on Fridays; Poland on one Wednesday every two weeks; Northern Ireland auction on 7 October 2026. These appointments are microstructure events: they change liquidity and often influence execution timing.
EEX datasets are the foundation for a procurement-style approach. On EEX you can find the auction calendar (PDF/XLS) and auction results with clearing price and volumes. You can use them to plan purchases while avoiding low-liquidity days, compare clearing versus secondary market, and estimate remaining supply, including potential MSR-related shocks.
On the EU side, consultations, statements, and any indication of calendar adjustments should be monitored. In 2026, with attention on the review expected in Q3, even a weak signal can move the price.
A cross-market dashboard is also needed: TTF gas, clean dark/spark spreads, wind and hydro output, weather (degree days), and power demand. Setting quantitative alerts on TTF, wind, and spread thresholds helps connect fundamentals to EUA demand.
Checklist (B2B) for a typical week:
- Check the EEX auction calendar and results.
- Monitor EU headlines and signals on ETS.
- Update the weather and renewables scenario.
- Recalculate hedge coverage and collateral.
- Decide whether to buy at auction, OTC, or on-exchange, using best-execution logic and governance.
