Why trading activity jumped in the first quarter and what changed in the market

EEX carbon futures volumes appear to have surged in Q1 2026 because the market is pricing a tighter policy path, stronger hedging demand, and more active discretionary trading at the same time. That is more consistent with a structural shift than a one-off spike.

Q1 2026 carbon trading sits inside a broader EU ETS backdrop that is still described by the European Commission as “well-functioning,” but also more sensitive to forward positioning. The Commission’s 2025 Carbon Market Report points to cap adjustments taking effect in 2026, including rebasing and maritime-related scope changes, which can pull compliance buyers and intermediaries further out on the curve. The Market Stability Reserve also keeps removing supply when the TNAC is above 1,096 million allowances, which reinforces the market’s policy-defined scarcity and helps explain why participants hedge earlier.

EEX’s own 2025 numbers show that the market was already building momentum before this quarter. It reported 1,316.3 million tonnes of CO2 traded in environmental products in 2025, and said December 2025 European EUA futures volumes rose 279% year on year. That kind of late-year acceleration often carries into the next quarter when buyers, utilities, and trading desks are still adjusting risk books.

Operational timing matters too. Utilities, industrials, and trading desks often increase activity ahead of reporting cycles, auction calendars, and regulatory milestones. Futures let them lock in cost curves and protect budget certainty before emissions data, procurement needs, or policy deadlines force a decision.

The key question is who is driving the flow. Are these mostly compliance hedges, utility risk books, or financial traders expressing a directional view?

How compliance buyers, utilities, and financial traders use EEX carbon futures differently

Compliance buyers EUA futures are usually about obligation management, not price views. They use near-dated contracts to smooth procurement costs, manage surrender obligations, and reduce budget risk when auction exposure and emissions forecasts are uncertain.

Utility hedging carbon cost is usually part of a wider power-market strategy. Utilities and generators often hedge carbon alongside fuel-switching and power-margin exposure, so EUA futures can sit inside clean-dark or clean-spark spread management rather than being a standalone carbon bet.

Financial trading EU ETS activity adds another layer. Financial traders and market makers provide two-sided flow, arbitrage between maturities, and spread trading. That can lift turnover without implying the same compliance need as end users.

A practical example is easy to see. An industrials treasury team may layer quarterly futures to cover expected emissions for the next 6 to 18 months. A prop desk may trade the same curve around policy headlines, auction demand, or volatility signals. The instrument is the same, but the motive is different.

When these user groups all show up at once, rising volume can signal more than hedging. It can also point to a changing view on EU ETS price expectations and volatility.

What rising futures volumes reveal about EU ETS price expectations and volatility

Higher futures volumes often show up when market participants expect a wider range of outcomes for future allowance prices. That can come from policy reforms, supply tightening, macro risk, or cross-market fuel shocks.

Carbon price expectations become more important when the EUA forward curve is sensitive to regulatory timing. The Commission’s 2026 cap adjustments and the MSR’s rule-based supply management make the curve more exposed to policy milestones, which can encourage both hedging and speculative positioning.

EEX’s 2025 data point on the strong rise in secondary-market EUA futures suggests the market was already repricing risk into the back end of the curve. That supports a view of stronger expectation management by corporates and funds, not just more churn.

EU ETS volatility can also improve execution for large buyers. More volume usually means more counterparties, which can help large tickets get done with less market impact. But it can also raise the cost of waiting if the curve starts repricing scarcity before a buyer has covered exposure.

Price discovery in carbon markets becomes actionable only when the market has enough liquidity, open interest, and depth to absorb size efficiently.

The role of liquidity, open interest and market depth in carbon price discovery

Carbon market liquidity is more than traded volume. For B2B users, it also means tighter spreads, deeper order books, better block execution, and lower slippage when hedging multi-quarter exposure.

Open interest EUA futures is a useful signal because it shows unsettled contracts and market interest. EEX highlights open interest as an indicator of positions being carried rather than merely churned intraday, so rising OI alongside turnover usually points to a more durable build in market engagement.

Market depth matters for real hedging programs. In a liquid EUA futures market, utilities can roll hedges efficiently, funds can express calendar spreads, and industrials can build layered procurement programs without moving the market excessively.

That depth also improves discovery. When more participants quote across maturities, futures prices become a better signal of expected scarcity, policy risk, and compliance demand than spot auctions alone.

If Europe’s carbon curve is becoming more liquid and more informative, the next question is what that means for non-EU buyers, investors, and operators watching the market from abroad.

What the surge means for international participants watching Europe’s carbon market

International carbon market participants are increasingly using EEX EUA futures as a reference price for embedded carbon costs in supply chains. That matters where CBAM implications, export pricing, or EU customer requirements create indirect exposure. The Commission says CBAM’s financial adjustment begins from 1 January 2026.

Cross-border carbon risk is not limited to firms with direct EU ETS obligations. International utilities, commodities traders, and industrial groups can use the EU curve as a proxy for transition-policy risk in Europe, even if they do not surrender allowances themselves.

Stronger futures liquidity also makes Europe’s carbon price more bankable for scenario analysis, capital budgeting, and contract negotiation. Procurement, logistics, and sustainability teams can use a deeper curve to test assumptions with more confidence.

The EU ETS remains one of the world’s largest carbon markets and continues to generate major auction revenue, which reinforces its role as a global benchmark for industrial carbon. For VCM participants, that matters too, because compliance-market signals often shape how buyers think about carbon cost, timing, and long-term demand.

The next question is whether this liquidity surge is a temporary quarter-end effect or the start of a more durable, deeper EU carbon market.
