EU carbon study celebrates a cap that Brussels is already proposing to loosen
The ETS has cut industrial emissions nearly in half in three years, but the Commission's move to slow allowance retirement challenges the supply trajectory behind that result.
The European Commission proposed on Thursday (2026-07-17) to slow the rate at which EU carbon allowances are retired, reducing the linear reduction factor to 3.7%, as part of an effort to lower compliance costs for European industry.4 The proposal emerged one day after a study declared the EU ETS had already reduced industrial emissions by almost half in three years, with current policies sufficient to deliver net zero by 2050.3 ICE EUA Dec-rolling last traded at €78.40 per tonne at Friday's (2026-07-17) close.
The study's findings are not in dispute. A near-50% cut in industrial emissions in three years is a real outcome, delivered under the existing reduction trajectory. The problem for those pricing EUA on that number is that the Commission announced the next day its intention to alter the mechanism that produced it.3,4
Carbon Market Watch put a number on this in May (2026-05-11) when a similar deceleration proposal was circulating. A slower reduction pace, the NGO calculated, could add allowances to the EU ETS equivalent to three additional years of issuance under the current path.1 The Commission has since moved to a specific figure (3.7%), though the full supply impact relative to the current trajectory is not yet quantified in available detail. The NGO's May analysis at least establishes the order of magnitude: this is not a marginal revision.4,1
The consensus on ICE EUA Dec-rolling is mildly bullish, but the supply implication of Thursday's (2026-07-17) proposal may be receiving less attention than its timing warrants. The study published Wednesday (2026-07-16) is backward-looking — it records what a tight cap achieved over three years. The Commission's proposal is forward-looking — it adjusts the cap from here. One describes past performance; the other changes future supply.3,4
The study's net-zero projection is calibrated to existing reduction rates. A looser cap means more allowances available over the medium term, lower average clearing prices, and a slower convergence toward scarcity. For ICE EUA Dec-rolling, the supply arithmetic of 3.7% versus the incumbent trajectory is the operative variable — not the historical emissions record for 2023-2025.4,1
UK Carbon Allowances last priced at £57.77 per tonne at Friday's (2026-07-17) close. The UK ETS operates independently but follows EU ETS design decisions closely; any sustained softening in EU allowance supply assumptions tends to affect the cross-market price relationship. The Commission's proposal does not alter the UK cap directly, but it shifts the reference point UK participants use when calibrating their own market's trajectory.4
A further complication comes from a June (2026-06-11) study indicating the EU ETS would tighten sharply without integration of carbon removal mechanisms.2 If the Commission is simultaneously slowing allowance retirement and leaving the removal question unresolved, the supply position is looser on both counts — and the Wednesday (2026-07-16) success study's trajectory assumed neither condition.
The proposal's survival through parliamentary and member-state scrutiny is the first real test. Climate-aligned governments in the EU have resisted previous dilution attempts; if the proposal is narrowed or rejected, the supply addition Carbon Market Watch modelled in May (2026-05-11) does not materialise and EUA returns to the tighter supply profile the emissions study implies.1,4 If it passes intact, the study becomes a record of what the EU ETS achieved under conditions Brussels has since decided to ease.
