Sweden Pushes 4.4% ETS Cap Cut as EU Weighs Reform That Could Sink Carbon 13%
Stockholm's call for a tighter emissions cap collides with a Commission adjustment that one analyst says would cut EU carbon prices roughly 13% over two years.
Sweden is urging the European Union to tighten its emissions trading system by cutting the carbon cap 4.4% to accelerate the bloc's green transition, according to Montel.2 The push lands as EU carbon trades near €78.80, based on the KRBN carbon proxy, and as Brussels moves in the opposite direction on a separate reform.2
The timing is awkward. A senior analyst at Veyt said on Wednesday (2026-05-20) that an ETS adjustment being weighed by the European Commission could cut EU carbon prices by about 13% over the next two years.1 Stockholm wants a scarcer allowance supply; the Commission is considering a change that would loosen it. Those two impulses cannot both win.1
The mechanism matters for anyone holding carbon. Under the current rules, when the total number of allowances in circulation exceeds 833m tonnes, auction volumes are reduced by 24% and pulled into the market stability reserve.1 That reserve has kept the EUA market tight through the demand slump of recent years. Any change to how it absorbs surplus supply feeds directly into forward carbon curves.1
If the Commission proceeds with the adjustment Veyt flagged on Wednesday (2026-05-20), the downward pressure would work against exactly the scarcity Sweden is asking for.1,2
Sweden is not the only member state lobbying. Italy urged the EU on Thursday (2026-04-23) to scrap a planned revision to ETS benchmarks that govern free carbon allowances to industry, warning the move would raise compliance costs for energy-intensive manufacturers and weaken European industrial competitiveness.7 Rome wants less pressure on industry; Stockholm wants more ambition on the cap. The Commission sits between them.7
An Italian study released on Thursday (2026-05-21) added a further complication, arguing the EU needs more tools than the ETS to finance Europe's green buildout and that the system's benchmarks may be structurally biased.2 The message from Rome is that leaning on carbon prices alone will not deliver the investment the transition needs.2
There is a wider retreat underway. The Commission has already moved to simplify its carbon border adjustment mechanism, saying that excluding all shipments under 50 tonnes means 90% of firms originally obliged to participate no longer have to, a change it says still leaves 99% of targeted emissions covered.5 The Economist described the broader effort as a humbling of green Europe, with member states pressing for standardised climate-plan and risk-accounting rules to apply only to large firms.5 Against that current, a tighter cap is a hard sell.
Sweden's negotiating position is complicated by its own recent conduct. Swedish energy minister Ebba Busch paused all interconnector projects to other EU states in the week of 2026-05-04, including a 1 GW link, according to a source who spoke to Montel.6 Stockholm has continued talks with the Commission over new power grid revenue rules, particularly those covering new capacity and energy storage.6 A member state asking Brussels for more climate ambition while freezing cross-border grid links invites the obvious rejoinder.
The political backdrop is not helping carbon bulls. The European Council on Foreign Relations noted on 2026-05-19 that many governments face a growing domestic greenlash and fears over the costs of climate action, even as most remain formally committed to the transition.3 That pressure pushes the Commission toward the softening reforms Sweden opposes, not the tightening it wants.3
For carbon traders, the decisive question is whether the Commission formalises the adjustment Veyt described, and on what timeline.1 A firm proposal to alter the market stability reserve's intake would move the EUA curve more than Sweden's cap ambition, which needs unanimity it does not obviously command. Corporate demand offers a thin floor: Uniper has committed to phasing out commercial coal-fired power and cutting Scope 1 and 2 emissions at least 55% against a 2019 base year, the kind of compliance buying that underpins allowance demand regardless of policy noise.4
The near-term risk is asymmetric. Sweden's proposal faces a long legislative road and hostile capitals; the Commission's loosening reform is already on the table and carries a quantified downside for prices.1 Watch the Commission's next ETS text, and whether Italy's benchmark objection gains signatories.7
