European carbon market collapse prompts calls for reform amid industrial volatility

Carbon allowances across the European carbon market tumbled to levels not seen since August 2025, rattling utilities and energy‑intensive manufacturers and prompting renewed debate about the future shape of the EU Emissions Trading System (ETS).

Trading in permits , the central mechanism by which the ETS caps and reduces greenhouse gas emissions for power, industry and aviation , weakened sharply after German Chancellor Friedrich Merz signalled last month that the bloc should consider delaying or reworking elements of the market. His remarks were reflected in discussions among EU leaders at a summit in Belgium, and investors responded by marking down shares of firms exposed to the cost of compliance.

The downturn comes against a mixed backdrop for Europe’s decarbonisation agenda. Data compiled in the 2025 Carbon Market Report show that emissions from the power and industrial sectors have fallen substantially versus 2005 levels, with a roughly 50% reduction to date and a projected 62% decline by 2030. The power sector in particular saw an 11% year‑on‑year drop in 2024 as renewables expanded and coal generation ceded ground to gas and wind and solar capacity, according to reporting in Brussels. Those structural shifts have reduced the immediate demand for allowances even as policy tightens the supply through annual cap cuts.

At the same time policymakers have been rolling out complementary instruments designed to protect European industry from overseas competition. The EU implemented the Carbon Border Adjustment Mechanism (CBAM) on 1 January 2026, imposing an emissions‑related charge on imports of carbon‑intensive goods such as steel, cement, aluminium and fertilisers. The measure targets a narrow slice of trade initially , some 303 product categories representing roughly 3% of EU imports , but it is expected to broaden over time, potentially covering an additional €55 billion of goods. Industry groups, however, have warned about implementation hurdles, fraud risks and administrative complexity, and some executives remain sceptical that CBAM will fully prevent carbon leakage or secure competitiveness on its own.

Industry reactions to the recent permit price slump have been divided. Some business leaders and trade associations seized the moment to urge regulatory reform, arguing that price volatility and the interaction between the ETS and new measures such as CBAM require clearer design to give firms predictable investment signals. Others cautioned against rushed intervention in a market that, on longer horizons, is meant to tighten supply and raise the cost of emitting carbon to drive decarbonisation.

Chancellor Merz has framed his intervention in competitiveness terms, advocating broader deregulation and flexibility in Europe’s industrial transition. Speaking at industry forums and bilateral meetings, he has called for an assessment of whether the current market architecture remains the right instrument to balance emissions reductions with industrial resilience. His stance resonates with political concerns in several member states about energy costs and the pace of technological change, particularly in sectors undergoing rapid electrification or process transformation.

Market participants and policy analysts say the near‑term fall in allowance prices highlights the ETS’s exposure to shifts in political rhetoric and macroeconomic conditions, even as the longer‑term trajectory of the system, annual cap declines and tighter allocation, remains aimed at deep emissions cuts. According to commentators familiar with the market, investor sentiment could stabilise if policymakers reaffirm the ETS’s commitment to declining caps and if CBAM implementation reduces competitive distortions for domestic producers.

For companies planning capital‑intensive decarbonisation projects, the episode underlines two practical imperatives: maintain flexibility in investment plans to manage permit‑price volatility and press for regulatory clarity that aligns carbon pricing, border adjustments and industrial support measures. As Europe’s policy toolkit evolves, firms active in electrification, materials substitution and energy efficiency will need to navigate a regulatory landscape where short‑term market moves can be abrupt but long‑term policy targets continue to push toward lower emissions.

The policy tug‑of‑war also presents risks for policymakers. Easing the ETS prematurely or introducing ad hoc market fixes could undermine credibility and slow emissions reductions, while failing to address legitimate competitiveness concerns may provoke political backlash and delay industrial transformation. The challenge for Brussels and member states will be to reconcile those competing pressures: sustain a credible carbon price path that incentivises low‑carbon investment while deploying complementary measures that shield exposed sectors during the transition.
