What happened
EU ambassadors endorsed changes to the EU Emissions Trading System (ETS) that would retain excess carbon allowances in its Market Stability Reserve rather than permanently removing them.
The reserve manages permit supply in the ETS, under which major power and industrial operators must hold allowances for their carbon dioxide emissions. At present, allowances beyond the applicable reserve level can be cancelled when the reserve exceeds 400 million permits.
Under the member-state position, surplus allowances would remain in the reserve through 2030. They could be used as an additional supply source if carbon prices rise rapidly. The existing price-control mechanism allows 75 million allowances to be released when the ETS price more than doubles.
From 2031, cancellations would begin again when the reserve holds more than 800 million allowances. That trigger level would fall each year thereafter.
Why it matters
The proposal would give EU policymakers more room to respond to carbon-price volatility. This matters to businesses covered by the ETS, including electricity generators and energy-intensive industrial facilities, because permit costs affect operating costs and planning.
ETS charges account for roughly 11% of industrial electricity bills across the EU on average, although the effect differs between national power systems. Countries relying more heavily on fossil fuels face a greater exposure than those with substantial nuclear and renewable electricity generation.
Poland, Italy and other governments have pushed for measures to reduce carbon-related energy-cost pressure amid higher fuel prices linked to the Iran conflict. The change could affect expectations for future allowance availability, alongside companies’ compliance and risk-management decisions.
Background
The European Commission put forward the amendments in April in response to concerns about energy affordability. The ETS is the EU’s principal carbon-pricing system for power generation and energy-intensive industry. Its allowance market is intended to make emissions more costly while supporting investment in lower-carbon options.
What's next
The member states’ agreement establishes their position for talks with the European Parliament. The final rules will determine whether and how the proposed reserve arrangements are adopted. If agreed in their current form, the no-cancellation period would run to 2030, with the revised cancellation mechanism starting in 2031.
