Safeguarding Against Price Surges
EU countries have agreed to update a key financial mechanism to prevent sudden spikes in carbon prices as the bloc prepares to introduce a new carbon tax on cars, vans, and buildings. The system, part of the European Union’s emissions trading scheme (ETS2), is set to start in 2028. Households and businesses using fossil fuels for heating and transport are expected to face higher bills once the scheme is fully operational, prompting debate over its social impact.
While Slovakia and the Czech Republic have called for a delay until at least 2030, Sweden, Denmark, Finland, the Netherlands, and Luxembourg oppose any postponement, warning that weakening or delaying ETS2 could undermine EU climate policy and create uncertainty for businesses and households.
How the Market Stability Reserve Will Work
Central to this plan is the Market Stability Reserve, a long-term tool that balances supply and demand in the carbon market and acts as a buffer against price shocks. The mechanism currently holds 600 million allowances — enough to cover roughly ten years of emission reductions — which can be released if prices spike.
Under the revised rules, releases will increase by 20 million allowances each time and can occur twice a year, allowing up to 80 million allowances to enter the market to smooth price fluctuations. ETS2, extended to cover road transport and buildings, aims to reduce emissions in these sectors by 42% by 2030 compared with 2005 levels. The rollout was originally planned for 2027 but delayed over social concerns.
Balancing Climate Action and Social Impact
Officials say the changes signal the EU’s commitment to a stable, predictable carbon market while protecting citizens from sudden price hikes. The European Investment Bank recently added €3 billion to support households facing rising energy costs, reflecting pressure from lawmakers to safeguard vulnerable groups.
The Council’s agreement now moves to the European Parliament, which must approve the final rules before ETS2 launches in 2028. The challenge for the EU will be ensuring the carbon market drives emissions reductions while maintaining affordability and confidence for consumers and investors.
