EU carbon price deal aims to calm ETS2 launch before 2028 heating and road fuel pricing

EU negotiators have reached a provisional deal on rules for the ETS2 market stability reserve, the mechanism designed to prevent wild price swings when carbon pricing hits buildings and road transport in 2028. The agreement doubles the number of allowances released if the carbon price exceeds EUR 45 per tonne of CO2, and extends the reserve beyond 2030. The goal is to keep the system credible without triggering a cost of living backlash. The political test is whether member states use ETS2 auction revenues for renovation, heat pumps, and cleaner transport rather than treating them as general budget relief. If national governments underinvest in alternatives, a steadier carbon price may not be enough to secure public trust. The deal still needs formal approval from both the Council and Parliament.
