On 15 April 2026, ENVI Members will vote on their negotiation mandate for the market stability reserve (MSR) for the emissions trading system covering buildings, road transport and additional sectors (EU ETS2).The MSR aims to mitigate the risk of supply and demand imbalances associated with the start of the EU ETS2 and to make it more resistant to market shocks. The Commission proposal amends Decision (EU) 2015/1814 to enhance predictability of initial price levels, without affecting the overall design of the MSR. The MEPs have tabled 111 amendments to the Commission proposal and have negotiated one compromise amendment that will be put to a vote. The compromise amendment aims to introduce a gradual invalidation of unused allowances in the reserve and to shorten the reaction time for releasing allowances to the market. It also calls on the Commission to carry out an impact assessment on the environmental, economic and distributional effects of remaining allowances in the reserve, to ensure the system supports both climate objectives and a stable market functioning. The ENVI vote will be followed by a plenary vote in April and by negotiations with the Council to find an agreement.Source : © European Union, 2026 - EP
