Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to the UK-EU Summit - Common Understanding on linking the Emission Trading Systems of the European Union and the United Kingdom, of December 2025, what assessment he has made of the potential implications for his policies of the proposed reform of the EU Emissions Trading System.

The UK and EU agreed to work towards linking their respective emissions trading schemes at the May 2025 Summit and linking negotiations to that end are underway.

The EU Emissions Trading System is undergoing review currently and proposals emanating from that review are expected to be issued this summer.
