Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent assessment he made of the potential impact of the Energy Charter Treaty's sunset clause on fossil fuel assets on the financial risk of legal challenges to the UK.

The UK withdrew from the Energy Charter Treaty on 27 April 2025. Ten other Energy Charter Treaty Contracting Parties have withdrawn, or are withdrawing from the Energy Charter Treaty.

The UK Government is committed to delivering its Growth and Clean Energy Missions agendas and to working multilaterally to achieve this, such as at the OECD and the UN.
