This briefing “UK-EU Relations: Energy and Climate” published by the United Kingdom House of Commons Library provides background on energy and climate provisions in the UKEU Trade and Cooperation Agreement (TCA), developments in UK-EU cooperation on energy and climate since the UK left the EU, and the main outcomes of the May 2025 UK-EU summit.
The UK hosted a UK-EU Summit in May 2025 where a new Common Understanding between both parties was reached. The Common Understanding included commitments to work towards strengthened cooperation across a range of policy areas, including energy and climate.
The briefing lays down requirements on competitive energy markets and arrangements for the trading of energy through gas and electricity inter-connectors. It also establishes a framework for cooperation on security of supply and includes provisions to support developing renewable energy. It further includes provisions that relate to maintaining each party’s respective level of ambition with regard to climate and environmental protection, implementing carbon pricing mechanisms, and upholding the Paris Agreement. Since the UK and EU agreed to the TCA, they have progressed cooperation on energy through the Specialised Committee for Energy.
