The UK must cooperate with the European Union (EU) on energy and climate change following Brexit or it risks complicating its own emission reduction plans, according to a think tank.

In a new report, the Green Alliance outlined a “Paris co-operation track” for the UK and the EU to follow.

The think tank wants to see the UK remain part of the European internal energy market for electricity and gas.

It also suggests the UK should remain part of regulatory bodies such as the Agency for the Co-operation of Energy Regulators and the Energy

Transmission System Operators for gas and electricity, in order to give Britain a voice over regulations.

European court will be key

The report added: “The future role of the European Court of Justice (ECJ) is also a vital consideration. Achieving a positive outcome would be hindered by a hard negotiating position on the ECJ.

“The UK’s strong stance on the ECJ is a major stumbling block for any agreement, because it is so heavily involved in governing the shared energy and climate rules.

“An EU-UK Association Agreement, similar to the EU’s one with the Ukraine, would be one way to reconcile existing political stances with the desired outcomes.”
