Tory MP and chair of the House of Commons environmental audit committee Philip Dunne said the government needed to “get on with the transition”.

“It is critical to use everything in our toolbox: from solar farms to onshore wind, tidal to floating offshore wind. The government must double down on efforts and meet its ambitions for renewable energy to power our economy and to electrify heat for buildings.”

The shadow climate change secretary, Ed Miliband, said British businesses were calling out Sunak and the Conservatives on the climate crisis “because they know that this failure is an act of national economic self-sabotage”.

Miliband said the OBR had been “clear that by locking Britain into expensive and unstable fossil fuels, the Tories risk imposing the spiralling costs of future energy shocks and the climate crisis on the British people”.
