The costs of tackling climate change have become highly politicised in recent years.

The CCC estimates most of the expense will be borne by the private sector and calculates the savings from moving to more efficient technologies should outweigh costs by the early 2040s.

“We are crystal clear in this analysis, in this carbon budget, for the first time we start to see the economy making savings from this investment, and they make savings over and above what we would do if we stay dependent on fossil fuels,” Ms Pinchbeck told BBC News.

This should improve energy security and filter down to lower bills in the long term, the CCC argues, provided the government acts to make electricity cheaper.

It advises removing policy costs – funding for social and environmental schemes – from electricity bills. That would cut them by about 19% based on expected 2025 prices, the CCC says, making it more cost-effective for people to switch to electric vehicles or heat pumps.

These costs could instead sit on gas bills or general taxation.

“Regardless of what you think about climate change, what we are laying out today is a massive industrial revolution,” said Ms Pinchbeck.

“It will save the economy money by 2040, it saves people money on their energy bills, it saves people money on their driving costs, but all of that is underpinned by a cheaper electricity price.”
