The UK was the first country to establish a long-term legally binding framework to cut carbon emissions and since the act was passed many other countries have introduced similar legislation.

However, the Tories said the act forced ministers "to make decisions to meet arbitrary climate targets, even if they make the British people poorer, destroy jobs, and make our economy weaker".

Badenoch said: "We want to leave a cleaner environment for our children, but not by bankrupting the country.

"Climate change is real. But Labour's laws tied us in red tape, loaded us with costs, and did nothing to cut global emissions. Previous Conservative governments tried to make Labour's climate laws work - they don't.

"Under my leadership we will scrap those failed targets. Our priority now is growth, cheaper energy, and protecting the natural landscapes we all love."

However, Miliband said: "This desperate policy from Kemi Badenoch if ever implemented would be an economic disaster and a total betrayal of future generations.

"The Conservatives would now scrap a framework that businesses campaigned for in the first place and has ensured tens of billions of pounds of investment in homegrown British energy since it was passed by a Labour government with Conservative support 17 years ago."

The Liberal Democrats also criticised the announcement.

The party's energy security and net zero spokesperson Pippa Heylings said: "The reality is that investing in renewables is the greatest economic growth opportunity in this century and will protect the planet for future generations."

Meanwhile, Richard Benwell, chief executive of the Wildlife and Countryside Link coalition of environmental groups, said: "The real route to lasting security is in homegrown clean power, not burning more fossil fuels.

"Without binding climate law, ministers will be free to trade away our future - and it is nature and the poorest communities that will pay the price."
