CCC

The switch towards greener energy has already halved the UK's annual greenhouse gas emissions since 1990 - but the CCC has previously said further reductions will be difficult without lifestyle changes.

While the UK has already cut its emissions by more than 50% since 1990, the CCC says it should extend this to 81% by 2035, which would make a "credible contribution" to the international goal of limiting global warming to 1.5C.

A spokesperson said the government would carefully consider the CCC’s advice.

“All the core technologies have got cheaper, and they keep getting cheaper, and that's what gives us more and more confidence that we'll be able to achieve this very ambitious level of emissions reductions,” Nigel Topping, member of the CCC, told BBC News Climate Editor Justin Rowlatt.

The CCC calls for the UK to commit its fair share of money in line with its leadership ambitions.
