It was possible to make such changes in a "cheap" way, he told the BBC.

 

But Labour said there had been a "decline in investment in green energy" under the coalition¹ government. 

 

The long-awaited UN report on how to curb² climate change said the world must rapidly move away from carbon-intensive fuels. 

 

There must be a "massive shift" to renewable energy sources such as wind and solar, it argued, saying natural gas was an important stage in a movement away from oil and coal.

"We need a large-scale change to our global energy system if we are to limit the effects of climate change. The longer we leave it, the more difficult and costly⁵ it will be."
