He is concerned that the United Nations-led consensus that a climate treaty must focus on cuts in greenhouse gas emissions from rich countries is mistaken.
“It’s a costly way to achieve very little,” he said.
Instead, Mr Lomborg argues, there are cheaper ways of halting temperature rises.
These include tackling sources of climate change other than carbon dioxide, such as methane and soot; investing in new technologies; adapting to the effects of climate change; planting more forests; and weighing up whether emissions cuts are cheaper to do now or later.
