Lord Lawson is challenging the environmental orthodoxy
In a HARDtalk interview screened on December 13, Zeinab Badawi spoke to the former Chancellor of the Exchequer, Lord Lawson of Blaby.
The Meeting of Parties to the Kyoto Protocol in Montreal has been hailed as a major step forward in the fight against global warming.
Industrial nations other than the United States and Australia agreed to negotiate deeper cuts in their emissions of fossil fuels.
In Britain the new leader of the Conservative Party has declared the environment to be a priority and thinks there should be legally binding international agreements on emissions.
Nigel Lawson, Chancellor of the Exchequer to Margaret Thatcher, disagrees.
He thinks the Kyoto agreement is wrong and the International Panel on Climate Change should be shut down.
He explains why to Zeinab Badawi.
