'Unburnable' Carbon

Duration:
18 minutes
First broadcast:
Thursday 26 September 2013

As the world awaits the release of the latest UN reports on climate change, what impact will its forthcoming forecasts have on energy companies? Are coal and oil companies being massively overvalued by financial markets, because the oil and coal reserves that they own will never be dug up and burnt due to fears about global warming. We talk to environmentalist and businessman Jeremy Leggett, who claims that the fossil fuel deposits boasted by these companies are worthless, because to exploit them would cause catastrophic climate change. We also ask an equity analyst from the City whether it is true that investors are failing to take account of this 'unburnable carbon'.

Also in the programme, we speak to John Whelan, the world champion of reversible ploughing about the future of farming.
