In the first of a series of video interviews, Britain’s leading green commentator, George Monbiot, charges the UN’s leading climate change official with lacking ambition for a global emissions deal, and takes him to task over expensive carbon offset schemes and his support for the US president, George Bush. In the coming weeks, Monbiot takes on the bosses of Shell and the International Energy Agency and more. (Note: This film includes stock footage from Greenpeace)
