Emission controls are high on the agenda of many fleet managers, while some are also having to get their heads around carbon trading. Amid all the environmental panic, it's interesting to look at the views of Scandinavian "sceptical environmentalist" Bjorn Lomborg. He is not impressed with the European Union's commitment to cut its emissions by 20% by 2020. Interestingly, Lomborg points out that all this will achieve is postponing global warming by about two years at the end of the century. In effect, he says, Europe will spend EUR60 billion (USD95 billion) to slow the temperature rise by two years, meaning we'll reach 2100's predicted average by 2102. Surely, he argues, there are more effective uses for that money. Makes you think, doesn't it?
