Biofuels could increase global warming with laughing gas, says Nobel prize-winning chemist Discussion at PhysOrgForum
Growing and burning many biofuel crops may actually raise, rather than lower, greenhouse gas emissions. That’s the conclusion of a new study led by Nobel prize-winning chemist Paul Crutzen, best known for his work on the ozone layer.

He and his colleagues have calculated that growing some of the most commonly used biofuel crops releases around twice the amount of the potent greenhouse gas nitrous oxide (N2O, also known as ‘laughing gas’) than previously thought – wiping out any benefits from not using fossil fuels and, worse, probably contributing to global warming.

‘The significance of it is that the supposed benefits of biofuels are even more disputable than had been thought hitherto,’ Keith Smith, a co-author on the paper and atmospheric scientist from the University of Edinburgh, told Chemistry World magazine. ‘What we are saying is that [growing many biofuels] is probably of no benefit and in fact is actually making the climate issue worse.’
