The network for young environmentalists
The following article was published in todays' Sueddeutsche Zeitung
(Wissen). To sum it up: According to Paul Crutzen (Max-Planck-Institute for Chemistry) agricultural fertilizers (especially nitrogen) used for corn and canola cultivation in order to produce biofuels (biodiesel and bioethanol) cause more damage to the climate than fossil fuels. Canola fuel has a 1.7, corn a 1.5 factor to climate damage (in comparison to the savings of CO2 from fossil fuels). According to David Reay of Edinburgh University the modelled outcome of the United States effort to increase their biofuel consumption by 7 times (2022) would raise the overall emission by 6 % if Crutzens' model is right.
