ATestR writes "A Times of London article mentions a study published in the journal Atmospheric Chemistry and Physics measured the relative greenhouse gases produced by biofuels produced by two common organic sources, maise (corn) and rapeseed (canola).
From the article: "Rapeseed and maize biodiesels were calculated to produce up to 70 per cent and 50 per cent more greenhouse gases respectively than fossil fuels. The concerns were raised over the levels of emissions of nitrous oxide, which is 296 times more powerful as a greenhouse gas than carbon dioxide. Scientists found that the use of biofuels released twice as much as nitrous oxide as previously realized. The research team found that 3 to 5 per cent of the nitrogen in fertilizer was converted and emitted." The scientists taking the measurement estimated that this is at least 50% greater than similar pollutants produced by fossil fuels.
