Biofuels - A Dumb 1990 Idea That Is Getting Dumber
A report examining the impact of biofuels on greenhouse gas emissions during the 21st century has found that carbon loss stemming from the displacement of food crops and pastures for biofuels crops may be twice as much as the CO2 emissions from land dedicated to biofuels production. The Science Express study also predicts that increased fertilizer use for biofuels production will cause nitrous oxide emissions (N2O) to become more important than carbon losses, in terms of warming potential, by the end of the century. Using a global modeling system that links economic and biogeochemistry data, the researchers examined the effects of direct and indirect land-use on greenhouse gas emissions as the production of biofuels increases over this century. read more
