Climate change and health costs of air emissions from biofuels and gasoline

source: Proceedings of the National Academy of Sciences, vol. 106,no.6 (Feb.2009)
"A new study from the University of Minnesota finds that biofuel made from corn can be as harmful to the environment as gasoline, and that the combined costs to climate-change and health exceed that of gas. The study notes that the environmental impacts of energy use can impose large costs on society. It quantifies and monetizes the life-cycle climate-change and health effects of greenhouse gas (GHG) and fine particulate matter (PM2.5) emissions from gasoline, corn ethanol, and cellulosic ethanol."
