A recent study from the Proceedings of the National Academy of Sciences finds that corn ethanol is a larger contributor to global warming than straight gasoline.
Tyler Lark, a scientist at the University of Wisconsin and lead author of the study, tells Brownfield the results show that biofuels are not a climate solution. “Corn ethanol, which was initially intended to reduce climate warming, greenhouse gas emissions, likely increases them relative to gasoline while also contributing to other increases in soil erosion, nutrient pollution and loss of habitat.”
The research studied the environmental impacts of the Renewable Fuels Standard after it was implemented in 2007.
