MADISON — Transportation is responsible for a larger share of greenhouse gas emissions than any other sector of the U.S. economy, making biofuels a promising strategy to mitigate human-driven climate change. The U.S. Renewable Fuel Standard, created by 2007 legislation, mandates that such fuels partially replace petroleum-based ones. So far, however, the mandate has been nearly entirely fulfilled by corn ethanol, a fuel that may be worse for the climate than the gasoline it replaces.
