It’s been a tough week for corn ethanol producers and supporters of the federal Renewable Fuel Standard (RFS).

Looking back over the last 10 years, the RFS and its resulting promotion of corn ethanol as a leading oxygenate supplement to conventional transportation fuels did not meet intended environmental goals. Corn ethanol’s environmental record has failed to meet expectations across a number of metrics that include air pollutants, water contamination, and soil erosion. Corn ethanol has resulted in a number of less favorable environmental outcomes when compared to a scenario in which the traditional transportation fuel market had been left unchanged.
