WASHINGTON, DC – PA U.S. Sen. Pat Toomey has introduced legislation to end the corn ethanol mandate in the Renewable Fuel Standard. The mandate requires annual increases in the amount of ethanol that must be blended into the total volume of gasoline refined and consumed in the United States. Toomey said forcing Americans to buy billions of gallons of corn ethanol is a terrible policy. He added that the Renewable Fuel Standard drives up the cost of gas and food, harms the environment, and damages engines. Supporters of the bipartisan bill say corn ethanol achieves little to no reductions in greenhouse gas emissions over regular oil and poses other environmental risks. About 40% of the U.S. corn crop is used to produce ethanol, artificially inflating food and feed prices.
