Clinton campaign studying alternative to U.S. ethanol mandate

By Valerie Volcovici and Rory Carroll, Reuters.

Democratic U.S. presidential candidate Hillary Clinton's campaign has solicited advice from California regulators on how to revamp a federal regulation requiring biofuels like corn-based ethanol be blended into the nation's gasoline supply, according to campaign and state officials.

The move is the clearest sign yet that, if elected, Clinton would seek to adjust the regulation, called the Renewable Fuel Standard, possibly hurting her chances in corn-growing states like Iowa where she faces a tough battle against Republican rival Donald Trump in the Nov. 8 election.

The Renewable Fuel Standard, created by Congress in 2005, mandates that transportation fuel sold in the United States contain a minimum volume of renewable fuels.
