EPA Proposes Biofuel Mandate

The Environmental Protection Agency proposed a cellulosic biofuel mandate that it said complies with a court ruling that overturned its previous methodology for the mandate.

Under the proposal, fuel refiners would have to blend 14 million gallons of cellulosic biofuel into diesel and gasoline this year.

An appeals court threw out EPA’s 2012 mandate of 500 million gallons on Jan. 25, saying the methodology it used was overly optimistic about the amount of the fuel that is produced each year.

Cellulosic biofuel is made from wood biomass materials and can be used as diesel or gasoline.
