Does the biodiesel tax credit change the advanced biofuels landscape?

The RFS for 2013 is expected to require a minimum blending of 1.28 billion gallons of biodiesel and 2.75 billion gallons of all advanced biofuels. The difference between the minimum biodiesel requirement and the minimum total requirement is referred to as undifferentiated biofuel. That requirement can be met by Brazilian ethanol, biodiesel, or cellulosic ethanol. Since cellulosic ethanol is not available in any substantial quantities, the requirement will be met by either Brazilian ethanol or domestic biodiesel.
