Frequent Questions

Does the ratio of feedstock quantity used to volume of renewable fuel produced have any significance in the RFS program? Would it impact the qualification of a renewable fuel's pathway or the equivalence value of the fuel?

The amount of feedstock used to produce a biofuel is one of many factors that EPA takes into consideration in its assessment of the lifecycle GHG performance of a particular fuel pathway. However, once EPA establishes the lifecycle performance of the fuel pathway the amount of feedstock needed at a particular facility is not used for lifecycle performance verification. It is however, one piece of information that EPA can look at for assessing the reasonableness of reported fuel volumes produced and RINs generated. Equivalence values in the program are used to determine the number of RINs that are generated for each gallon of fuel produced. Equivalence values are based on the energy content of the fuel produced and are not impacted by the amount of feedstock needed to produce the fuel.
