On May 9, the House Energy and Commerce Committee released the third in a series of white papers seeking comments on the renewable fuels standard (RFS). This white paper contains a number of questions seeking to evaluate whether the RFS has impacted greenhouse gas emissions and whether the standard has any unintended environmental consequences on land use. The paper asks whether the RFS has successfully encouraged development of fuels with lower greenhouse gas emissions than traditional petroleum fuels. Responses are due by May 24.
