(NAFB.com) – Clean Fuels Alliance America asked the D.C. Circuit Court of Appeals to review the EPA’s final Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles – Phase 3. In the final rule, the Environmental Protection Agency evaluated a range of alternative fuel and engine configurations for 2027-2032 heavy-duty vehicles. However, the agency specifically declined to consider biodiesel and renewable diesel in combination with existing engines that are already widely available. “EPA put its thumb on the scale to favor electric and hybrid vehicles that are not guaranteed to be widely available in the timeframe addressed by the rule,” says Kurt Kovarik, vice president of federal affairs for Clean Fuels Alliance America. “The agency refused to consider the increasing availability of biodiesel and renewable diesel as an achievable, affordable technology for meeting the goals of heavy-duty truck rules by 2032.” The Alliance represents the entire biodiesel, renewable diesel, and sustainable aviation fuel industry supply chains.
