(NAFB.com) – The foundation is strong for expanding biodiesel, renewable diesel, and sustainable aviation fuel in the U.S. However, to build on the growth of recent years, producers and stakeholders have to remain united. That’s according to Clean Fuels Alliance America CEO Donnell Rehagen, who shared that message with attendees at the Clean Fuels Conference in Orlando, Florida. Clean fuel producers persevered through a year that saw slower production amidst unsettled regulations, including questions about the 45Z tax credits and the possibility of Renewable Fuel Standard exemptions for small refineries. “Positive results from last year showed what happens when we set aside some differences and work together,” Rehagen said. “When biodiesel and renewable diesel producers joined forces with oil and gas refiners who’ve invested in our space, and farmers, when we aligned on RVO goals, we saw something powerful emerge.”
