On April 4, 2017, the Iowa Biodiesel Board (IBB) announced that the Iowa Department of Revenue’s 2016 Retailers Fuel Gallons Annual Report demonstrated that more than half of Iowa’s fuel retailers carried biodiesel blends in 2016.  In 2016, 344.8 million gallons of on-road biodiesel blends were sold, which accounts for 54.7 percent of total on-road diesel fuel sales.  The report also showed that twice as many gallons of 11 - 20 percent biodiesel (B11-B20) were sold compared to lower blends.  IBB credits the growth in the use of higher biodiesel blends to Iowa’s proactive state policies, which are working as intended to increase production and consumption.  Due to the instability at the federal level, Grant Kimberley, the IBB executive director, stated that Iowa’s biofuel producers need state tax credits to stay in place now more than ever to remain competitive.
