The Iowa Senate passed a bill this week to create a biodiesel tax credit for retailers, as well as include biodiesel in the 25 percent of petroleum displacement the state would require by 2020. The amended bill now moves back to the state House, which passed an earlier version by a vote of 92-7. National Biodiesel Board officials are hoping other states might follow Iowa’s lead. “Iowa is demonstrating bold leadership by promoting renewable biodiesel and ethanol,” said Joe Jobe, National Biodiesel Board CEO. “It is positioning itself as a significant energy exporter and could become the Texas of the Midwest.”
