The U.S. government spending bill signed into law in late December 2019 included several provisions related to federal energy programs. Among these provisions was the reinstatement of a $1.00 per gallon biodiesel mixture credit, commonly referred to as the biodiesel tax credit (BTC). The BTC applies to both biodiesel and renewable diesel (referred to as biomass-based diesel) through 2022. The credit was also retroactively applied to 2018 and 2019.
