Renewable Fuels Mandate

One year after in-state production has reached 350 million gallons of cellulosic ethanol and sustained this volume for three months, all gasoline sold in Pennsylvania must contain at least 10% cellulosic ethanol. All diesel fuel sold in Pennsylvania must contain at least 2% biodiesel (B2) one year after in-state production of biodiesel reaches 40 million gallons. The mandated biodiesel blend level will continue to increase according to the following schedule:

  • 5% biodiesel (B5) one year after in-state production of biodiesel reaches and sustains 100 million gallons for three months;
  • 10% biodiesel (B10) one year after in-state production of biodiesel reaches and sustains 200 million gallons for three months; and
  • 20% biodiesel (B20) one year after in-state production of biodiesel reaches and sustains 400 million gallons for three months.
Biodiesel blends must comply with ASTM specifications. All biodiesel retailers in Pennsylvania must register with the Pennsylvania Department of Agriculture each year. Additional compliance and blending standards, in-state registration requirements, and certification and enforcement guidelines apply.
