Minnesota was the first state to require the use of biodiesel, and currently has a 20 percent biodiesel blend (B20) standard during the summer months.

B20 in Minnesota

As of May 1, 2018, all No. 2 diesel fuel sold for use in combustion engines must contain at least 20 percent biodiesel until September 30, 2018.

  • Starting in 2019, all No. 2 diesel fuel must contain at least 20 percent biodiesel between April 1 and September 30.
  • From October 1 to March 31, No. 2 diesel must contain at least 5 percent biodiesel.
  • No. 1 diesel is exempt from the biodiesel requirement year-round.

The Minnesota B20 Handling Guide (PDF) gives an overview of Minnesota’s biodiesel standard.


Minnesota has three biodiesel plants with a combined production capacity of approximately 85.5 million gallons per year:

  • REG (Albert Lea) – 42 million gallons
  • Minnesota Soybean Processors (Brewster) – 40.5 million gallons
  • EverCat Fuels (Isanti) – 3 million gallons

“Minnesota has been and continues to be a renewable fuels leader,” said Minnesota Agriculture Commissioner Dave Frederickson. “The biodiesel industry has not only continued to grow but has also continued to improve in every way. It cleans up our air quality, supports economic development in greater Minnesota, and adds value to our agriculture sector. It’s a vital and innovative industry that we must continue to support.”


In 2002, the state legislature passed a law that required diesel fuel sold in Minnesota contain at least 2 percent biodiesel (B2) (Minnesota Statutes 239.77). The law went into effect on September 29, 2005. The mandate increased to 5 percent (B5) on May 1, 2009 and 10 percent (B10) on July 1, 2014.

On July 25, 2017, the commissioners of the Departments of Agriculture, Commerce, and the Minnesota Pollution Control Agency determined that there was sufficient biodiesel supply, adequate blending infrastructure, and federal standards in place to require a higher biodiesel content. On May 1, 2018, the biodiesel mandate increased to 20 percent (B20).
