Renewable Fuel Standard (RFS):

The Environmental Protection Agency's delays in setting the 2021 Renewable Fuel Standard obligations create uncertainty for the biodiesel and renewable diesel industry. While the agency provided compliance flexibility to oil refineries, it created addtional uncertainty for biofuel producers by indicating to reporters that it would retroactively slash RFS volumes for both 2020 and 2021.

Please contact your Representative and Senators and update them on the situation through this form. As the 117th Congress considers legislative options to address environmental and economic issues, this is an opportunity to let lawmakers know that support for the RFS helps biodiesel and renewable diesel producers.


As our members and industry supporters communicate with Washington policy makers, the media, and the public, NBB provides the resources to the right and works with them to amplify these points:

  • EPA knows that RFS deadlines are important to all program stakeholders. Biodiesel and renewable diesel producers particularly rely on market signals from annual rules.
  • The missed deadlines create additional uncertainty for biodiesel and renewable diesel producers, who have set goals for continued growth through 2030.
  • EPA destroyed demand for hundreds of millions of gallons of biodiesel over the past several years by abusing small refinery exemptions. EPA has many options to repair the damage to the biodiesel industry and is required to do so.
  • Each small refinery exemption can eliminate demand for an entire biodiesel facility’s annual production. A “small” oil refinery can produce up to 3 million gallons of fuel per day. Its annual RFS obligation would include 20 million gallons of biodiesel, the amount some small plants produce in a year.
  • A U.S. Court of Appeals decision from January 2020 limited EPA’s authority to grant small refinery exemptions. EPA should immediately apply the court’s ruling to all pending and future exemptions.
  • EPA also ignored a 2017 U.S. Court of Appeals order to reconsider a waiver of 500 million gallons of renewable fuel. It is long past time for the agency to address the shortfall.

NBB Thanks 24 Senators for Opposing RFS Waiver

Senators' letter to EPA Administrator Wheeler says RFS waiver is unjustified


 Contact: Paul Winters

WASHINGTON, DC - Today, Sens. Joni Ernst (R-IA), Tina Smith (D-MN), Chuck Grassley (R-IA), Debbie Stabenow (D-MI), and 20 additional senators sent a letter to President Donald Trump urging him to immediately reject petitions for a general waiver of the 2020 Renewable Fuel Standard. The National Biodiesel Board (NBB) thanks the Senators for supporting biodiesel producers and echoes their conclusion that waiving the RFS will cause unnecessary harm to the rural economy.

Kurt Kovarik, NBB's VP of Federal Affairs, said, "America's biodiesel producers appreciate the strong leadership of Senators Ernst, Smith, Grassley and Stabenow in opposing efforts to undermine the Renewable Fuel Standard. Biodiesel and renewable diesel producers are an important part of the nation's critical agriculture infrastructure, which is already experiencing painful effects of the national economic crisis. Maintaining a strong RFS will be important to the rural economy's recovery.

"An RFS waiver would simply prevent biofuel producers, farmers and other agricultural sectors from fully sharing in any economic recovery this year. RFS requirements do not contribute to the crisis, because they are set as percentages that rise and fall in direct proportion with transportation fuel demand."

Made from an increasingly diverse mix of resources such as recycled cooking oil, soybean oil and animal fats, biodiesel is a renewable, clean-burning diesel replacement that can be used in existing diesel engines without modification. It is the nation's first domestically produced, commercially available advanced biofuel. NBB is the U.S. trade association representing the entire biodiesel and renewable diesel value chain, including producers, feedstock suppliers, and fuel distributors.
