ANKENY, IOWA (June 13, 2025) — The Iowa Biodiesel Board has welcomed the Environmental Protection Agency’s proposed Renewable Fuel Standard volumes for 2026 and 2027, calling the record-setting targets for biomass-based diesel a major win for domestic biodiesel producers.
The proposal sets biomass-based diesel volumes at 7.12 billion RINs in 2026 and 7.50 billion RINs in 2027. Based on conversion rates provided by EPA, that equates to an estimated 5.61 billion gallons in 2026 — the highest-ever proposed levels under the RFS.
Grant Kimberley, executive director of the Iowa Biodiesel Board, issued the following statement:
“While this proposal has some significant program changes that will require further study for us to better understand, over all it reflects the strength, resilience, and growth potential of America’s biodiesel industry. The volumes signal real opportunity for domestic producers, especially here in Iowa, and we appreciate the EPA’s recognition of what this industry is capable of delivering.
“We thank the Trump administration for recognizing that American-made biofuels should be a national priority, and for setting the stage for today’s historic growth in biomass-based diesel.
“For Iowa, these volumes likely mean something even more immediate — getting our idled biodiesel plants back up and running. That’s good news for jobs, for soybean farmers and for communities that rely on biofuels as a driver of economic growth.
“While what happens with small refinery exemptions remains to be seen and is very important to the final outcome, today’s news overall is a win for clean energy, agriculture and American manufacturing.”
Kimberley also thanked Iowa’s Congressional delegation — Senators Chuck Grassley and Joni Ernst, and Representatives Ashley Hinson, Mariannette Miller-Meeks, Randy Feenstra, and Zach Nunn — for their continued leadership and unified support for Iowa’s biofuel producers and soybean growers.
