In the 20th year of the Renewable Fuel Standard (RFS) program, the White House has established the renewable fuel volume requirements for 2026 and 2027 at the highest levels in program history. The Set 2 final rule, announced at the White House Great American Agriculture Celebration in front of 650 invited attendees, realigns the program with Congress’ intent to increase the use of homegrown American biofuels.
“Today’s announcement is truly historic for our nation’s farmers and energy producers. These numbers represent the highest levels of biofuels ever required to be blended into our fuel supply,” says Brooke Rollins, Secretary of Agriculture. “With President Trump and Administrator Zeldin’s leadership, these historically high volumes are expected to create a $3 to $4 billion increase in net farm income. The Renewable Fuel Standard Set 2 Rule will create a $31 billion dollar value for American corn and soybean oil for biofuel production in 2026, which is $2 billion more than in 2025. Our farmers are stepping up to grow American energy dominance.”
Just this week, EPA renewed emergency waivers for E15 gasoline sales during the summer driving season.
What Does the Set 2 Final Rule Mean for Farmers
To meet the 2026 and 2027 volume levels, EPA estimates biodiesel and renewable diesel production and use will need to increase by more than 60% versus 2025 volumes. The increase was above the initial proposal.
“The proposal that we saw nine months ago was extremely robust,” explained Kurt Kovarik of the Clean Fuels Alliance America. “In fact, our industry, along with the petroleum sector and the soybean growers, asked for a volume requirement for 2026 of 5.25 billion gallons. They proposed 5.61 billion gallons. And today’s proposal is right in that neighborhood between 5 to perhaps as high as 5.6 or 5.7. There’s a little bit of math yet that needs to be done.”
He said that in 2025, biodiesel and renewable diesel facilities were forced to shut down or run far below prior-year production levels due to market uncertainty. U.S. biodiesel production declined by one-third in 2025, compared to 2024.
“Biodiesel and renewable diesel represent 10% of the value of every bushel of U.S.-grown soybeans, contributing to President Trump’s desire for American energy dominance and domestic market demand for agriculture commodities,” said Kovarik. “American farmers and other feedstock providers are eager for the growing domestic clean fuel market to drive value in agriculture, along with economic growth and job creation in rural communities. American consumers are desperate for secure, affordable domestic energy. Today’s rule is a clear win for the nation’s energy security.”
With the benefits Set 2 will bring to America’s farmers, EPA estimates the rule will generate more than $10 billion for rural economies and create more than 100,000 new jobs in the agricultural and manufacturing sectors. To provide continued certainty for American corn growers and ethanol producers, EPA will maintain the 15 billion conventional biofuel level for 2026 and 2027.
What are Renewable Volume Obligations?
RVOs are targets set by EPA to determine how much renewable fuel must be blended into the U.S. transportation fuel supply. EPA determines the total volume of different categories of biofuels that should be used in the country for multi-year periods. Once decided, EPA converts the total volumes into percentage standards, which represent the ratio of renewable fuel to the total amount of gasoline and diesel expected to be consumed in the U.S. that year.
Each “obligated party,” typically refiners and importers of gasoline and diesel, calculates its RVO by multiplying EPA’s percentage standards by the total volume of non-renewable gasoline and diesel they produce or import. To prove they have met their RVO, obligated parties must use a serial number attached to each gallon of biofuel, known as Renewable Identification Numbers (RINs). When the biofuel is blended into the fuel supply, the RIN is “separated” from the physical fuel.
At the end of the compliance year, obligated parties must submit to EPA enough RINs to cover their specific RVO. If a refiner blends more biofuel than required, they can sell their excess RINs to other refiners who have not met their obligations.
Adjusted Small Refinery Exemptions
The EPA also finalized the reallocation of the volumes from Small Refinery Exemptions from 2023 through 2025. Those are now set at 70%.
“Adding it to the top line volume for 2026 and 2027, the volumes that were waived over those three years will be made up in 2026 and 2027,” Kovarik. “For our industry, that’s somewhere between an additional 200 to 250 million gallons a year.”
He says that is on top of the already robust minimum volume that EPA set. The agency claims the RFS rule will create $31 billion in value for American corn and soybean oil.
Renewable Fuels Association (RFA) President and CEO Geoff Cooper noted that while they advocated for full reallocation of the 2023-2025 SREs, the 70 percent reallocation included in today’s rule is better than other options that were under consideration. EPA had proposed 50 percent reallocation as an option and also solicited public feedback on no reallocation at all.
“We continue to believe small refinery exemptions are completely unjustified, and the SRE petition process—including EPA’s reliance on the Department of Energy’s ‘scoring matrix'—is fundamentally flawed,” Cooper said. “SREs distort the market, undermine fair competition, and destabilize the RFS program. And while RFA appreciates EPA’s efforts to minimize market disruptions by reallocating most of the renewable volume lost to SREs, we believe the Agency has a duty to fully restore all exempted volumes.”
RVO Reaction Pours In
The Renewable Fuels Association (RFA) and other farm groups applaud the RVO announcement from EPA.
“Today’s RFS rule supports continued growth in American-made renewable fuels like ethanol and brings much-needed certainty and stability to the marketplace,” said RFA on X.com.

“Congress intended year-to-year renewable fuel blending to increase under the RFS and today’s announcement with the highest-ever volume obligations helps fulfill their intention,” said Brian Jennings, CEO for American Coalition for Ethanol. “We’ve consistently advocated for strong final blending obligations for 2026 and 2027, reflecting the full potential of the RFS and ensuring small refinery exemptions (SREs) do not erode demand for renewable fuels.”
Jennings says the integrity of the RFS depends on ensuring volume obligations translate into real-world demand. Any gap between required volumes and actual blending undermines the program and creates uncertainty for ethanol producers, farmers, and rural communities.
“We appreciate President Trump, Administrator Zeldin and Secretary Rollins for delivering strong RVO volumes and doing so in a way that recognizes the importance of American farmers,” said NSP Chair Amy France, a farmer from Scott City, Kan. “These volumes provide critical certainty for sorghum producers and help strengthen demand across the biofuels sector.”
NSP also highlighted EPA’s decision to reallocate 70 percent of previously exempted volumes, helping ensure that promised demand is realized.
“Maintaining the integrity of the Renewable Fuel Standard is essential,” France said. “Reallocating those gallons helps protect the market opportunities farmers depend on. We need to build on this momentum and get year-round E15 across the finish line.”
Ohio farmer and National Corn Growers Association President Jed Bower, who was present at the White House for the announcement, also weighed in on the latest volumes.
“Our deep thanks go to President Trump and Administrator Zeldin for releasing these robust RVO numbers in an exceptionally timely manner and, appropriately, during an event honoring America’s farmers. This action provides certainty to corn farmers across the country who rely on a stable biofuels industry. Today’s announcement, coupled with the Trump administration’s E15 summertime waiver earlier this week, is a positive move for the nation’s corn growers who are navigating an exceptionally difficult economic environment. There is still more to be done to help our growers, and we look forward to working side-by-side with the president and our allies in Congress to get permanent year-round E15 legislation over the finish line.”
Fuel and Fertilizer Costs Surge
While there’s hope that embracing biofuels can help bolster the farm economy and lower prices at the pump, farmers are feeling the fallout of higher oil prices. According to AAA on Friday, the national average for a gallon of diesel fuel was $5.38. That’s nearly $2 per gallon higher than it was just a year ago, and it’s happening right as farmers gear up for the spring planting season.
“To help lower gasoline prices for farmers and consumers, this week, I issued an emergency order to allow immediate sales of E-15 — and just as I promised in the campaign, I’m seeking Congressional action to allow E-15 all-year-round,” said President Trump.
Fertilizer prices are also significantly higher in the last few weeks. While some farmers pre-applied acres last fall and others bought earlier in 2026, there are still a number of acres left to cover.
