US RFS, RIN markets face uncertainty under Trump

Oil, biofuel groups meet to align on RFS policy

Oil, biofuel groups meet to align on RFS policy

New York, 27 March (Argus) — Energy and farm groups met last week at the American Petroleum Institute to negotiate a joint request for President Donald Trump's administration as it develops new biofuel blend mandates, according to five people familiar with the matter. The private meeting involved groups from across the supply chain, including representatives of feedstock suppliers, biofuel producers, fuel marketers, and oil refiners with Renewable Fuel Standard (RFS) obligations. The groups coordinated earlier this year around a letter to the Trump administration on the need to update the RFS and are now seeking agreement on other program elements. According to the people familiar with the matter, the groups agree on pushing the Environmental Protection Agency (EPA) to set higher blend mandates under the program's D4 biomass-based diesel and D5 advanced biofuel categories. Groups support slightly different volume targets that are nevertheless all in "a rounding number of each other" in the D4 category, according to one lobbyist. But there is still disagreement about whether to ramp up mandates quickly in 2026 or provide a longer runway to higher volumes. Clean Fuels Alliance America and farm groups have publicly supported a biomass-based diesel mandate of at least 5.25bn USG starting next year, which could justify a broader advanced biofuel mandate above 9bn USG, according to the people familiar, though others worry about fuel cost impacts if mandates spike so quickly. The current mandate for 2025 is 7.33bn USG in the advanced biofuels category, including a 3.35bn USG mandate for the biomass-based diesel subcategory, so the volumes being pushed for future years would be a steep increase. The RFS, highly influential for fuel and commodity crop prices, requires oil refiners and importers to blend annual amounts of biofuels into the conventional fuel supply or buy Renewable Identification Number (RIN) credits from those who do. The idea behind the groups' coordination is that the Trump administration might more quickly finalize RFS updates if lobbyists with a history of sparring over biofuel policy can articulate a shared vision of the program's future. One person familiar said the effort comes after the Trump administration directed industry to align biofuel policy goals, though others said they understood the coordination as largely voluntary. EPA did not provide comment. There is less agreement around the program's D6 conventional biofuel category, which is mostly met by corn ethanol. Oil groups have in the past criticized EPA for setting the implied D6 mandate at 15bn USG, above the amount of ethanol that can feasibly be blended into gasoline, though excess biofuels from lower-carbon categories can be used to meet conventional obligations. Ethanol interests support setting the D6 mandate even higher than 15bn USG, which could be a tough sell. The discussions to date have not involved targets for D3 cellulosic biofuels, a relatively small part of the program. A proposal to lower 2024 volumes has hurt D3 credit prices, signaling that future mandates are effectively optional, according to frustrated biogas executives , and has reduced the salience of the issue for other groups. A proposal from President Joe Biden's administration to create a new category called "eRINs" to credit biogas used to power electric vehicles has similarly not come up. "We're not expecting to see any attempt to include eRINs in this next [RFS] proposal," Renewable Fuels Association president Geoff Cooper told Argus earlier this month. The meeting last week was largely oriented around the RFS, though a National Association of Truck Stop Operators representative raised the issue of tax policy too. The group has been frustrated by the expiration of a long-running blenders credit and the introduction this year of a less generous credit for refiners, which is only partially implemented and has spurred a sharp decline in biomass-based diesel production. But others involved in negotiations, while they acknowledge tax uncertainty could hurt their case for strong mandates, are trying to avoid contentious topics and focus mostly on volumes. Republican lawmakers are separately weighing whether to keep, repeal, or adjust that credit to help out fuel from domestic crops, and there is no telling how long that debate might take to resolve. Another thorny issue discussed at the meeting is RFS exemptions for small refineries. Biofuel producers strongly oppose such waivers and say that exempted volumes should at least be reallocated among facilities that still have obligations. Oil groups have their own views, though it is unclear how involved the American Fuel and Petrochemical Manufacturers — which represents some small refiners and has generally been more critical of the RFS than the American Petroleum Institute — are in discussions. EPA is aiming to finalize new volume mandates by the end of this year , people familiar with the administration's thinking have said, though timing for a proposal is still unclear. Future conversations among energy and farm groups to solidify points of unity — and strategize around how to downplay disagreements — are likely, lobbyists said. RIN prices rally Speculation over the trajectory of the RFS, and the potential for higher future volumes, supported soybean oil futures and widened the bean oil-heating oil (BOHO) spread. The BOHO spread maintains a positive correlation with D4 RIN prices as a widening value raises demand for D4 credits as biofuel producers look to offset higher production costs. Thursday's session ended with current-year ethanol D6 credits valued between 79¢/RIN and 82¢/RIN, while their D4 counterparts held at a premium and closed with a range of 84¢/RIN to 89¢/RIN. These gains each measured more than 5.5pc growth relative to Wednesday's values.
