The number of renewable identification numbers generated in August for ethanol under the Renewable Fuel Standard remained steady from July, the Environmental Protection Agency reported on Thursday.
EPA reported 1.2 billion D6 ethanol RINs in August, almost all for ethanol by domestic producers. That was unchanged from July.
For D4 biomass-based diesel, 693 million RINs were generated in August, down from 545.8 million in 2025.
D5 advanced biofuel generation totaled 23.1 million RINS.
The D4 and D5 combined total of 716.2 million fell below July's total of 823.2 million.
Matt Gammans, assistant professor of agricultural policy at North Dakota State University, says the RIN generation report suggests a lower production rate than what will be needed to hit the Renewable Volume Obligation.
"That said, generation has increased from last year. The recent decline will need to be offset by stronger production later in the year or a draw on banked credits. If we get another report this low next month, we might expect to see a positive response in RIN prices," Gammans said.
