The U.S. EPA on May 15 released data showing nearly 1.79 billion renewable identification numbers (RINs) were generated under the Renewable Fuels Standard in April, down from 2.09 million generated during the same month of last year. Total RIN generation for the first four months of 2025 reached 7.12 billion, down from 7.97 billion generated during the same period of 2024.
More than 11.2 million D3 cellulosic biofuel RINs were generated in April, including 8.76 million generated for cellulosic ethanol by domestic producers, 2.44 million generated for renewable natural gas (RNG) by domestic producers and 2,822 generated for compressed RNG by domestic producers.
Total D3 RIN generation for the first four months of 2025 reached 275.3 million. That volume includes 233.08 million generated for RNG by domestic producers, 29.02 million generated for cellulosic ethanol by domestic producers, 11.2 million generated for RNG by importers, and 2.01 million generated for compressed RNG by domestic producers.
More than 591.59 million D4 biomass-based diesel RINs were generated in April, including 403.6 million generated for nonester renewable diesel by domestic producers, 150.74 million generated for biodiesel by domestic producers, 21.49 million generated for renewable jet fuel by domestic producers, 7.23 million generated for renewable jet fuel by foreign entities, 6.48 million generated for nonester renewable diesel by foreign entities, and 2.06 million generated for biodiesel by importers.
Total D4 RIN generation for the first four months of this year reached 2.1 billion. That volume includes 1.44 billion generated for nonester renewable diesel by domestic producers, 503.54 million generated for biodiesel by domestic producers, 66.36 million generated for renewable jet fuel by domestic producers, 27.84 million generated for renewable jet fuel by foreign entities, 22.23 million generated for biodiesel by importers, 21.55 million generated for nonester renewable diesel by importers, and 19.12 million generated for nonester renewable diesel by foreign entities.
Nearly 22.9 million D5 advanced biofuel RINs were generated in April, including 12.29 million generated for naphtha by domestic producers, 5.48 million generated for nonester renewable diesel by domestic producers, and 5.13 million generated for ethanol by domestic producers.
Total D5 RIN generation for the first four months of 2025 reached 95.33 million. That volume includes 48.71 million generated for naphtha by domestic producers, 33.74 million generated for nonester renewable diesel by domestic producers, 11.86 million generated for ethanol by domestic producers, 789,947 generated for renewable heating oil by domestic producers, 708,566 generated for compressed RNG by domestic producers, 65,823 generated for LPG by domestic producers, and 52,233 generated for RNG by domestic producers.
More than 1.16 billion D6 renewable fuel RINs were generated in April, nearly all for ethanol by domestic producers, with 823,844 generated for ethanol by importers.
Total D6 RIN generation for the first four months of the year reached 4.74 billion, nearly all for ethanol by domestic producers. Approximately 4.12 million D6 RINs were generated for ethanol by importers, with 153,911 generated for biodiesel by domestic producers.
According to the EPA, 23,802 D7 cellulosic diesel RINs were generated in April, all for cellulosic heating oil by importers. Total D7 RIN generation for the first four months of 2025 reached 106,739, with all of those RINs generated for cellulosic heating oil by importers.
