Nearly 1.95 billion renewable identification numbers (RINs) were generated under the Renewable Fuel Standard in September, up from 1.73 billion generated during the same month of last year, according to data released by the U.S. EPA on Oct. 19. Total RIN generation for the first nine months of 2023 reached 17.41 billion, up from 15.63 billion generated during the same period of 2022.

More than 59.1 million D3 cellulosic biofuel RINs were generated in September. The vast majority—52.02 million—were generated for compressed renewable natural gas (RNG) by domestic producers, with 3.36 million generated for liquefied RNG by importers, 3.24 million generated for liquefied RNG by domestic producers, 342,002 generated for compressed RNG by importers, and 146,298 generated for cellulosic ethanol by domestic producers. 

Total D3 RIN generation for the first nine months of 2023 reached 505.32 million. That volume includes 441.14 million generated for compressed RNG by domestic producers, 34.93 million generated for liquefied RNG by domestic producers, 24.01 million generated for liquefied RNG by importers, 4.3 million generated for compressed RNG by importers, and 947,003 generated for cellulosic ethanol by domestic producers. 

More than 674.96 million D4 biomass-based diesel RINs were generated in September, including 380.65 million generated for nonester renewable diesel by domestic producers, 214.95 million generated for biodiesel by domestic producers, 60.7 million generated for biodiesel by importers, 13.2 million generated for nonester renewable diesel by foreign entities, 2.41 million generated for renewable jet fuel by foreign entities and 1.05 million generated for renewable jet fuel by domestic producers. 

Total D4 RIN generation for the first three quarters of this year reached 5.7 billion. That volume includes 2.81 billion generated for nonester renewable diesel by domestic producers, 1.88 billion generated for biodiesel by domestic producers, 506.05 million generated for biodiesel by importers, 473.12 million generated for nonester renewable diesel by foreign entities, 15.85 million generated for renewable jet fuel by domestic producers, 13.68 million generated for renewable jet fuel by foreign entities, and 336,877 generated for renewable heating oil by domestic producers.

More than 35.4 million D5 advanced biofuel RINs were generated in September, including 19.4 million generated for ethanol by importers, 7 million generated for nonester renewable diesel by domestic producers, 5 million generated for naphtha by domestic producers, 2.57  million generated for ethanol by domestic producers, 853,655 generated for renewable heating oil by domestic producers, 475,5004 generated for LPG by domestic producers, and 101,931 generated for compressed RNG by domestic producers. 

Total D5 RIN generation for the first nine months of this year reached 196.84 million. That volume includes 91.73 million generated for nonester renewable diesel by domestic producers, 55.04 million generated for naphtha by domestic producers, 22.17 million generated for ethanol by domestic producers, 19.4 million generated for ethanol by importers, 3.71 million generated for renewable heating oil by domestic producers, 3.49 million generated for LPG by domestic producers, and 1.3 million generated for compressed RNG by domestic producers.

Nearly 1.18 billion D6 renewable fuel RINs were generated in September, including 1.17 billion generated for ethanol by domestic producers, 3.22 million generated for biodiesel by importers, 1.52 million generated for biodiesel by domestic producers, 1.27 million generated for ethanol by importers, and 693,816 generated for nonester renewable diesel by foreign entities.

Total D6 RIN generation for the first three quarters of 2023 reached 11.01 billion. That volume includes 10.89 billion generated for ethanol by domestic producers, 101.13 million generated for nonester renewable diesel by foreign entities, 8.82 million generated for ethanol by importers, 3.22 million generated for biodiesel by importers, 1.6 million generated for biodiesel by domestic producers, 1.8 million generated for renewable jet fuel by domestic producers, and 327,746 generated for nonester renewable diesel by domestic producers.

No D7 cellulosic diesel RINs were generated under RFS in September. Total D7 RIN generation for the first nine months of 203 reached 166,084, all of which were generated for cellulosic heating oil by importers.
