The U.S. EPA on Jan. 17 released updated data showing that more than 25.22 billion renewable identification numbers (RINs) were generated under the Renewable Fuel Standard in 2024, up from 23.85 billion in 2023.

On a volume basis, the 25.22 billion RINs generated last year equates to 21.64 billion gallons of ethanol, biodiesel, renewable diesel, sustainable aviation fuel (SAF), renewable natural gas (RNG) and other biobased fuels. The volume equivalent for 2023 RIN generation equates to approximately 20.72 billion gallons.

The 25.22 billion RINs generated last year includes 14.9 billion generated for non-cellulosic ethanol, 6.01 billion generated for nonester renewable diesel, 3.11 billion generated for biodiesel, 804.88 million generated for compressed RNG, 178.98 million generated for renewable jet fuel, 93.79 million generated for naphtha,  74.35 million generated for liquefied RNG, 43.26 million generated for cellulosic ethanol, 4.6 million generated for renewable heating oil, 3.93 million generated for renewable gasoline, 1.35 million generated for RNG, 283,259 generated for cellulosic heating oil, and 204,556 generated for LPG. 

Nearly 23.71 billion of the RINs generated last year represented domestic production, with 854.61 million generated by importers and 650.52 million generated by foreign entities.

The new data shows that nearly 1.96 billion RINs were generated in December, up slightly from the 1.93 billion RINs that were generated under the RFS during the same month of 2023.

More than 85.94 million D3 cellulosic biofuel RINs were generated in December, including 68.24 million generated for compressed RNG by domestic producers, 9.38 million generated for cellulosic ethanol by domestic producers, 4.21 million generated for liquefied RNG by domestic producers, 2.25 million generated for liquefied RNG by importers, 1.59 million generated for compressed RNG by importers, and 286,665 generated for RNG by domestic producers. 

Total D3 RIN generation for 2024 reached 922.69 million. That volume includes 796.32 million generated for compressed RNG by domestic producers, 43.26 million generated for cellulosic ethanol by domestic producers, 39.51 million generated for liquefied RNG by domestic producers, 34.84 million generated for liquefied RNG by importers, 7.41 million generated for compressed RNG by importers, and 1.35 million generated for RNG by domestic producers.

Nearly 898.87 million D4 biomass-based diesel RINs were generated in December, including 517.73 million generated for nonester renewable diesel by domestic producers, 262.01 million generated for biodiesel by domestic producers, 55.93 million generated for nonester renewable diesel by importers, 47.09 million generated for biodiesel by importers, 7.2 million generated for nonester renewable diesel by foreign entities, 5.45 million generated for renewable jet fuel by foreign entities, and 3.46 million generated for renewable jet fuel by domestic producers. 

Total D4 RIN generation for 2024 reached 9.16 billion. That volume includes 5.17 billion generated for nonester renewable diesel by domestic producers, 2.49 billion generated for biodiesel by domestic producers, 597.08 million generated for biodiesel by importers, 533.48 million generated for nonester renewable diesel by foreign entities, 191.21 million generated for nonester renewable diesel by importers, 117.04 million generated for renewable jet fuel by foreign entities, 61.87 million generated for renewable jet fuel by domestic producers, and 157,995 generated for renewable heating oil by domestic producers.

Approximately 27.07 million D5 advanced biofuel RINs were generated in December, including 10.92 million generated for nonester renewable diesel by domestic producers, 12.76 million generated for naphtha by domestic producers, 2.76 million generated for ethanol by domestic producers, 481,371 generated for renewable heating oil by domestic producers, 120,576 generated for compressed RNG by domestic producers, and 31,748 generated for LPG by domestic producers. 

Total D5 RIN generation for 2024 reached 243.23 million. That volume includes 93.79 million generated for naphtha by domestic producers, 114.13 million generated for nonester renewable diesel by domestic producers, 28.69 million generated for ethanol by domestic producers, 4.44 million generated for renewable heating oil by domestic producers, 1.16 million generated for compressed RNG by domestic producers, and 1.02 million generated for LPG by domestic producers.

Nearly 1.3 billion D6 renewable fuel RINs were generated in December, nearly all for ethanol by domestic producers. More than 1.21 million D6 RINs were generated for ethanol by importers and 301,667 million were generated for biodiesel by domestic producers. 

Total D6 RIN generation for 2024 reached 14.89 billion. That volume includes 14.85 billion generated for ethanol by domestic producers, 14.45 million generated for ethanol by importers, 13.41 million generated for biodiesel by domestic producers, 9.35 million generated for biodiesel by importers, 3.93 million generated for renewable gasoline by domestic producers, 250,191 generated for nonester renewable diesel by domestic producers, and 64,809 generated for renewable jet fuel by domestic producers.

According to EPA, 18,084 D7 cellulosic diesel RINs were generated in December. Total D7 RIN generation for the full year reached 283,259, all of which were generated for cellulosic heating oil by importers.
