Nearly 1.84 billion renewable identification numbers (RINs) were generated under the Renewable Fuel Standard in April, up from 1.71 billion generated during the same month of 2022, according to data released by the U.S. EPA on May 18. Total RIN generation for the first four months of 2023 reached 7.23 billion, up from 6.66 billion generated during the first four months of last year.

Nearly 61.93 million D3 cellulosic biofuel RINs were generated in April, including 53.91 million generated for compressed renewable natural gas (RNG) by domestic producers, 4.36 million generated for liquefied RNG by domestic produces, 3.46 million generated for liquefied RNG by importers, and 201,463 generated for compressed RNG by importers.

Total D3 RIN generation for the first four months of the year was at 180.83 million. That volume includes 157.69 million generated for compressed RNG by domestic producers, 12.46 million generated for liquefied RNG by domestic producers, 9.82 million generated for liquefied RNG by importers, 563,836 generated for compressed RNG by importers, and 289,648 generated for ethanol by domestic producers.

More than 602.72 million D4 RINs were generated in April, including 284.79 million generated for nonester renewable diesel by domestic producers, 200.41 million generated for biodiesel by domestic producers, 61.7 million generated for nonester renewable diesel by foreign entities, 51.97 million generated for biodiesel by importers, 2.24 million generated for renewable jet fuel by foreign entities, 1.46 million generated for renewable jet fuel by domestic producers, and 146,317 generated for renewable heating oil.

Total D4 RIN generation for the first four months of 2023 reached nearly 2.26 billion. That volume includes 1.05 billion generated for nonester renewable diesel by domestic producers, 748.14 million generated for biodiesel by domestic producers, 232.73 million generated for nontester renewable diesel by foreign entities, 212.6 million generated for biodiesel by importers, 6.88 million generated for renewable jet fuel by foreign entities, 4.31 million generated for renewable jet fuel by domestic producers, and 336,877 generated for renewable heating oil by domestic producers.

More than 17.61 million D5 advanced biofuel RINs were generated in April, including 7.89 million generated for nonester renewable diesel by domestic producers, 3.01 million generated for naphtha by domestic producers, 20.6 million generated for ethanol by domestic producers, 586,374 generated for compressed RNG by domestic producers, 521,201 generated for renewable heating oil by domestic producers, and 346,474 generated for LPG by domestic producers.

Total D5 RIN generation for the first four months of the year reached 72.71 million. That volume includes 31.3 million generated for nonester renewable diesel by domestic producers, 27.8 million generated for naphtha by domestic producers, 9.83 million generated for ethanol by domestic producers, 1.61 million generated for renewable heating oil by domestic producers, 1.43 million generated for LPG by domestic producers, and 733,478 generated for compressed RNG by domestic producers.

Nearly 1.16 billion D6 renewable fuel RINs were generated in April, including 1.14 billion generated for ethanol by domestic producers, 16.67 million generated for renewable diesel by foreign entities, and 1.06 million generated for ethanol by importers.

Total D6 RIN generation for the first four months of 2023 reached 4.72 billion. That volumes includes 4.66 billion generated for ethanol by domestic producers, 56.03 million generated for nonester renewable diesel by foreign entities, and 2.26 million generated for ethanol by importers,

According to the EPA, 69,961 D7 cellulosic diesel RINs were generated in April, all for cellulosic heating oil by importers. No other D7 RIN have been generated so far this year.
