The U.S. EPA has released updated renewable identification number (RIN) data, reporting that nearly 1.62 billion RIN were generated under the Renewable Fuel Standard in September, down from 1.65 billion generated during the same period of last year.

Nearly 49.25 million D3 cellulosic biofuel RINs were generated in September, including 38.85 million generated for compressed renewable natural gas (RNG) by domestic producers, 7.4 million generated for liquified RNG by domestic producers, 2.97 million generated for compressed RNG by importers, and 25,800 generated for liquefied RNG by importers.

Total D3 RIN generation for the first nine months of 2021 reached more than 364.66 million. That volume includes 287.35 million generated for compressed RNG by domestic producers, 52.92 million generated for liquefied RNG by domestic producers, 23.2 million generated for compressed RNG by importers, 945,700 generated for liquefied RNG by importers, and 81,426 generated for cellulosic ethanol by domestic producers.

Nearly 384.81 million D4 biomass-based diesel RINs were generated in September, including 209.31 million generated for biodiesel by domestic producers, 84.87 million generated for nonester renewable diesel by domestic producers, 72.45 million generated for nonester renewable diesel by foreign entities, 17.69 million generated for biodiesel by importers, and 480,195 generated for renewable jet fuel by domestic producers.

Total D4 RIN generation for the first three quarters of this year reached 3.39 billion. That volume includes 1.89 billion generated for biodiesel by domestic producers, 853.98 million generated for nonester renewable diesel by domestic producers, 463.12 million generated for nonester renewable diesel by foreign entities, 176.73 million generated for biodiesel by importers, 6.19 million generated for renewable jet fuel by domestic producers, and 4.86 million generated for nonester renewable diesel by importers.

Nearly 23.21 million D5 advanced biofuel RINs were generated in September, including 10.76 million generated for ethanol by importers, 8.36 million generated for nonester renewable diesel by domestic producers, 1.8 million generated for ethanol by domestic producers, 1.48 million generated for naphtha by domestic producers, 405,910 generated for LPG by domestic producers, 269,902 generated for compressed RNG by domestic producers, and 134,866 generated for renewable heating oil by domestic producers.

Total D5 RIN generation for the first nine months of this year reached 166.73 million. That volume includes 75.67 million generated for nonester renewable diesel by domestic producers, 48.77 million generated for ethanol by importers, 19.29 million generated for ethanol by domestic producers,  17.33 million generated for naphtha by domestic producers, 3.26 million generated for LPG by domestic producers, 1.44 million generated for renewable heating oil by domestic producers, and 977,943 generated for compressed RNG by domestic producers.

Nearly 1.16 billion D6 renewable fuel RINs were generated in September, including 1.15 billion generated for ethanol by domestic producers, 12.2 million generated for nonester renewable diesel by foreign entities, and 1.22 million generated for ethanol by importers.

Total D6 RIN generation for the first three quarters of 2021 reached 10.48 billion. That volume includes 10.38 billion generated for ethanol by domestic producers, 92.57 million generated for nonester renewable diesel by foreign entities, and 8.81 million generated for ethanol by importers.

No D7 cellulosic diesel RINs have been generated so far this year.

Total RIN generation for the first nine months of 2021 reached more than 14.4 billion, up from 13.4 billion generated during the same period of last year.
