According to EPA data, 1.82 billion Renewable Identification Numbers (RINs) were generated in March 2025, marking a pivotal point in clean fuel credit supply and compliance trends.

The U.S. EPA released updated renewable identification number (RIN) data on April 11. It reported that 1.82 billion RINs were generated under the Renewable Fuel Standard in March, down from 1.93 billion generated during the same month of 2024. Approximately 5.34 billion RINs were generated during the first quarter of 2025, down from 5.88 billion last year. 

Nearly 8.76 million D3 cellulosic biofuel RINs were generated in March, including 6.64 million generated for cellulosic ethanol by domestic producers, 2.11 million generated for renewable natural gas (RNG) by domestic producers, and 1,625 generated for compressed RNG by domestic producers. 

Total D3 RIN generation for the first three months of 2025 reached 175.02 million. That volume includes 145.46 million generated for RNG by domestic producers, 20.25 million generated for cellulosic ethanol by domestic producers, 7.37 million generated for RNG by importers, and 1.93 million generated for compressed RNG by domestic producers.

Approximately 573.08 million D4 biomass-based diesel RINs were generated in March, including 375.16 million generated for nonester renewable diesel by domestic producers, 143.75 million generated for biodiesel by domestic producers, 21.55 million generated for nonester renewable diesel by importers, 12.64 million generated for nonester renewable diesel by foreign entities, 7.97 million generated for renewable jet fuel by foreign entities, 6.15 million generated for renewable jet fuel by domestic producers, and 5.85 million generated for biodiesel by importers. 

Total D4 RIN generation for the first quarter of this year reached 1.51 billion. That volume includes 1.04 billion generated for nonester renewable diesel by domestic producers, 352.79 million generated for biodiesel by domestic producers, 44.88 million generated for renewable jet fuel by domestic producers, 20.61 million generated for renewable jet fuel by foreign entities, 20.17 million generated for biodiesel by importers, 21.55 million generated for nonester renewable diesel by importers, and12.64 million generated or nonester renewable diesel by foreign entities.

More than 4.14 million D5 advanced biofuel RINs were generated in March, including 11.17 million generated for nonester renewable diesel by domestic producers, 10.96 million generated for naphtha by domestic producers, 2.32 million generated for ethanol by domestic producers, 339,196 generated for renewable heating oil by domestic producers, and 65,823 generated for LPG by domestic producers. 

Total D5 RIN generation for the first quarter of 2025 reached 72.4 million. That volume includes 36.42 million generated for naphtha by domestic producers, 28.26 million generated for nonester renewable diesel by domestic producers, 6.74 million generated for ethanol by domestic producers, 789,947 generated for renewable heating oil by domestic producers, 83,683 generated for compressed RNG by domestic producers, 65,823 generated for LPG by domestic producers, and 48,528 generated for RNG by domestic producers.

More than 1.21 billion D6 renewable fuel RINs were generated in March, nearly all for ethanol by domestic producers. An additional 988,011 D6 RINs were generated for ethanol by importers. 

Total D6 RIN generation for the first three months of the year reached 3.58 billion, nearly all for ethanol by domestic producers, with 3.3 million generated for ethanol by importers and 153,911 generated for biodiesel by domestic producers. 

According to the EPA, 54,155 D7 cellulosic diesel RINs were generated in March by importers for cellulosic heating oil. Total D7 RIN generation for the first quarter of 2025 reached 82,937, all of which were generated for cellulosic heating oil by importers.
