Total RIN generation for the first half of 2025 reached 11.17 billion, down 8% when compared to the 12.18 billion generated during the same period of 2024.

More than 6.54 million D3 RINs were generated in June, including 5.3 million generated for cellulosic ethanol by domestic producers, 1.23 million generated for renewable natural gas (RNG) by domestic producers, and 3,847 generated for compressed RNG by domestic producers. 

Total D3 RIN generation for the first six months of 2025 reached 493.38 million, up 31% when compared to the same period of last year. That volume includes, 431.54 million generated for RNG by domestic producers, 41.25 million generated for cellulosic ethanol by domestic producers, 18.45 million generated for RNG by importers, and 2.13 million generated for compressed RNG by domestic producers. 

More than 629.08 million D4 biomass based diesel RINs were generated in June, including 445.82 million generated for nonester renewable diesel by domestic producers, 145.17 million generated for biodiesel by domestic producers, 28.85 million generated for renewable jet fuel by domestic producers, 9.05 million generated for renewable jet fuel by foreign entities, and 192,477 generated for biodiesel by importers. 

Tota D4 RIN generation for the first half of 2025 reached 3.33 billion, down 25% when compared to the same period of 2024. That volume includes 2.29 billion generated for nonester renewable diesel by domestic producers, 793.33 million generated for biodiesel by domestic producers, 125.5 million generated for renewable jet fuel by domestic producers, 45.95 million generated for renewable jet fuel by foreign entities, 27.56 million generated for nonester renewable diesel by foreign entities, 24 million generated for biodiesel by importers, and 21.55 million generated for nonester renewable diesel by importers. 

Nearly 17.57 million D5 advanced biofuel RINs were generated in June, including 10.51 million generated for naphtha by domestic producers, 5.24 million generated for ethanol by domestic producers, 1.5 million generated for nonester renewable diesel by domestic producers, 199,469 generated for LPG by domestic producers, 134,096 generated for RNG by domestic producers, and 119,290 generated for renewable heating oil by domestic producers. 

Total D5 RIN generation for the first six months of this year reached 132.5 million, up 37% when compared to the first half of last year. That volume includes 70.48 million generated for naphtha by domestic producers, 37.34 million generated for nonester renewable diesel by domestic producers, 22.52 million generated for ethanol by domestic producers, 1.44 million generated for renewable heating oil by domestic producers, 364,133 generated for LPG by domestic producers, 221,664 generated for compressed RNG by domestic producers, 

Nearly 1.25 billion D6 renewable fuel RINs were generated in June, nearly all for ethanol by domestic producers, with approximately 1.25 million generated for ethanol by importers. 

Total D6 RIN generation for the first half of 2025 reached 7.21 billion, down 1% when compared to the same period of 2024. That volume includes 7.2 billion generated for ethanol by domestic producers, 6.49 million generated for ethanol by importers, and 153,911 generated for biodiesel by domestic producers.

According to the EPA, 18,071 D7 cellulosic diesel RINs were generated in June, all for cellulosic heating oil by importers. A total of 147,211 D7 RINs were generated during the first half of this year, all for cellulosic heating oil by importers. When compared to the first half of last year, D7 RIN generation was down 23%.
