Total D5 RIN generation for the first three quarters of the year reached 158.34 million. That volume includes 73.15 million generated for nonester renewable diesel by domestic producers, 59.11 million generated for naphtha by domestic producers, 21.07 million generated for ethanol by domestic producers, 3.32 million generated for renewable heating oil by domestic producers, 991,034 generated for LPG by domestic producers, and 707,003 generated for compressed RNG by domestic producers.

More than 1.21 billion D6 renewable fuel RINs were generated in September, nearly all for ethanol by domestic producers. Approximately 1.17 million D6 RINs were generated for ethanol by importers and 378,922 were generated for biodiesel by domestic producers. 

Total D6 RIN generation for the first nine months of 2024 reached 11.14 billion. That volume includes 11.1 billion generated for ethanol by domestic producers, 12.72 million generated for biodiesel by domestic producers, 10.78 million generated for ethanol by importers, 9.35 million generated for biodiesel by importers, 3.93 million generated for renewable gasoline by domestic producers, 250,191 million generated for nonester renewable diesel by domestic producers, and 64,809 generated for renewable jet fuel by domestic producers.

According to the EPA, 23,774 D7 cellulosic diesel RINs were generated in September, all for cellulosic heating oil by importers. Total D7 RIN generation for the first nine months of 2024 reached 227,964, all of which were generated for cellulosic heating oil by importers.
