Moe than 1.12 billion D6 renewable fuel RINs were generated in February, nearly all for ethanol by domestic producers. Approximately 1.04 million D6 RINs were generated for ethanol by importers and 153,911 were generated for biodiesel by domestic producers. When compared to February 2024, D6 RIN generation was down 7%.

Total D6 RIN generation for the first two months of 2025 reached 2.37 billion. That volume includes 2.36 billion generated for ethanol by domestic producers, 2.31 million generated for ethanol by importers, and 153,911 generated for biodiesel by domestic producers. 

No D7 cellulosic diesel RINs were generated in February. Total D7 RIN generation for the first two months of the year reached 28,782, all of which were generated for cellulosic heating oil by importers.
