D6 RIN Generation

D6 RINs known as the ‘Conventional’ category is nearly 100% corn based ethanol. Fuels with the lowest GHG emissions reduction vs petroleum fuels are put into this category. And RIN generation within this space has been stagnant relative to gasoline seasonality in the 1.1-1.3 billion RIN range due to most the of gasoline in the US being blended with 10% ethanol from corn. (1 ethanol gallon = 1 RIN)
