Renewable Identification Numbers (RINs)
According to the definition in the title 40 of the Code of Federal Regulation, part 80 (40 CFR, part 80), a renewable identification number (RIN) is a unique number generated to represent a volume of renewable fuel produced or imported that qualifies under the Renewable Fuel Standard (RFS) program. Generated RIN is a proof that renewable fuel:
    •qualifies for the “D code”
    •is produced from renewable biomass
    •is produced according to the registration requirements, reporting requirements and record-keeping requirements
    •is designated for use as transportation fuel, heating oil or jet fuel.
RINs are given equivalence values for each gallon of renewable fuel depending of its type:
    •ethanol - 1.0 equivalence value
    •biodiesel (ester) - 1.5 equivalence value
    •butano
