The EPA issues RINs to track renewable fuel usage throughout the supply chain. Refiners, importers and blenders -- called obligated parties -- use them to show the EPA that they have fulfilled their mandated government use of renewable fuels. If the obligated party has not used enough physical product, it can buy RINs to satisfy the quota.
