Renewable Identification Number (RIN) for biofuels created by the EPA as a unit of compliance to assist with the implementation of the Renewable Fuel Standard (RFS), which currently sets annual mandates on renewable transportation fuels through 2022. This report was created to facilitate an understanding of the RIN market, which is heavily tied to understanding the effects of RFS mandates on the biofuel and feedstock markets. This report discusses the details of the RIN system and its role in the implementation of the current RFS2, and examines supply, use, prices, and trade for biofuels and biofuel feedstocks both domestically and prospectively in major producing, importing, and exporting countries. Additionally, the report examines historical data and USDA baseline projections in order to generate projections of the biofuel and feedstock markets. The report primarily focuses on ethanol and corn, biodiesel and soybeans. It also contains information on other biofuel feedstocks and second-generation biofuels such as cellulosic and biofuel co-products such as distiller's grains.
