For several years now, no single topic has caused more angst in refiners’ quarterly earnings calls than the seemingly arcane topic of renewable identification numbers, or RINs, which can have a big impact on a refiner’s financial performance. RINs are a feature of the federal Renewable Fuel Standard (RFS), which requires renewable fuels like ethanol and bio-based diesel to be blended into fuels sold in the U.S. And depending on your point of view — farmer, refiner, blender, consumer, politician — you may have a very different perspective regarding RINs’ role as a tax and a subsidy. In today’s RBN blog, we dig into the fundamental aspects of RINs at the root of this long-running controversy and examine the role of RINs as a mechanism for forcing renewables into fuels.
