Renewable Identification Numbers (RINs) were developed to act as tracking mechanisms that ensure compliance with the U.S. biofuel use mandates legislated in 2005 and increased and adjusted to include sub-mandates in 2007. Reviewing the rules for RIN production and use, we conclude that RIN...

US biofuel policy includes greenhouse gas reduction targets. Regulators do not address the potential that biofuel policy can have indirect impacts on greenhouse gases through its impacts on petroleum product markets, and scientific research only partially addresses this question. We use economic...

Biofuel policy in the United States sets minimum use mandates for different biofuels, but the cellulosic mandate, introduced in 2010 has been waived and reduced to nearly zero since then. This waiver has shifted the burden of compliance to other biofuels, but other options exist. We examine some...

US energy policy mandates minimum levels of biofuel use. The four interdependent mandates of the 2007 legislation - EISA - are defined by their feedstocks and greenhouse gas reduction targets, and are each set to rise over the coming years. If the volumes of use would be below the mandated...

Here, we explore the interaction of market volatility and the scope for policy to affect this interaction, with a focus on how corn yields and petroleum prices affect...
