CAFE Standards: What’s Biomass Got to Do with It?

On July 18, the Environmental Protection Agency (EPA), the National Highway Traffic Safety Administration (NHTSA) and the California Air Resources Board (CARB) released their Draft Technical Assessment Report (TAR), providing a midterm evaluation of the Corporate Average Fuel Economy (CAFE) standards for passenger vehicles through 2025. As the deadline for providing comments to EPA approaches, we take a look at the often overlooked role that biofuels can play in improving fuel efficiency.

Many more efficient engines require higher octane fuels. The rise in engine efficiency has led auto manufacturers to recommend premium gasoline in an increasing number of new cars, due to the need forhigher octane content. But higher blends of biofuels, like ethanol, can provide the same octane benefits. This relationship is not addressed in EPA’s Draft TAR, and is something that EESI intends to recommend in our submitted comments.
