CAFE Standards and Fuel Efficiency
Vehicles in the United States are regulated under policies—such as the Corporate Average Fuel Economy (CAFE) standards—that require manufacturers to reduce fuel consumption and carbon emissions. RFF researchers are analyzing the effectiveness of these policies compared to those that influence fuel prices.

RFF analysis shows that relying on a vehicle’s lifetime miles traveled, rather than a class average, would reduce the costs of achieving greenhouse gas standards.
