Congressional Budget Office. "Fuel Economy Standards Versus a Gasoline Tax". March 9, 2004 - "This issue brief focuses on the economic costs of CAFE standards and compares them with the costs of a gasoline tax that would reduce gasoline consumption by the same amount. The Congressional Budget Office (CBO) estimates that a 10 percent reduction in gasoline consumption could be achieved at a lower cost by an increase in the gasoline tax than by an increase in CAFE standards."
