Vehicle Fuel Economy: Reforming Fuel Economy Standards Could Help Reduce Oil Consumption by Cars and Light Trucks, and Other Options Could Complement These Standards

A letter report issued by the Government Accountability Office with an abstract that begins "Concerns over national security, environmental stresses, and high fuel prices have raised interest in reducing oil consumption. Through the Corporate Average Fuel Economy (CAFE) program, the National Highway Traffic Safety Administration (NHTSA) requires cars and light trucks to meet certain fuel economy standards. As requested, GAO discusses (1) how CAFE standards are designed to reduce fuel consumption, (2) strengths and weaknesses of the CAFE program and NHTSA's capabilities, and (3) market-based policies that could complement or replace CAFE. To do this work, GAO reviewed recent studies and interviewed leading experts and agency officials.
