Highlights

 

Concerns over national security, environmental stresses, and economic pressures from increased fuel prices have led to the nation's interest in reducing oil consumption. Efforts to reduce oil consumption will need to include the transportation sector. For example, several Members of Congress have introduced bills proposing changes to the corporate average fuel economy (CAFE) program. This program includes mile per gallon standards for light trucks and cars that manufacturers must meet for vehicles sold in this country. This testimony is based on ongoing work for this committee. This testimony describes (1) recent and proposed changes to CAFE standards; (2) observations about the recent changes, the existing CAFE program, and NHTSA's (National Highway Traffic Safety Administration) capabilities to further restructure CAFE standards; and (3) initial observations about how the CAFE program fits in the context of other approaches to reduce oil consumption. To address these issues, we reviewed program legislation, rule makings, and operational documents. Also, we interviewed officials from NHTSA, the Department of Energy, Environmental Protection Agency, the auto industry, labor unions, and the insurance industry. Finally, we contacted several recognized experts in fuel economy and safety. Our report will be issued in July 2007.
