The National Highway Transportation Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) have proposed a new reading of the Energy Policy and Conservation Act of 1975 (EPCA) that governs federal fuel economy standards. The regulations would relax federal greenhouse gas tailpipe standards and fuel economy standards, and preempt emissions standards put in place by California and adopted by other states.
