This bill would end government rules that set car and truck emission or fuel economy limits. It repeals the Clean Air Act section that requires tailpipe standards and wipes out the federal fuel economy program, and it blocks states from setting or enforcing their own vehicle emission rules, including rules issued under special waivers. It also says neither the federal government nor any state may create, enforce, or keep fuel emission standards going forward, and it nullifies any such rules already in place. The bill states that these steps are meant to cut costs for families and manufacturers by removing overlapping and changing regulations.
