Authorizes a State to enforce its laws or regulations on disclosure of air pollutant emissions for an automobile only if such law or regulation is identical to the Federal disclosure requirements on such emissions.

Directs the Administrator of the Environmental Protection Agency to calculate, provide to the manufacturer, and publish for each model of automobile and for each model year an air pollutant emissions index number representing the composite level of emissions for such automobile.

Provides a waiver to States with respect to Federal pollutant emission disclosure requirements.
