Directs the Administrator to study the effects of emission of sulfur bearing compounds from motor vehicles and aircraft.

Extends the exception for disclosure of confidential information in administrative and judicial proceedings to emission data upon a satisfactory showing to the Administrator that such data would divulge trade secrets.

Requires that documentation, justifications, proposed drafts, and comments of other agencies on proposed motor vehicle emission standards be made available to the public once such standards are proposes. Establishes procedures for oral presentation of views with opportunity for cross-examination, with respect to such standards. Authorizes direct review of alleged procedural errors in the appropriate court of appeals.

Authorizes the appropriation of $200,000,000 per fiscal year for fiscal years 1978, 1979, and 1980, to carry out the purposes of this Act other than research, development, and demonstration activities
