The Benefits and Costs of the Clean Air Act, 1990 to 2010 - First Prospective Study

On November 15, 1999, EPA issued the second in this series of reports, "The Benefits and Costs of the Clean Air Act, 1990 to 2010." This second study, the first of an ongoing series of prospective analyses, was also issued after a six-year process of study development and outside expert review. This first prospective study also finds that the benefits of the programs and standards required by the 1990 Clean Air Act Amendments significantly exceed costs.

The report includes an Executive Summary which describes the study and its findings in more detail and nine technical appendices which provide in-depth documentation for each of the analytical components.

The Science Advisory Board final recommendations to EPA are also available.
