Clean Air Act Overview

Benefits and Costs of the Clean Air Act 1990-2020. Report Documents and Graphics

In March 2011, EPA issued the Second Prospective Report which looked at the results of the Clean Air Act from 1990 to 2020. According to this study, the central benefits estimate exceeds costs by a factor of more than 30 to one. The report was updated in April 2011.

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.
