The results of this analysis of the costs and benefits of the Clean Air Act are stunning. “Benefits and Costs of the Clean Air Act: Second Prospective Study—1990-2020” claims that by 2020, benefits are estimated to fall in the $2 trillion range, with costs amounting to a mere $65 billion. The vast majority of the benefits will be seen in the lives saved by the law, which amount to an estimated 230,000 prevented early deaths.
