The Crucial Role of Cost-Benefit Analysis in Environmental Policy

As an expert in environmental policy, I have witnessed firsthand the impact of the Clean Air Act and the ongoing debate surrounding its cost-benefit analysis. The Environmental Protection Agency (EPA) has long been prohibited from considering costs when setting national air quality standards, but recent court rulings have brought this issue to the forefront. While some argue that cost-benefit analysis is a necessary tool for making regulatory decisions, others believe it should not apply to all aspects of life. As someone who has studied and worked in this field for many years, I strongly believe that cost-benefit analysis is a crucial aspect of environmental policy that should not be overlooked. One of the main arguments against cost-benefit analysis is that it goes against the intent of the Clean Air Act.

However, as the Court's ruling in American Trucking v. EPA showed, the focus is not on the wisdom of cost-benefit analysis, but rather on the textual intent of the law. This means that while cost considerations may not be the primary factor in setting air quality standards, they should still be taken into account. Janet Yellen, a professor of economics at the University of California at Berkeley and former president of the Council of Economic Advisors, has also spoken out in support of cost-benefit analysis. In her opinion, it is a valuable tool for making reasonable regulatory judgments and should be considered as part of the economy and public policy.

I wholeheartedly agree with her stance on this issue. Cost-benefit analysis is a fundamental aspect of conventional economics, but it is clear that many Americans are not convinced that it should apply to all spheres of life. This is evident in the current administration, where John Graham, former director of the Center for Risk Analysis at Harvard, was appointed by President Bush to head the Office of Information and Regulatory Affairs (OIRA). Graham was one of the signers of the amici brief published in American Trucking, showing his support for cost-benefit analysis in environmental policy. In 1999, the District of Columbia Court of Appeals ruled that the Clean Air Act, as interpreted by the EPA, did not provide any intelligible principle for establishing air quality standards at one time and not another. This ruling stemmed from a 1993 lawsuit brought by the American Lung Association (ALA), which claimed that the EPA had failed in its legal responsibility to review the National Ambient Air Quality Standards (NAAQS) every five years.

This case highlights the importance of considering both costs and benefits when making decisions about air quality standards. One of the main benefits of implementing emission control programs is the significant improvement in health and air quality. These programs have already had a positive impact, and their benefits will only continue to increase over time. When calculating the potential benefits of a policy, surveys are often used to determine people's willingness to pay for things like better views or improved health. This type of analysis is explicitly supported by the use of cost-benefit analysis in federal and state agencies when developing air pollution control programs. It is clear that cost-benefit analysis is an essential aspect of environmental policy, but it is not without its challenges.

The current practice is complex and often leads to inaccurate results. In fact, during the Clinton administration, detailed guidelines were published to help agencies improve their analysis of costs and benefits when implementing major regulations. Despite these efforts, there are still obstacles to achieving accurate cost-benefit analysis. Legal advocates for cost-benefit analysis in regulatory policy include Richard Posner, former chief judge of the Seventh Circuit Court of Appeals, and Cass Sunstein, a law professor at the University of Chicago. However, it is unlikely that Congress will open the debate on this issue, at least in the context of the Clean Air Act.

As an expert in this field, I believe that cost-benefit analysis should continue to be an essential tool in environmental policy, and efforts should be made to improve its accuracy and effectiveness.
