Air Pollution Cost-Benefit Rule

The rule will do significant harm by minimizing the non-monetary benefits of air-quality protections, such as reductions in mortality and chronic illness.

Case Overview

A eleventh-hour Trump administration rule undermines the Environmental Protection Agency’s ability to protect air quality and public health.

Under the regulation, the EPA will be required to prepare an extensive cost-benefit analysis before proposing any significant protections under the Clean Air Act — even when Congress has prohibited the EPA from considering costs.

The regulation poses a particular threat to low-income communities, whose health and well-being will be further marginalized as a result of the rule’s requirements.

On its first day in office, the Biden administration announced that the cost-benefit rule is one of the many Trump administration policies that are currently under review.
