Lecture 12 - Air Quality Law: Margins of Safety

The lecture describes the Clean Air Act and the way the federal government measures air quality as well as improvements in air quality. Professor Wargo reviews challenges in regulating air quality, reasons for lack of adequate enforcement, and approaches to setting ambient air quality standards. The lecture focuses predominantly on vehicle emissions, and the difficulty that regulators face when trying to decrease particulate matter expelled by cars. The public health impacts of poor air quality, particularly in urban areas, are discussed as well. **Reading assignment:** Wargo, //Green Intelligence//, chapters 13-15 Weinberg, //Understanding Environmental Law//, pp. 75-102 **Resources** ;[[http://oyc.yale.edu/sites/default/files/evst255_12_13%20LecAir1Feb23_25c.pdf|Lecture 12 [PDF] ]]
