Which aspect of environmental governance does the CAA specifically address?

The Clean Air Act (CAA) specifically focuses on air quality control, making it a critical piece of legislation aimed at managing and reducing air pollution. The act establishes the regulatory framework for setting air quality standards, controlling emissions from both stationary and mobile sources, and outlining states' responsibilities in implementing measures to protect air quality. By targeting pollutants that adversely affect human health and the environment, the CAA aims to ensure clean and safe air for the public.

In contrast, the other areas mentioned—waste management, water pollution prevention, and land use management—are addressed by different environmental laws and regulations. For instance, waste management is typically governed by the Resource Conservation and Recovery Act (RCRA), while the Clean Water Act focuses on water quality and pollution prevention. Land use management is often a matter of local zoning laws and regulations, influenced by various federal and state policies but not exclusively covered under the CAA.
