The Clean Air Act is a comprehensive federal law that regulates air emissions from stationary and mobile sources. It aims to protect public health and the environment by establishing national ambient air quality standards. Under this act, states are required to develop and enforce regulations that limit air pollution, set standards for air clarity, and improve air quality over time. The act has been instrumental in reducing pollutants and preventing environmental degradation, highlighting the states' commitment to future air quality.

In contrast, the Clean Water Act primarily focuses on regulating water pollution, while the Air Quality Improvement Program and the Environmental Protection Initiative may include air quality measures but do not have the same broad federal foundation and enforcement mechanisms as the Clean Air Act. Therefore, the Clean Air Act stands out as the key initiative directly aimed at maintaining and improving air quality going forward.
