The Clean Air Act (CAA)

The Clean Air Act (CAA) is a U.S. law that aims to protect air quality by regulating emissions from industries, vehicles, and other sources. It sets standards for harmful pollutants like smog, soot, and greenhouse gases, helping reduce air pollution and protect public health and the environment. Environmental agencies monitor air quality to ensure these standards are met and take action when pollution levels are too high. Overall, the CAA promotes cleaner air for everyone, balancing economic growth with health and environmental sustainability.
