What is the purpose of the Clean Air Act?

The purpose of the Clean Air Act is to regulate air emissions and protect air quality. This legislation was enacted to address issues related to air pollution, setting national air quality standards for harmful pollutants that can affect public health and the environment. The Clean Air Act empowers the Environmental Protection Agency (EPA) to establish limits on emissions from both stationary sources, like factories and power plants, as well as mobile sources, such as cars and trucks.

By focusing on air quality, the Clean Air Act serves as a critical tool to ensure that the air we breathe is safe and healthy. This involves not only regulating emissions but also taking measures to monitor air quality, encouraging technological innovations to reduce pollution, and improving overall air standards to protect vulnerable populations. The other options, while important environmental issues, do not relate directly to the Clean Air Act's primary focus on air pollution and air quality regulation.
