The Clean Air Act (CAA) is a United States federal law enacted in 1970 that regulates air emissions from stationary and mobile sources. The Environmental Protection Agency (EPA) is responsible for implementing the CAA and has the authority to set and enforce national standards for air quality. The term ECOLAW is an acronym for environmental law, which is a body of laws that regulate human activities that have an impact on the environment. The Clean Air Act is an example of environmental law, as it sets standards for air quality and regulates emissions from sources that could potentially harm the environment.
