History

Historical Context

The Clean Air Act, initially enacted in 1963 and significantly amended in 1970, established the EPA to regulate air pollution and protect public health. By 2019, the Act contributed to a 73% reduction in six common pollutants. Current legal challenges, such as the one led by New York Attorney General Letitia James, reflect ongoing tensions over environmental regulations and their enforcement at the state level.
