Some of EPA's top priorities are to improve air quality, take action on climate change, and clean up our communities. EPA's work on these priorities falls under the Clean Air Act and includes developing national programs, technical policies and regulations for controlling air pollution and radiation exposure. These efforts help protect the health of all Americans by preventing pollution and increasing energy efficiency, improving indoor and outdoor air quality, reducing industrial air pollution and pollution from vehicles and engines, protecting the stratospheric ozone layer, reducing acid rain, and addressing climate change.
EPA is celebrating the 40th anniversary of the Clean Air Act. Learn more about how this landmark law has protected America's health and environment.
