As part of its responsibility to protect the environment and human health, EPA promotes and helps to implement methods of controlling air pollution. These control methods include voluntary and enforced reduction in the use of ozone-depleting substances, phasing out the use of certain toxic chemicals, developing treatment methods for polluted areas, and the creation of cleaner alternatives. The Agency enacts these various controls through targeted grants, in cooperation with state and local governments, in partnership with industry, and through the enforcement of environmental regulations.
