Environmental Protection Agency: Basic Ozone Layer Science
Environmental Protection Agency

The Earth’s ozone layer protects all life from the sun’s harmful radiation, but human activities have damaged this shield.

Environmental Protection Agency: Health and Environmental Effects of Ozone Layer Depletion
Environmental Protection Agency

Reduced ozone levels as a result of ozone depletion mean less protection from the sun’s rays and more exposure to UVB radiation at the Earth’s surface.

Environmental Protection Agency

The Atmospheric and Health Effects Framework (AHEF) model is used by the EPA to evaluate human health effects associated with a depleted stratospheric ozone layer.

Environmental Protection Agency: Addressing Ozone Layer Depletion
Environmental Protection Agency

As part of the United States’ commitment to implementing the Montreal Protocol on Substances that Deplete the Ozone Layer, Congress amended the Clean Air Act to add provisions (under Title VI) for protecting the ozone layer.

Environmental Protection Agency: Methyl Bromide
Environmental Protection Agency

In the atmosphere, methyl bromide depletes the ozone layer and allows increased ultraviolet radiation to reach the earth’s surface.

Environmental Protection Agency: Phaseout of Ozone-Depleting Substances (ODS)
Environmental Protection Agency

New production and import of most HCFCs were phased out as of 2020.
