Ozone Layer Protection
The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer. But through domestic and international action, the ozone layer is healing and should fully recover by about 2065. This website addresses stratospheric ozone issues, including the science of ozone depletion, EPA's regulatory approach to protecting the ozone layer, EPA-approved alternatives to ozone-depleting substances, and sun safety.
