International Day for the Preservation of the Ozone Layer

The International Day for the Preservation of the Ozone Layer marks the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer. In 2017, the #OzoneHeroes campaign will be launched on 14 September to celebrate the accomplishments of the Montreal Protocol in protecting the ozone layer and the climate, to increase public recognition of the success and impact of the Protocol, and to generate further support for the Protocol and the Kigali Amendment, which phases down climate-warming hydrofluorocarbons and was adopted in 2016.
