The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet.
On 19 December 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date, in 1987, on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed.
States are invited to devote the Day each year to promote, at the national level, activities in accordance with the objectives of the Montreal Protocol and its amendments.
This year marks the 30th anniversary of the Montreal Protocol. As part of the anniversary celebrations, the Ozone Secretariat will launch a communication campaign ahead of World Ozone Day to be marked on 16 September 2017.
The #OzoneHeroes campaign to be launched on 14 September will seek to celebrate the major 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 its new mandate to phase down climate-warming hydrofluorocarbons under the Kigali Amendment, adopted in 2016.
Campaign materials and further information on how everyone can participate in celebrating this important milestone will be available from 14 September at www.ozoneheroes.org.
