2015 Theme: 30 Years of Healing the Ozone Together - "Ozone: All there is between you and UV.”

                                               International Day for the Preservation of the Ozone Layer

This year marks the 30th anniversary of the Vienna Convention for the Protection of the Ozone Layer, an important milestone in the protection of the ozone layer. The theme for the celebration of the anniversary and this year’s International Day for the Preservation of the Ozone Layer to be marked on 16 September is, “30 years of healing the ozone together.” The theme is supported by the slogan, “Ozone: All there is between you and UV.”

"As we look forward to the adoption of the 2030 Agenda for Sustainable Development, and the effort by governments later this year in Paris to forge a new, collective path forward on climate change, the Montreal Protocol’s success should inspire us. It shows what we are capable of when nations act together on a global challenge."

Background

In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).

States were invited to devote the Day to promote activities in accordance with the objectives of the Protocol and its amendments. 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.

The phaseout of controlled uses of ozone depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations, but have also contributed significantly to global efforts to address climate change; furthermore, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching the earth.
