16 September: International Day for the Preservation of the Ozone Layer
The International Day for the Preservation of the Ozone Layer was observed globally on 16 September 2017 with the theme 'Caring for all life under the sun'.
The Day commemorates the date of the signing of the 'Montreal Protocol on Substances that Deplete the Ozone Layer'. This year marks the 30th anniversary of the Montreal Protocol.

In 1994, the United Nations General Assembly proclaimed 16 September as the International Day for the Preservation of the Ozone Layer to commemorate the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer that was signed in 1987.
On 16 September 2009, the Montreal Protocol along with Vienna Convention became the first treaty in the history of the United Nations to achieve Universal Ratification.
About Montreal Protocol
• The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it.
• The Protocol is structured around several groups of ozone-depleting substances. The groups of chemicals are classified according to the chemical family.
• It requires the control of nearly 100 chemicals in several categories. For each group of chemicals, the Treaty sets out a timetable for the phase-out of production and consumption of those substances.
• The timetable set by the Montreal Protocol applies to consumption of ozone depleting substances.
• Implementation of the Montreal Protocol progressed well in developed and developing countries.
