In a bid to spread awareness of the depletion of ozone layer and search for a solution to preserve it,' World Ozone Day' is being celebrated all over the World.
Every year on September 16, the World celebrates the International day for the preservation of Ozone layer as the World Ozone Day. The ozone layer is located roughly 15 to 35 km above the Earth's surface and contains a high concentration of ozone molecules. The theme of this year is “Caring for all life under Sun”.
In 1994, the United Nations General Assembly proclaimed 16th September as International Day for the preservation of the Ozone layer to commemorate the day of signing 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 United Nations to achieve Universal Ratification.
During the United Nations convention in Vienna for the Montreal Protocol, the General Assembly declared September 16 as the World Ozone day in order to remind the world of the depleting ozone layer. The principle aim of the Montreal Protocol is to protect the Ozone layer by taking the 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. To stop the depletion of Ozone layer requires the control of 100 chemicals in several categories.
For each of group of chemicals, the treaty sets out a timetable for the phase-out of production and consumption of those substances. The timetable set by Montreal Protocol applies to consumption of Ozone depleting substances. Implementation of the Montreal Protocol progressed well in developed and developing countries.
After the Montreal Protocol signing, over 190 countries acted on the use of chlorofluorocarbon (CFC) and banned it. Compared to other gases, ozone is quite rare. But, it does an important job by protecting the earth from Sun's harmful rays.In a nutshell,
it acts as Earth's sunscreen, as it absorbs some of the sun's radiation hitting our planet. This year marks 30th anniversary of Montreal Protocol. As a part of it, the Ozone Secretariat launched the communication campaign “Ozone Heroes” and it once again reminds us of our responsibility to preserve and protect it.
