International Day for the Preservation of the Ozone Layer, 16 September 2014

Tonga prepares to join its counterparts  around  the  globe  in observing  International Day for the Preservation of  the Ozone Layer tomorrow,  under  the theme: "Ozone Layer Protection: The Mission Goes On", it  does so  reassured  in the knowledge  that  the Ozone Layer is "certainly recovering" .

The Montreal Protocol on Substances that Deplete the Ozone Layer is widely recognized as one of the most successful environmental treaties in history. It establishes legally binding controls on the national production and consumption of ozone-depleting substances, and enjoys universal ratification by 197 parties.

Recent scientific findings reveal the importance of the Montreal Protocol. Without the Protocol and associated agreements, atmospheric levels of ozone-depleting substances could have increased ten-fold by 2050. Concerted action has prevented millions of cases of skin cancer.

The Protocol has also significantly contributed to the fight against climate change, as many ozone-depleting substances are powerful greenhouse gases. Climate change is affecting communities, economies and ecosystems across the globe. It is essential that we act to mitigate the threat with the same unity of purpose as we have in facing the dangers of ozone depletion.

Though the abundance of ozone-depleting substances in the atmosphere is declining and the ozone layer is expected to recover around the middle of this century. There are, however, some remaining challenges to the phase-out of ozone-depleting substances. This year’s theme seeks to galvanize all stakeholders to increase their efforts to address the challenges.

The Ozone Depleting Substances Project will host a talkback program on Radio Tonga One on the16th of September 2014 at 2:00pm to raise public awareness on the importance of the ozone layer and the work of the Montreal Protocol.
