International Days' Sentiment

In 1987 representatives from 24 countries met in Montreal and announced to the world that it was time to stop destroying the ozone layer. In so doing, these countries committed themselves, via the Montreal Protocol on Substances that Deplete the Ozone Layer, to rid the world of substances that threaten the ozone layer.
On December 19, 1994, the UN General Assembly proclaimed September 16 to be the International Day for the Preservation of the Ozone Layer, commemorating the date when the Montreal Protocol on Substances that Deplete the Ozone Layer was signed in 1987. The day was first celebrated on September 16, 1995.

What do people do?

On this day primary and secondary school educators throughout the world organize classroom activities that focus on topics related to the ozone layer, climate change and ozone depletion. Some teachers use educational packages from the UN Environment Programme (UNEP) that have been specifically tailored to address topics about the earth's ozone layer. Other activities that are organized by different community groups, individuals, schools and local organizations across the world include: the promotion of ozone friendly products; special programs and events on saving the ozone layer; the distribution of the UNEP's public awareness posters to be used for events centered on the International Day for the Preservation of the Ozone Layer; and the distribution of awards to those who worked hard to protect the earth's ozone layer.
