On September 16, we celebrate International Day for the Preservation of the Ozone Layer! This day was created in 1994 to recognize and commemorate the date that the Montreal Protocol on Substances that Deplete the Ozone Layer came into force. Since then, this international agreement has been a major success in protecting our planet's ozone layer. We can be proud of what has been accomplished thanks to collective global action, and use this day as an opportunity to continue advocating for more protection of the ozone layer.
