International Day for the Preservation of the Ozone Layer

September 16, 2020

The International Day for the Preservation of the Ozone Layer, commemorated on September 16th, celebrates the Vienna Convention for the Protection of the Ozone Layer and the subsequent Montreal Protocol. Under this international agreement, governments from all over the world, scientists and industry came together and agreed to work in unison to eliminate the ozone depleting substances known as CFCs. Thanks to this Protocol, the Earth´s ozone layer is starting to recover.

Dr. Mario Molina feels immense pride for being an instrumental player in these negotiations, for it was him and his professor, Frank Sherwood Rowland who first discovered and pointed to CFCs as the substances responsible for the depletion of the ozone layer, earning them the 1995 Nobel Prize in Chemistry.

“The research that we completed with respect to the thinning of the ozone later in the stratosphere culminated in the Montreal Protocol. This international agreement was a great success: all the nations of the world agreed to confront this problem together, and to stop producing industrial compounds that were affecting the ozone layer. A formidable example, because the industries also ended up winning, as they started to produce alternative substances that reduced the harm instigated on the environment, with practically no significant economic losses. It has been proven that the Protocol has had an enormous impact, and that the ozone layer is recovering.

Furthermore, it is a clear testament of how society, government, academia, industry, and civil organizations can work together and come to a consensus in favor of our planet.”
