The United Nations International Day for the Preservation of the Ozone Layer is celebrated each year around the world on September 16, a date that marks the 1987 signing of the Montreal Protocol.
This international treaty was enacted to protect the ozone layer by eliminating the use of ozone-depleting substances and has led to the phase-out of 99 per cent of ozone-depleting chemicals in refrigerators, air-conditioners and many other products. These efforts have provided protection for the ozone layer and in doing so, helped to improve human and ecosystem health by limiting incoming harmful UV radiation. The phasing out of HFC’s and CFC’s has also contributed significantly to combating climate change by reducing the atmospheric concentration of these known contributors to global warming.
This year’s theme, “The Montreal Protocol: fixing the ozone layer and reducing climate change”, recognizes the recent finding by the Assessment Panel to the Protocol that ozone recovery is on track and the resulting health and climate impacts are significant.
To help celebrate this important occasion, primary and secondary school educators throughout the world are encouraged to organize classroom activities that focus on topics related to ozone, the ozone layer and the connection between ozone action and climate change.
