"For over three decades, the Montreal Protocol has done much more than shrink the ozone hole; it has shown us how environmental governance can respond to science, and how countries can come together to address a shared vulnerability. I call for that same spirit of common cause and, especially, greater leadership as we strive to implement the Paris Agreement on climate change and mobilize the ambitious climate action we so urgently need at this time."

UN Secretary-General António Guterres

The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet.

The phaseout of controlled uses of ozone depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations, but have also contributed significantly to global efforts to address climate change; furthermore, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching the earth.

Keep Cool and Carry On: The Montreal Protocol

The theme for World Ozone Day 2018 is a motivational rallying call urging all of us to carry on with the exemplary work of protecting the ozone layer and the climate under the Montreal Protocol. The theme has two connotations – that our work of protecting the ozone layer also protects climate and that the Montreal Protocol is a “cool” treaty, as exemplified by its outstanding success.

What You Can Do:

  • Protect yourself from ozone layer depletion by avoiding excessive sun exposure.
  • Take care of your appliances to minimize ozone layer impact.
