World Ozone Day 2019 : le trou de la couche d'ozone diminue

Le 16 septembre, c’est la Journée internationale de la protection de la couche d’ozone. Une couche dont le trou a été en partie résorbé, grâce à la mobilisation internationale.

32 ans et en voie de guérison :

The theme for the World Ozone Day 2019, to be marked on 16 September, is : 32 Years and Healing

The theme for this year celebrates over three decades of remarkable international cooperation to protect the ozone layer and the climate under the Montreal Protocol. It reminds us that we must keep up the momentum to ensure healthy people and a healthy planet.

The Montreal Protocol has led to the phase-out of 99 per cent of ozone-depleting chemicals in refrigerators, air-conditioners and many other products.

The ozone hole is expected to gradually close, with ozone returning to 1980 values by the 2060s.
