Last January, the United Nations Scientific Assessment Panel of the Montreal Protocol revealed in a UN report that the hole in the ozone layer is closing and predicts recovery within the next four decades.

The Montreal Protocol was signed in 1987 and entered into force in 1989. Its main mission is to provide for the ozone layer by reducing the use of harmful chemicals, the ODS (Ozone Depleting Substances).
Despite this recovery, there is no certainty of its continuity in the future and what the impact will be on climate change mitigation.
We should remember the goal of reducing the temperature increase limit by 1.5º celsius, stipulated in the Paris Agreement, approved in 2015 during COP21. It is increasingly urgent that we take an active part in the change of mentality necessary to combat climate change.
