World Ozone Day 2024 Campaign Video (EN)

The Montreal Protocol is rightly hailed as a multilateralism success story. It united the world to phase out ozone-depleting substances putting the ozone layer on the path to recovery and protecting all life on Earth. On this World Ozone Day, we also celebrate its climate action. Phasing out ozone-depleting substances has proven to be a powerful tool for climate action that has helped slow global warming, for example, postponing the first ice-free Arctic summer by up to 15 years.
