Press Release: The International Ozone Commission, on the 35th anniversary of the Montreal Protocol, reports new milestones in documenting ozone layer recovery
September 16th is the International Day for the Preservation of the Ozone Layer, celebrating the 35th signing anniversary of the 1987 Montreal Protocol treaty on Substances that Deplete the Ozone Layer. We would like to report success in the reduction of the ozone-depleting substances (ODSs) in the stratosphere by about 25 % since their peak in the late 1990s, which sets the ozone layer on the path of recovery by 2060.
