Book cover

International Day for the Preservation of the Ozone Layer, 16 September, as designated by the United Nations General Assembly, commemorates the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer that protects Earth against the harmful effects of ultraviolet radiation.

Marco Gonzalez, Stephen O. Andersen, and Sally Rand, with the United Nations Environment Programme’s Ozone Secretariat, will release a new book celebrating the 35th Anniversary of the Montreal Protocol. The book highlights successes and documents innovation during the first 35 years and inspires new ambition to strengthen protection of stratospheric ozone and climate before Earth passes tipping points.

The book tells the story of the Montreal Protocol, revealing a model of cooperation, collaboration, universal ratification, record of compliance with over 99 per cent of controlled ozone-depleting substances (ODSs) phased out, the ozone layer on the path to recovery, the 2007 Montreal Adjustment, and the 2016 Kigali Amendment moving the Montreal Protocol further into environmental protection.

Unfinished business includes: HCFC phase out, ODS bank management, HFC phase down, uncontrolled ozone-depleting greenhouse gas nitrous oxide (N2O), feedstock exemptions for plastics production, and dumping of obsolete cooling appliances.

The book is anticipated to be released at 34th Meeting of the Parties to the Montreal Protocol on 31 October 2022
