“The Montreal Protocol is one of the most important and successful global environmental treaties ever,” said David Fahey, director of NOAA's Chemical Sciences Laboratory and Co-chair of the Scientific Assessment Panel of the Montreal Protocol.
Universal ratification of the Montreal Protocol Since it was agreed internationally in 1987 to phase out ozone depleting substances, 197 countries have ratified the Montreal Protocol.
The Montreal Protocol also makes important contributions to the realization of the UN Sustainable Development Goals. Given all of these factors and more, the Montreal Protocol is considered to be one of the most successful environmental agreements of all time.
The Montreal Protocol, finalized in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). ODS are substances that were commonly used in products such as refrigerators, air conditioners, fire extinguishers, and aerosols.
The Kigali Amendment to the Montreal Protocol is an international agreement to gradually reduce the consumption and production of hydrofluorocarbons (HFCs). It is a legally binding agreement designed to create rights and obligations in international law.
“The Montreal Protocol is one of the most important and successful global environmental treaties ever,” said David Fahey, director of NOAA's Chemical Sciences Laboratory and Co-chair of the Scientific Assessment Panel of the Montreal Protocol.
The Montreal Protocol has proven to be innovative and successful, and it is the first treaty to achieve universal ratification by all countries in the world.
All countries have ratified the Montreal Protocol and all its Amendments related to ozone depleting substances. In relation to importing and exporting HFCs, the trade provisions of the Kigali Amendment will come into force in 2033.
