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, 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 parties to the Protocol meet once a year to make decisions aimed at ensuring the successful implementation of the agreement. These include adjusting or amending the Protocol, which has been done six times since its creation.
The latest amendment to the Montreal Protocol is known as the Kigali Amendment. It was adopted in 2016 during a meeting held in Kigali, Rwanda.
Governments are not legally bound until they ratify the Protocol as well as the Amendments. Unfortunately, while most governments have ratified the Protocol, ratification of the amendments and their stronger control measures lag behind. As of today, the Ozone Agreements had been signed by 193 nations.
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.
