In the Kigali Amendment the Protocol was extended to control the production and consumption of HFCs. These are not ODS, but they are very powerful greenhouse gases (GHGs). This Fact Sheet provides details of which substances are controlled under the Montreal Protocol and gives examples of related substances that are not included in these controls.English
Many of the commonly used refrigerants are mixtures of several pure fluids. The Kigali Amendment controls the use of HFCs, including those used in refrigerant mixtures. This Fact Sheet provides details about the GWP of refrigerant mixtures.English
Mobile air-conditioning (MAC) systems are used to cool the driver and passengers in land transport including cars, vans, lorries, buses, agricultural vehicles and trains. Historically all car air-conditioning used the refrigerant CFC-12. This was completely phased-out during the 1990s in developing countries and around a decade later in developing countries and the global car market switched to HFC-134a, a refrigerant with a GWP of 1430. Larger vehicles such as buses and trains also use other HFC refrigerants such as R-407C (GWP 1774) and R-410A (GWP 2088).
The most widely used fire protection systems (FPS) involve water based systems such as automatic sprinklers. An important category of FPS are chemical agents that can quickly extinguish a fire without creating some of the consequential damage that is created by water-based FPS. Historically, the most important chemical agents were halons. These are compounds containing bromine that were extremely effective at extinguishing certain categories of fire.English
In Kigali Fact Sheet 6 the development of a national HFC phase-down strategy is discussed and gives background information on the “core actions” that can be used to deliver the required cuts in HFC consumption. It was stressed that the most important long-term core action is to use lower GWP alternatives to HFCs in all new equipment. In this Fact Sheet we show how the choice of refrigerant selected in new equipment has a strong influence on the rate of HFC phase-down.English

Under the Kigali Cooling Efficiency Program (K-CEP), UN Environment is implementiong a two-year "twinning" project to build the capacity of National Ozone Officers and national energy policymakers for linking energy efficiency and Montreal Protocol objectives in support of the Kigali Amendment.English
The project “Demonstration of a Regional Strategy for ODS Waste Management and Disposal in the ECA Region” was prepared jointly by UN Environment and UNIDO, on behalf of the Governments of Bosnia and Herzegovina, Croatia, and Montenegro.
The objective of the project was to evaluate a regional approach for ODS waste disposal in terms of cost - effectiveness and sustainability, particularly in LVC countries that do not have ODS destruction facilities. The project proposal aimed at environmentally sound destruction of 29.07 MT of ODS waste from the participating countries.English
