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… read more

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.

Mobile air-conditioning (MAC) systems 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… read more

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 which… read more

In Kigali Fact Sheet 6 the development of a national HFC phase-down strategy is discussed. That Fact Sheet 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… read more
