The OzonAction Branch of the Law Division has been strengthening the capacity of governments – particularly the operational focal points for the Montreal Protocol, known as National Ozone Units – as well as industry, customs and enforcement agencies in developing countries to elaborate and enforce the policies required to implement the Protocol… read more

Under the Kigali Cooling Efficiency Program (K-CEP), UN Environment is implementing 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.

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

Following the adoption of the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, UN Environment's OzonAction prepared a series of fact sheets describing the immediate and future challenges to be addressed by the different Parties between now and until the amendment comes into force.

This fact sheet provides a summary of what Parties need to do when introducing new national legislation and setting up appropriate administrative procedures with regard to the implementation of the Kigali Amendment.

A quick run-through of the different stakeholders that each Party must engage vis-à-vis the Kigali Amendment to ensure its successful and efficient implementation.

This fact sheet discusses some of the technical issues related to the operation of air-conditioning systems at high / extremely high ambient temperature

This fact sheet gives guidance on the impact of using flammable HFC alternatives.

This fact sheet discusses the various barriers to the successful implementation of the Kigali Amendment

The interaction and linkages of the Kigali Amendment with other existing policy measures is described in this fact sheet

The benefits and advantages of quick action to avoid costs and achieve target environmental results are explained in this fact sheet.

A look at the considerations and actions that Parties must make to come up with an optimal HFC phase-down strategy.

An overview of lower GWP alternatives and how these are being introduced into the different market sectors and sub-sectors.

This fact sheet shows the four country groupings under the Kigali Amendment and provides a summary of the timetables and explains how to calculate the HFC baseline.

This fact sheet provides a list of the definition of terms and acronyms used in the Kigali Fact Sheet series as well as links to other useful information.

This fact sheet shows the importance of understanding how ‘tonnes CO2 equivalent’ is calculated and gives the GWP values for substances controlled under the Kigali Amendment.
