Refrigeration and air-conditioning (RAC) technologies are the cornerstone of modern life, ensuring comfort, food safety and security, and access to safe medicines. Good practices in the RAC servicing sector will make a difference in not only minimising emissions, hence limiting new production of refrigerants, but also maintaining appliance… read more

This fact sheet summarises and highlights the main elements of the Amendment of particular interest to countries operating under Article 5 of the Protocol (Article 5 Parties).

In 2016, the Montreal Protocol was amended to phase-down the production and consumption of hydrofluorocarbons (HFCs) which are commonly used alternatives to ozone depleting substances.

This document was produced by the UNEP Division of Technology, Industry and Economics (UNEP DTIE) OzonAction Programme under the framework of the UNEP-U.S. Environmental Protection Agency (USEPA) grant partnership project: “Regional Programme for Enhancing Institutional Capacity for HCFC Phase-out linked to Energy Efficiency and Climate… read more

This poster provides a short checklist for customs officers of things to keep in mind when handling ozone depleting substance shipments.

An overview of the basic tools used by RAC technicians in the servicing sector.

Under the Montreal Protocol on Substances that Deplete the Ozone Layer, Article 7 of the Protocol requires all Parties, both developing countries (also called Article 5 countries) and developed countries, to provide statistical data on an annual basis, on various issued related to trade and production of ozone-depleting substances (ODS),… read more

The RAC sector represents a major share of energy use in most developing countries as RAC appl i cat ions consume large amounts of electricity for cooling requirements, resulting in a rapid increase in energy consumption in the commercial and residential sectors of many countries.

United Nations Environment Programme (UNEP) OzonAction Branch, as well as other United Nations (UN) agencies operating under the Montreal Protocol on Substances that Deplete the Ozone Layer, offered over the last two decades exhaustive training programmes for the servicing technicians on the refrigeration good practices including emissions… read more

The number of single component refrigerants with different thermodynamic properties suitable for different types of equipment is limited. Growing demand for refrigeration and air-conditioning with diversified applications has led to a continued search for suitable refrigerant blends. A number of such blends have been developed by mixing two or… read more
