Home > Programme > Climate Change Portal > Project > ODS Pacific Ozone Depleting Substances (ODS) ProjectProject SummaryThe Pacific ODS Project is the outcome of an approved "Regional Strategy to Implement the Montreal Protocol (on Substances that Deplete the Ozone Layer) in Pacific Island Countries". The Montreal Protocol is an international agreement that is designed to eliminate the production and consumption of harmful ozone depleting substances. These subtances include chemicals such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), carbontetrachloride, halons, and methyl bromide which have many applications including refrigeration, air conditioning, foam blowing, cleaning electronic components, solvents, fire extinguishers, and quarantine and pre-shipment. The ozone layer is found in the stratosphere 10-50km above the Earth and has the vital role in protecting the Earth from the sun's harmful ultraviolet radiation (UV-B) radiation. Increased exposure to UV-B radiation increases the chance of developing certain types of skin cancers. UV-B radiation also affects terrestrial and aquatic ecosystems, altering growth, food chains and biochemical cycles. This radiation damages the aquatic life living just below the surface of salt and fresh water, which form the basis of the Earth's food chain. In the Pacific, the use of ODSs controlled by the Montreal Protocol is limited to CFCs, HCFCs and methyl bromide. The first two are used solely for refrigeration and air-conditioning uses. Most methyl bromide is used for "Quarantine and Pre-Shipment" (QPS) applications, as defined by the Protocol. There are no manufacturing facilities and no new installations of refrigeration equipment using CFCs in any of the countries. CFC-12 and to a much smaller extent, CFC-502 are now used exclusively in servicing existing mobile air-conditioners (MACs), (cars, trucks and buses), domestic refrigerators and small commercial refrigeration equipment. In most countries, the servicing of MACs is the largest ongoing use of CFCs.
