Investigating the environmental benefits of the complete phase-out of HCFC-22 in Jamaica


For decades there have been serious concerns globally for the cause and impact of ozone layer depletion and climate change phenomenon. To contribute to the eradication of Ozone Depleting Substances (ODS), Jamaica, guided by a Hydrochlorofluorocarbons Phase-out Management Plan (HPMP) is presently on a schedule to phase-out the consumption of all Hydrochlorofluorocarbons (HCFCs) by 2040. A review of import data revels that HCFC-22 typically accounts for over 97% of the HCFCs imported in Jamaica since implementation of the HPMP. The aim of this study was to explore the environmental beneļ¬ts of the complete phase-out of HCFC-22consumption in the Refrigeration and Air Conditioning service sector in Jamaica. The analysis explored the environmental benefits of replacing HCFC-22 with the natural refrigerant Propane (HC-290) which is a Hydrocarbon substance with zero Ozone Depleting Potential (ODP) and low Global Warming Potential (GWP). This is being done because any effort to significantly reduce the consumption of HCFCs in Jamaica should also specifically focus on reducing HCFC-22 consumption. It has been shown that HC-290 is an attractive alternative to HCFC-22 from an environmental perspective and replacing HCFC-22 with HC-290 in small air conditioning systems (under 2 tons cooling capacity) will have a significant impact on the reduction of greenhouse gas emissions and electricity consumption.
