International Institute of Refrigeration ECA Network Meeting in Tirana, Albania, March 2008 Environmental impacts of refrigerating systems

International Institute of Refrigeration Impact on the ozone layer The impact of refrigerating plants on ozone depletion is due to emissions of chlorinated refrigerants (CFCs and HCFCs)  equipment leaks  no recovery  poor maintenance The Antarctica ozone hole

International Institute of Refrigeration Montreal Protocol Industrialized countries Developing countries CFCs Phased-out since 1996 Phase-out by 2010 HCFCs Phase-out by 2020 (1) (2) Phase-out by 2030 (1) (1)Decision taken at MOP-19 in Montreal (September 2007) (2)Several countries have adopted more stringent regulations regarding HCFC phase-out: EU countries, US, Japan, etc.

International Institute of Refrigeration Impact on global warming The global-warming impact of refrigerating plants is the following:  About 20% of this impact is due to direct emissions of fluorocarbons (CFCs, HCFCs and HFCs),  About 80% of this impact results from indirect CO2 emissions originating in the production of the energy used by the refrigeration plants Efforts implemented focus on: Reduction of direct emissions thanks to better containment of refrigerants, development of alternative refrigerants. Reduction of energy consumption thanks to increasing energy efficiency of refrigerating plants

International Institute of Refrigeration Kyoto Protocol The objective of the Kyoto Protocol is to reduce, in 39 developed countries, emissions of a basket of 6 greenhouse gases by at least 5% between 1990 and HFCs are among the 6 greenhouse gases covered by the Kyoto Protocol. CFCs and HCFCs are not included in the basket of Kyoto-controlled gases since they were already covered by the Montreal Protocol.

International Institute of Refrigeration ECA Network Meeting in Tirana, Albania, March 2008 Achievements

International Institute of Refrigeration Reductions in refrigerant emissions (1) Refrigeration played a vital role in ensuring the successful application of the Montreal Protocol.  As before it entered into force, about 40% of the CFCs used were used by the refrigeration sector. The refrigeration sector has widely contributed to the predicted recovery of the ozone layer by 2060.

International Institute of Refrigeration Reductions in refrigerant emissions (2) By reducing drastically the use of CFCs and HCFCs, the refrigeration sector has significantly contributed to climate change mitigation  Over 5 Gigatonnes of CO 2 equivalent annual emissions have been eliminated (1) :  It represents more than 25% of global greenhouse gas emissions compared to 1990  This is 5 times the Kyoto Protocol's target for reducing GHGs emissions by Velders GJM, Andersen SO, Daniel JS, Fahey DW, McFarland, M.,2007, The importance of the Montreal Protocol in protecting the climate

International Institute of Refrigeration Reductions in energy consumption Examples:  COP in commercial refrigeration (for a temperature lift of 30°C):  1960: about 2.5  1990: about 3.3  2007: about 4  Energy consumption of new refrigerators  About 4 times less in 2007 than in 1973  Heat pumps  The 130 million heat pumps currently in use enable 1300 TWh/y of heating to be produced and reduce CO 2 emissions by 130 MT/y

International Institute of Refrigeration Conclusion Refrigeration is just one part of overall solutions leading to reduced energy consumption in housing and transport Plant maintenance and leak tightness and recovery of stocks of CFCs and HCFCs refrigerants remain vital issues Replacement of ozone depleting refrigerants must also consider energy efficiency and other potential impacts such as safety and cost Research must be stepped up in order to optimize alternative technologies that are developed, to enhance the energy efficiency of this equipment and to generally reduce the impact of refrigeration technologies the equipment on the climate Replacement solutions must take into account the specific contexts in the least developed countries, particularly in terms of cost It is vital to inform and train refrigeration engineers and technicians in order to successfully implement these solutions.
