Abstract: The environmental benefits for phasing out CFCs in China’s refrigerator sector, such as the reduction of emissions of greenhouse gases, ozone-depleting substances and the electricity consumption, were analyzed by comparing the scenario of phasing out CFCs to the non-Montreal Protocol baseline scenario, respectively. It was found that 273.5 million tons CO₂-eq and 4.7×10⁴ tons ODP had been reduced by the end of 2008. After 2008, 619.8 million tons CO₂-eq and 1.0×10⁵ tons ODP will be reduced. Phasing out CFCs in China’s refrigerator industry made a considerable contribution to relieve global warming and reduce ozone depletion substances. By using substitute refrigerants, 2.8×10¹⁰ kWh of electricity was saved, which was equivalent to 24.2 million tons CO₂ and of great practical significance in China’s resource conservation, energy-saving and emission-reduction.

摘要： 以无《蒙特利尔议定书》的情景为基线情景, 从消耗臭氧层物质排放、温室气体排放及冰箱耗电量角度分析中国冰箱行业履约淘汰 CFCs 产生的环境效益。结果表明,截至2008年底,中国冰箱行业淘汰 CFCs已实现减排 273.5 MtCO₂-eq 和 4.7×10⁴t ODP; 2008 年后还将减排 619.8 MtCO₂-eq 和 1.0×10⁵t ODP;通过采用更加节能的制冷剂,截至 2008 年底累计节电 2.8×10¹⁰ kWh, 折合减排 24.2MtCO₂-eq,对中国节约资源和节能减排具有十分重要的现实意义。
