中国冰箱行业淘汰CFCs的环境效益分析

Assessment of Environmental Benefits from Phasing out CFCs in Refrigerator Industry of China

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 Mt CO2-eq和4.7×104 t ODP;2008年后还将减排619.8 Mt CO2-eq和1.0×105 t 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24.2 Mt CO2-eq,对中国节约资源和节能减排具有十分重要的现实意义。

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.
