Refrigerants used in refrigerators are an important source of ozone depleting substances released into the atmosphere, and can have a significantly negative effect on the hole in the ozone layer. But most emission of refrigerants is man-made, unrea-sonable and needless. Since in most emission cases the refrigerants are contained in the refrigerators, we can retrieve them by some technique that changes the 'manual emission' into manual retriev-ing. To promote the retrieval action and diminish the pollution, society can use economic, administrative and technical counter-measures, which can create a 'good-cycle' both 'harnessing pollu-tion and earning income simultaneously', reinforce the motive of retrieving, and retrieve most proportion of refrigerants used by all refrigerators. This 'good-cycle' method can be easily promoted, and also a valuable way to promote other forms of environmental protection. The three countermeasures have almost no social cost, even no cost at all.
