Abstract: Facing the international controversy about the regional scale emission of Chlorofluorocarbons( CFCs) ,the main gases,CFC -11 and CFC -12,caused by industrial production in China wereanalyzed. The research progresses on CFCs in key areas of China and the occurrence of CFCs were dis-cussed. The progress of CFCs elimination by the Chinese government was summarized. The analysisshowed that around 2011 and 2016,the decline of CFC-11 and CFC-12 concentrations in atmosphereslowed down. Their concentrations even increased abnormally. The elimination progresses in East Asialagged behind the world’s average,and its decline rate fluctuated greatly. Since 2000,the decline rateof CFCs in China had been ahead of other countries in East Asia. However,after 2015,the decline ratein China slowed down significantly,and the concentration even increased. Although the eliminationprocess of CFCs in China has entered the middle and late stage,strict supervision is still required.There are many influencing factors of atmospheric environmental pollution,which should be comprehen-sively evaluated in combination with the development status and governance efforts of each country.
