Air pollution control, and now in Beijing, Tianjin region can be described as an "enduring" topic.

By 2014, the country is relatively poor air quality before 10 cities, Beijing, Tianjin accounted for 8; the first quarter of this year, a poor former 10 cities, Beijing, Tianjin and has accounted for six. From time to time and to the haze days, so people will inevitably wonder: Why is air pollution in Beijing, Tianjin so hard?

April 22, the CPPCC National Committee held a "Beijing, Tianjin and promote the coordinated development of air pollution control," biweekly consultation forum, members of the CPPCC, Beijing, Tianjin and three Committee Chairman, experts, scholars and government departments responsible comrades gathered to discuss root cause of air pollution in Beijing, Tianjin and collaborative approach prevention.

Air pollution control require regional cooperation, this is the consensus, it is difficulty

For the air pollution in Beijing, Tianjin, one of the most sensitive is the PM2.5 index. So, the source of PM2.5 in Beijing, Tianjin regions in the end is what? This is the first figure out the pollution problem.

"According to the Ministry of Environmental Protection and the Chinese Academy of Sciences, Academy of Engineering study on Beijing, Tianjin, Shijiazhuang particulate matter air pollution sources, the three PM2.5 local sources, motor vehicle accounted for 31% of Beijing, Tianjin, 30% of dust, burning Coal accounts for Shijiazhuang 28.5%, respectively, of the first three sources of pollution. "CPPCC Standing Committee, Vice Minister of Environmental Protection Wu Xiaoqing as reveal the answer.

In order to eliminate the impact of these different sources of pollutants on air quality, three regarded control of coal, motor vehicle pollution control and adjust the industrial structure as an important treatment measures. Such as: Beijing launched the "Beijing 2013--2017 Clean Air Action Plan"; Tianjin implementation of comprehensive grid management of air pollution, if it is found immediately supervise the rectification polluting activities; Hebei province ton output capacity determination, represents rather lower GDP and revenue growth, but also determined to win the battle of air pollution control.

However, air pollution is not easy from the source. Since three adjacent any contaminants of a region are likely to cause pollution to other areas, thus, how the governance of regional collaboration in the atmosphere, is very important.

According to the central deployment, Beijing, Tianjin and the surrounding six provinces and central ministries in the country set up the first working group to combat air pollution in Beijing, Tianjin and surrounding areas. Since Beijing, Tianjin and unbalanced regional development, air pollution in need of regional cooperation, although it is three consensus, but still is difficult. For example, three different emissions standards, motor vehicle environmental regulation is not unified, regional heavy pollution weather emergency plan is not perfect, and so on.

Last November, during the APEC meeting in Beijing "APEC blue" let people see the Beijing, Tianjin and collaborative governance haze hope and effect. Currently, Beijing, Tianjin and share information in the area, heavy pollution weather early warning, consultation and other aspects of emergency response have achieved some success, however, Beijing, Tianjin and three government officials, who invariably report that they expect further break administrative division concept, accelerating regional common legislation.

"Air pollution is characterized by regional and broad-based, joint prevention and control work in the whole management of the most critical issues." CPPCC National Committee, vice mayor of Beijing Cheng Hong said, but now mainly rely on joint prevention and control of administration coordination and promotion. She suggested that the future should be established in the Atmospheric Pollution Prevention Act in a special chapter, explicitly requested the establishment of coordination mechanisms heavily polluted areas of air pollution control, to further refine and clear, unified monitoring, unified warning, these joint prevention and control of specific mechanisms unified emergency, and learn from foreign experience, to develop "Beijing, Tianjin Air Pollution Prevention Act," by the National Research.
