The Beijing-Tianjin-Hebei and surrounding areas deepened the mid- and long-term planning research project on air pollution control and released results in Beijing on May 4. The study mentioned that from a long-term perspective, the industries with the greatest potential for emission reduction in the three regions of Beijing, Tianjin and Hebei are steel, cement and petrochemical respectively. In order to meet the regional air quality target requirements, the steel production capacity of Beijing, Tianjin and Hebei must be controlled at 200 million tons in the future.
According to reports, the research project was launched in 2015. It is organized by the Beijing-Tianjin-Hebei and surrounding areas air pollution prevention and control team office and relied on the Beijing Municipal Environmental Protection Bureau and the Chinese Academy of Environmental Sciences. The study also established for the first time a list of air pollutants emitted from seven provinces (autonomous regions and municipalities) in Beijing, Tianjin, Hebei and surrounding areas, involving seven pollutants and seven major sources of pollution.
At the National Air Pollution Prevention and Control Coordinating Center, deputy director of the Associate Center, Chai Fahe, chief scientist of the Chinese Research Academy of Environmental Sciences, introduced the research results of the project and stated that seven provinces (regions, cities) are Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Shandong, and Henan. The seven pollutants involved are PM10, PM2.5, sulfur dioxide, nitrogen oxides, volatile organic compounds, ammonia, and carbon monoxide. The seven major types of pollutants involved include combustion sources, industrial sources, mobile sources, dust sources, life sources, and agriculture. Source, natural plant source.
Based on the establishment of emission inventory, this research project focuses on the characteristics of atmospheric pollution emission and transmission impact in Beijing, Tianjin, and surrounding areas. Chai Fahe said that in recent years, on the basis of concerted efforts to reduce emissions, although overall regional air quality has improved, the total amount of emissions remains large and the governance situation remains severe, requiring the region to jointly implement more in-depth pollution reduction.
It is understood that Beijing, as one of the key regional cities, began implementing the Ambient Air Quality Standard (GB3095-2012) on January 1, 2013. This new edition of the “National Standard” provides for the continuous monitoring of six pollutants, including the old standards of sulfur dioxide, nitrogen dioxide, PM10, and new PM2.5, ozone, and carbon monoxide. Among them, PM2.5 uses the first phase of the World Health Organization target value, which is 35 micrograms/cubic meter.
"To realize the above national standard, from a long-term perspective, the steel production capacity of Beijing, Tianjin and Hebei should be controlled at 200 million tons." Chai Fahe said frankly that major air pollutants need to be reduced by 40% to 80% on a 2015 basis. Steel, cement and petrochemical industries have the greatest potential for emission reductions.
According to previous reports, Hebei, a major steel province, announced at the two conferences held in early 2016 in Hebei Province that Hebei Province will set a tone of 200 million tons of steel production capacity in the next five years.
The research project also proposes to implement zoning control of the atmospheric environment, implement differentiated energy policies to reduce total coal consumption, promote the unification of regional standards and technological transformation to improve the level of fixed source pollution control, and continue to implement the “control and control of vehicle oil roads”. Based on the optimization of regional transportation layout, the construction of a green traffic system.
