In response to the hot spot of pollution of diesel large trucks in the Beijing-Tianjin-Hebei region, Liu Youbin, inspector of the Propaganda and Education Department of the Ministry of Environmental Protection, said on the 23rd that the Ministry of Environmental Protection will promote and unite relevant departments and localities to adjust the transportation structure as air pollution. Important measures for governance, improve railway freight transport capacity, improve railway transportation services, promote container sea-rail combined transport, and accelerate the increase of railway transport ratio.
At the regular press conference held by the Ministry of Environmental Protection on the 23rd, Liu Youbin said that in recent years, the air quality in the Beijing-Tianjin-Hebei region has improved overall, but the average concentration of nitrogen dioxide has not decreased with the average concentration of PM2.5, PM10 and sulfur dioxide. However, in addition to individual cities, the concentration of nitrogen dioxide exceeded the standard.
According to statistics, in the total volume of freight in Beijing-Tianjin-Hebei region in 2016, road transport accounted for 84.4%; road freight in the region is mainly heavy-duty diesel vehicles, with a total of about 830,000 vehicles, accounting for about 4% of the car ownership in the region, nitrogen Oxide emissions account for one-fifth of the total NOx emissions in the region. This year, the number of heavy-duty trucks in the region is still growing at double-digit rates. Heavy-duty trucks in the Beijing-Tianjin-Hebei region have excessive reserves, excessive growth rates, and high levels of nitrogen oxides, which are one of the main reasons for the excessive concentration of nitrogen dioxide in urban areas.
Studies have shown that the main pollutants consumed by the unit cargo turnover of railway freight transportation and unit traffic are only one-seventh and one-third of the road freight. "Adjusting the transportation structure of the Beijing-Tianjin-Hebei region, guiding freight transportation from highways to railways, and reducing the intensity of heavy-duty diesel trucks is one of the key measures to improve air quality in the Beijing-Tianjin-Hebei region." Liu Youbin said.
According to reports, in order to promote the adjustment of freight transportation structure based on road transportation, the Ministry of Environmental Protection has strengthened the environmental supervision of vehicles in use in recent years with the support of the transportation and public security departments. In April this year, the Ministry of Public Security issued a notice to add a national unified code for excessive discharge penalties in the traffic violation punishment system. The joint law enforcement mechanism of “environmental forensics and public security punishment†has been established and effectively implemented.
At present, Tianjin Port, Huanghua Port, Tangshan Port, Qinhuangdao Port, Weifang Port, Yantai Port, etc. have stopped accepting coal from the port. Liu Youbin revealed that the Ministry of Environmental Protection will encourage the development of clean freight fleets and implement peak-peak transportation. During the early warning of heavy pollution, diesel trucks will be prohibited from transporting production materials. At the same time, it will speed up the construction of a remote sensing monitoring network for interconnection and sharing, and adopt comprehensive all-weather and comprehensive control measures for high-emission vehicles such as diesel trucks to achieve illegal vehicles such as excessive discharge and overload exceeding the limit.
