Recently, the "Beijing 2013-2017 Clean Air Action Plan Important Task Decomposition" was released, and the city's governance includes atmospheric pollutants including fine particulate matter PM2.5. Among various pollution control measures, motor vehicle pollution prevention is undoubtedly an important link.
The newly announced Clean Air Action Plan shows that the number of motor vehicles in Beijing will be controlled within 6 million vehicles in 2017. The reporter learned from the Beijing Municipal Traffic Management Bureau that as of the end of July 2013, the number of motor vehicles in Beijing was 5.354 million. This means that in the next four years, the average annual growth rate of motor vehicles in Beijing will be about 140,000 units, which is more than 30% less than the growth in 2012.
The current state of air 22% of PM2.5 comes from the relevant person in charge of the Beijing Municipal Environmental Protection Bureau. The pollution sources in Beijing are mainly divided into four categories, including motor vehicle exhaust emissions, coal burning, food fume, industrial emissions and construction dust. Motor vehicle exhaust is an important source of air pollution, with approximately 22% of PM2.5 coming from exhaust. As of the end of July 2013, the number of motor vehicles in Beijing has reached 5.354 million.
According to environmental experts, motor vehicles are low-altitude, mobile emission sources, and the pollutants are complex. The pollutants are mainly by-products of the combustion process of the fuel in the engine and the volatiles of the fuel itself. The pollutants in automobile exhaust are mainly carbon monoxide (CO), hydrocarbon (HC), nitrogen oxides (NOx) and particulate matter (PM2.5), accounting for 85.9%, 25.1%, 56.9% of the total air pollution, respectively. twenty two%. In addition, the motor vehicle fuel tank also emits volatile organic compounds during the refueling process and when the crankcase leaks.
Motor vehicle exhaust emissions not only affect air quality, but also cause harm to human health. Yesterday, experts from the Department of Rehabilitation of Peking University School of Medicine and Capital Medical University told reporters that motor vehicle exhaust is extremely harmful to human health, especially the fine particulate matter PM2.5, which can attract into the deepest part of the lungs, causing or Aggravating asthma, acute respiratory symptoms (such as coughing dyspnea or respiratory pain), lung function damage, and chronic bronchitis are particularly harmful to the elderly and children. "This group of people is in a traffic jam and will produce very much Significant respiratory response to respiratory discomfort."
Clean targets strive to implement the national VI standard in 2016
In recent years, Beijing has continuously increased the management of motor vehicles. By 2017, the number of motor vehicles will be controlled within 6 million vehicles, and 1 million old vehicles will be eliminated. While controlling the number of motor vehicles, it will continue to improve. The environmental quality of motor vehicles.
The reporter learned from the Beijing Municipal Environmental Protection Bureau that since 1998, Beijing has successively formulated and revised more than 30 standards for controlling vehicle emission standards and related standards. In 2000, with the approval of the Municipal People's Congress, the "Beijing Implementation Measures" was formulated, which added relevant contents of motor vehicle emission management. At present, Beijing Municipality is currently formulating the "Beijing Air Pollution Prevention and Control Regulations" in conjunction with the current actual situation, and is expected to be released in 2014.
Increasing the emission standards of new vehicles is an internationally accepted practice to reduce vehicle emissions. The implementation of new vehicle emission standards in Beijing is two to three years ahead of the national level. Approved by the State Council, Beijing successively implemented national I, II, III, IV and Beijing motor vehicle emission standards in 1999, 2002, 2005, 2008 and 2013. The sixth phase of motor vehicle emission standards is planned to be implemented in 2016.
Through experiments, every time a vehicle exhaust emission standard is increased, the pollution of bicycle emissions can be reduced by 30% to 50%. At the same time, matching the corresponding standard oil products not only ensures the normal use of the new emission standard vehicles, but also reduces the emission pollution of the used vehicles. According to the experiment, every time the vehicle oil standard is increased, the pollution of bicycle emissions can be reduced by 15% to 20%.
In terms of speeding up the elimination of old vehicles, in 2009 and 2010, Beijing eliminated or renovated 156,000 yellow-label vehicles, basically solving the problem of high-emission yellow-label vehicles. On August 1, 2011, Beijing implemented the “further promotion plan for the elimination of old motor vehicles in this city†and adopted the government subsidy policy to promote the elimination and renewal of old vehicles. From the date of implementation of the plan to the end of 2012, a total of 507,000 old cars were eliminated. According to estimates, the elimination of 507,000 old cars will reduce carbon monoxide, nitrogen oxides and hydrocarbon emissions by 179,000 tons per year. At present, the elimination and renewal of old cars is progressing smoothly. By the end of July, 176,000 old cars have been eliminated (180,000 vehicles are planned to be eliminated throughout the year).
In addition, Beijing has also strengthened supervision over the use of vehicles, and adopted a series of regulatory measures such as road junction inspection, road inspection night inspection, household sampling, remote sensing monitoring and regular annual inspection, and carried out law enforcement supervision work for many years. In order to increase law enforcement efforts, promote the emission of motor vehicles up to standard. The reporter learned that the Beijing Municipal Air Pollution Prevention and Control Regulations, which are currently under review, have increased the penalties for excessive emission vehicles. The penalty for each vehicle is 100 yuan, which is increased to 500 yuan or more per vehicle. It is used in the standard of the car.
