How high is the “contribution†of motor vehicles to urban air pollution? At the Tianjin Teda Automobile Forum held last weekend, the relevant person in charge of the Beijing Municipal Environmental Protection Bureau said that more than half of the hydrocarbons and nitrogen oxides emitted by motor vehicles will be converted into PM2.5, which is actually “polluting PM2.5â€. The contribution rate is above 40%. To improve motor vehicle pollution, the key measure is to improve oil and emissions standards. According to reports, the current draft of the sixth phase of the city's motor vehicle emission standards and oil standards has been basically formulated, and strive to implement in 2017.
The upgrade of Beijing's automobile emission standards and supporting oil products has already been faster than the national pace. From February 1, 2013, Beijing officially implemented the fifth-phase motor vehicle local standard (referred to as “Beijing Fiveâ€), and light-duty gasoline vehicles that did not meet the “Beijing Five†standard have withdrawn from the Beijing new car sales market. As early as May 31, 2012, the Beijing Gas Station had fully supplied the fifth-stage local standard motor gasoline, and the grades were adjusted to No. 89, No. 92 and No. 95 by No. 90, No. 93 and No. 97 respectively. According to the requirements of the Ministry of Environmental Protection, the fifth phase of vehicle fuel will be supplied in key regions including Beijing, Tianjin and Hebei in 2017, and the fifth phase of vehicle emission standards will be implemented. The second phase will be supplied nationwide from 2018. Car fuel. The Beijing-European emission standard in the brewing will make Beijing's automobile emission standards more advanced and become one of the most stringent emission standards in the world. This also means that more new models with lower technology levels will be withdrawn from Beijing, and more consumers and car units may switch to buying zero-emission new energy vehicles.
Li Kunsheng, director of the Motor Vehicle Emissions Management Office of the Municipal Environmental Protection Bureau, said that the "Jingliu" standard has greatly improved compared with the current "Beijing Five" standard and the "European Standard". This has basically reached a consensus with oil and petrochemical enterprises. In terms of oil products, the sulfur content of the “Beijing Six†standard is consistent with “Beijing Five†and is still below 10 PPM. In addition, gasoline will further reduce olefins, aromatics, vapor pressure, distillation range, benzene and other indicators, diesel will further reduce polycyclic aromatic hydrocarbons, density and other indicators. The city's motor vehicles will achieve the turning point of fuel consumption in the case of increasing total volume, and achieve a simultaneous decline in fuel consumption and vehicle emissions. Strive to achieve at least 5% reduction in vehicle fuel consumption in 2017 compared to 2012, and reduce nitrogen oxides, volatile organic compounds and PM particulate matter by 25%, 20% and 35%, respectively.
It is also understood that at the end of August, the new air pollution prevention and control law has passed the final review by the National People's Congress. The new law will be implemented on January 1 next year, and the punishment for excessive emission control will be unprecedented.
“In terms of exhaust emissions, the problem of light-duty vehicles is small, and there are many problems with heavy-duty vehicles. It is true that 80% to 90% of heavy-duty car stickers are found at the intersections, but the actual emissions are not up to standard, and this kind of large-scale fraud The impact of air pollution in Beijing is very large.†Li Kunsheng revealed that after the new “Air Pollution Prevention and Control Law†was officially implemented, once the fraud and excessive standards were found, the first step required rectification, and the second step would confiscate the illegal income. The new law clearly stipulates that a fine of two to three times is imposed on the sales of the market. "That is, if you sell 10,000 new cars with excessive emissions, each car is calculated at 100,000 yuan, doubled to 10 billion, twice as much as 2 billion." Li Kunsheng said, the third step is still right. The vehicle that meets the standard is recalled and will be required to be destroyed if it is handled improperly.
In addition, if an individual uses a car that does not meet the standard, he will face a penalty of 5,000 yuan according to the new law. "Heavy-duty vehicles with abnormal exhaust gas after-treatment devices will also be fined 5,000 yuan." Li Kunsheng said.
According to reports, the joint supervision office for motor vehicles established by the seven provinces and municipalities of Beijing, Tianjin, Hebei, Shanxi, Shandong, Henan and Mongolia has been formally established. The next step will be cross-enforcement, joint law enforcement, and enforcement in different places. Strengthen the supervision of motor vehicle emissions.
