In order to speed up the elimination of yellow label vehicles and old vehicles in our city, and further reduce vehicle emissions, the implementation rules of the Air Pollution Prevention Action Plan and the implementation of the Yellow Label Vehicle and Old Vehicles in Tibet Autonomous Region in 2014 "Instructed spirit, since the beginning of this month, Lhasa City has carried out special campaigns for the elimination of yellow-label vehicles and old vehicles. It is estimated that by 2015, the yellow-label vehicles that are publicly owned and used for operation will be basically phased out by the end of 2005; by 2017, all the yellow-label vehicles that are publicly owned and used for operation will be eliminated.
The yellow label car is another name for vehicles with high pollution emissions. It refers to gasoline vehicles whose emission levels do not meet the national I emission standards and diesel vehicles that do not meet the national III emission standards. Because it is a yellow environmental label, it is called a yellow label car. Older vehicles refer to vehicles that have been used for a long time and have poor pollution control levels and have not met the national IV emission standards.
According to research by relevant departments, motor vehicle exhaust emissions are the primary source of urban air pollutants, while yellow-label vehicles and old vehicles are the main sources of vehicle pollutant emissions, as yellow-label vehicles and older vehicles are generally older. Large, vehicles are seriously aging, and the pollutants emitted are significantly higher than the green standard vehicles.
Taking a gasoline vehicle as an example, the pollutant discharge of a yellow standard vehicle is equivalent to the total discharge of pollutants of 14 National III standards or 28 National IV standard green standard vehicles. The exhaust gas contains a large amount of toxic and harmful pollutants. These substances are highly susceptible to complex physical and photochemical reactions in high temperature and humid environments to form PM2.5 and ozone pollution, resulting in excessive concentrations and reduced atmospheric visibility, which is one of the important factors for the formation of haze. At present, motor vehicle exhaust emissions are one of the main factors affecting the current ambient air quality in our city.
According to the "Notice of the People's Government of the Tibet Autonomous Region on Printing and Distributing the Implementation Rules for the Air Pollution Prevention and Control Action Plan" this year, it is strictly forbidden to sell or transfer yellow-label vehicles from June this year, and the public security traffic management department will stop handling the procedures for the transfer of yellow-label vehicles. By the end of 2014, the local (city) administrative department (the People's Government) will fully implement the yellow label and heavy trucks, and the area and time limit should be strictly defined. By 2015, the yellow label vehicles registered for public operation and for operation before the end of 2005 will be basically phased out. By 2017, all the yellow-label vehicles that are publicly owned and used for operation in the region will be eliminated.
In order to control the total amount of motor vehicle pollutants discharged from our city, effectively protect the health of the people and improve the quality of the atmospheric environment, the environmental protection department hopes that the general public friends and car owners will actively participate in the work of eliminating yellow-label vehicles and old vehicles in our city. .
