Chinese capital Beijing and its surrounding areas are planning a surveillance network to deal with car exhaust fumes and reduce smog.

The regional platform will realize data sharing in different places and strengthen coordinated law enforcement to improve the vehicle emission monitoring, said Li Kunsheng, a vehicle exhaust administration official of the Beijing Environmental Protection Bureau.

"It is an important move for regional air pollution treatment, "said Li at a meeting on joint air pollution treatment for Beijing, Tianjin, Hebei and surrounding areas, in Beijing on Thursday.

A network covering Beijing, Tianjin and Hebei will eventually be expanded to include Shanxi Province, Shandong Province and Inner Mongolia Autonomous Region. Currently, standards differ in terms of emissions of new vehicles and the road surveillance.

At the end of July, the number of vehicles in Beijing reached 5.58 million. In addition, another 200,000 cars enter or pass Beijing each day.

Vehicle emissions, such as carbon monoxide, hydrocarbons and nitrogen oxides, account for 86 percent, 32 percent and 56 percent respectively of the totals of these pollutants in Beijing's air. Vehicles provide 31 percent of PM2.5 pollutants in Beijing, with 20 percent in Tianjin and 15 percent in Shijiazhuang, capital of Hebei.
