Beijing's Environmental Protection Bureau said that over 30 percent of air pollutants in China's capital come from automobile exhaust, The Beijing News reported Wednesday.
Chen Tian, head of the bureau, announced the sources and components of the city's serious smog weather on Tuesday.
Chen said experts from environmental authorities and scientific research institutes in China came to the results based on a one-and-a-half year research project in Beijing's smog contents.
Thus, the city plans to enforce the "Beijing VI Standard" for automobile exhaust emissions in 2016, which calls for better gasoline and lower carbon emissions.
According to the city's five-year action plan on clean air, new energy vehicles are the top priority. Buses, taxis, post and sanitation vehicles should take the lead. By 2017, 200,000 automobiles in Beijing are expected to use clean energy.
Besides, 1,200 heavy-polluting companies must close by 2017.
Beijing's neighbors, Hebei province and Tianjin municipality, also contribute heavily to the capital's pollution. Wang Gengchen, researcher at the Institute of Atmospheric Physics at the Chinese Academy of Sciences, suggested the three areas should set up a coordinated network to control smog.
Shijiazhuang, capital of Hebei province, plans to get 53,000 heavy-polluting vehicles off its roads by the end of this year. Baoding, another heavily-polluted city in the province, has closed more than 4,000 heavy-polluting companies. Meanwhile, Xianghe county will plant a five-kilometers-wide "green belt" on its 103-kilometer border to Beijing and Tianjin.1 2
