Capital bans polluting heavy-duty vehicles
Beijing started banning heavy- duty diesel vehicles that cannot meet the fifth phase emissions standard, becoming the first Chinese city to fully adopt the national standard.
The move will cut emissions of pollutants, according to Li Kunsheng, a vehicle exhaust administration official with the Beijing Environmental Protection Bureau.
From June 1, only heavy diesel vehicles that meet the standard will be issued license plates. Other types of gasoline and diesel automobiles have been subject to the standard for two years.
Vehicle emissions are the prime cause of air pollution in Beijing.
The capital city has about 220,000 heavy diesel vehicles, each weighing at least 3.5 tons, accounting for 4 percent of all vehicles in the capital. However, they account for 50 percent of all vehicle emissions of nitrogen oxides and 90 percent of particles.
