BEIJING – The Beijing Environmental Protection Bureau released the exposure draft of the Beijing-VI emissions standards recently, including three standards for light-duty vehicles, heavy-duty vehicles and heavy-duty engines. The standards, also known as the strictest emissions standards ever, will be implemented starting from December 1, 2017.
The Beijing-VI standards for light-duty vehicles borrowed the emissions standards of California Air Resources Board, the strictest standards around the world, and are estimated to be 40 percent stricter than the current State-V standards. Auto manufacturers are able to produce standardized models in certain period since matured technology is available in the U.S., said the Bureau. Vehicle cost will not largely increase after mass production.
The emissions standards for heavy-duty vehicles this time is the first of its kind around the world, according to the Bureau.
Beijing enforced the Beijing-I, II, III, IV and V emissions standards in 1999, 2002, 2005, 2008 and 2013 respectively, three years earlier than the national standards implementation, and received good emissions reduction effects. The new Beijing-VI standards is estimated to reduce 40 to 50 percent of emissions for gasoline-engine light-duty vehicle and diesel-engine heavy-duty vehicle per unit.
Vehicle parc of Beijing has exceeded 5.5 million units with 600,000 newly added or updated vehicles each year. The city’s motor vehicle emissions would be reduced by 20-30 percent in 2022 if 50 percent of motor vehicles in Beijing reached the Beijing-VI standards in the next four to five years, said the Bureau.
