According to the Beijing Environmental Protection Bureau, Beijing will implement new vehicle emissions standard in December 2017. The new standards will be the strictest of anywhere in the world.
In 2007, Beijing took the lead in China in using unleaded gasoline. In 2004, Beijing worked out and implemented the Beijing II gasoline standard. Later, in 2005, 2008 and 2012, Beijing issued and implemented Beijing III, Beijing IV and Beijing V gasoline standards. Gasoline standards in Beijing are always one or two stages ahead of other Chinese cities. The newest standard, Beijing VI, will reduce vehicle hydrocarbon emissions by 5 percent.
Beijing is expected to implement the new standard on December 1, 2017. The new, strictest standard will lower emissions by 40 to 50 percent. It is predicted that by 2022, overall vehicle emissions pollution in Beijing will be reduced by 20 to 30 percent.
