Xinhuanet reports that beginning next year, the Beijing municipal government will slash the annual new car registration quota by one-third, from 150,000 license plates to 100,000.
Of the 100,000, 60% are reserved for new energy vehicles. Beijing currently has registered a total of 137,800 electric cars. The Chinese capital intends to bring the total number of vehicles to around 6.3 million by the end of 2020. . . .
Beijing is also increasing its spending on the public transit system to reduce congestion. By 2020, Beijing’s metro lines will total 900 kilometers (559 miles).
