BEIJING - The Beijing municipal government will slash its new car registration quota by 37.5 percent starting from 2014 and give more stake to new energy vehicles as part of its efforts to curb air pollution.

According to an interpretation of a five-year vehicle emission reduction plan (2013-2017), the number of newly registered cars will be cut from current 240,000 each year to 150,000 by 2017.

A five-year clean air action plan (2013-2017), released on September 12, ruled that the total number of vehicles in the city would be restricted to around 6 million by the end of 2017.

The city had 5.4 million vehicles at the end of October, according to figures from the Beijing Traffic Management Bureau.

Among the 600,000 vehicles allowed to hit the road within the next four years, 170,000 will be new energy vehicles which include battery electric, plug-in hybrid and fuel cell ones.

In 2014, a quota of 20,000 new car registration will be given to new energy vehicles, and 30,000 in 2015.

In 2016 and 2017, that figure will be doubled from that for 2015 to 60,000 respectively.
