Special plates for new energy vehicles, tantamount to identification cards, will be issued in all cities to help the police with traffic management, the Ministry of Public Security said.

Vehicles with such plates can access favorable policies more directly and easily.

China has more than 1 million new energy cars. Backed by favorable policies like tax cuts, their number is growing across the country. But while promoting these environment-friendly vehicles, measures have to be taken to address technical issues related to them like battery recharging facilities.

Though new energy vehicles are in line with the trend of using clean energy, their popularization can't depend on the government's efforts alone. Supportive facilities have to be constructed and the technology has to be upgraded and the quality improved so that even if the favorable polices are withdrawn some day, people will still want to buy new energy vehicles.
