UN program attendees in Beijing cite vehicles' contribution to dirty air

The government should set higher standards for vehicle emissions while promoting cleaner fuels to deal with the significant contribution of motor vehicles to air pollution, environmental officials and experts said on Monday.

More than 100 cities were shrouded in thick smog and haze for the past week. National alarms for smog and haze that lasted for seven days were not lifted until Monday morning, according to the National Meteorological Center.
