Cars will be allowed on the road only on alternate days during red alerts for air pollution in Guangzhou, Guangdong province, under measures the city government approved on Monday.
In addition, 30 percent of government cars will remain garaged if air pollution hits serious levels, and key enterprises will have to cut 30 percent of their emissions during a red alert, the highest level.
Under the alert system approved on Monday, a red alert will be issued when the air quality index is forecast to exceed 300 at more than half of the city's 10 monitoring stations.
During orange alerts, issued when air quality index levels of 201 to 300 are forecast, businesses that fail to meet emission standards will have to cease emissions altogether, and 20 percent of government vehicles will stay off the road.
Construction sites that put dust and fumes in the air, as well as fireworks and outdoor barbecues will be banned during orange alerts.
The government's fleet of 13,000 cars accounts for about 0.6 percent of the cars in Guangzhou, Yang Liu, director of the city's environmental protection bureau, said at a news conference on Monday.
"In difficult times, public servants should take the lead in taking action to address environmental pollution."
Yang said Guangzhou Mayor Chen Jianhua pledged to go to work by subway during any environmental emergencies.
Asked whether schools would be suspended during a red alert, Yang said education authorities would address that issue.
In the past three years, the city's air quality has never deteriorated to a level that would today prompt a red alert, Yang said.
An orange alert would have been issued twice in 2011 and three times last year. No orange alert would have been warranted so far this year.
Guangzhou's air quality complied with the standard on 210 of the 274 days in the first three quarters of this year, according to Yang's bureau.
Excellent air quality was recorded on 73 days, good air quality on 137 days, light pollution on 55 days and medium pollution on eight days.
Readings that failed the standards mainly involved ozone, nitrogen dioxide and PM2.5 — particulate matter smaller than 2.5 micrometers in diameter.
Of the six air pollution indexes, the PM2.5 reading failed the standard by the largest margin, averaging 47 micrograms per cubic meter and exceeding the standard by 34 percent in the three quarters.
Guangzhou's PM2.5 readings will decrease by more than 6 percent in 2015 compared with the 2010 levels, according to the city's environmental protection plan.
