SHANGHAI, Jan. 29 (UPI) -- The Chinese government has announced measures to control air pollution during Shanghai's upcoming six-month World Expo, environmental officials said.
Emergency measures could include production control or even shutting down some heavily polluting companies, the China Daily reported Friday.
The government is also considering vehicle controls, including stopping motorists from driving one day a week based on their license plate number, the newspaper said.
"Although vehicle control measures are primarily intended to ease traffic congestion, it's also a good way to improve air quality, as it would reduce pollutant emissions to a large extent," Zhang Quan, director of the municipal environmental protection bureau, said.
People are being encouraged to take buses and subways to visit the Expo, he added.
Shanghai wants to have more than 95 percent "fair" air quality days this year in its attempt to hold a green World Expo, China Daily said.
