Edward Wong, reporting for the New York Times:
The Beijing government put in place emergency measures on Wednesday to try to combat thick smog that has encased the city, which the Communist Party has hailed as a showcase capital, in brown and gray soot. The measures include temporarily shutting down more than 100 factories and ordering one-third of government vehicles off the streets, according to official news reports.
Seems to me it would just be easier to enact pollution controls and be done with it. If there’s one thing businesses don’t like, it’s uncertainties like this.
