Haze means absence of wind which makes it impossible to "blow away" the pollutant cover gathering in the sky, which, in turn, means there is only one way of reducing it, that is mitigating pollution sources.
Beijing had 45 heavy pollution days last year, according to a report by Beijing environmental protection bureau on Beijing's air quality. Statistics indicate that the annual concentration of the city's main atmospheric pollutant -- PM2.5 -- dropped by 4 percent on a year-on-year basis, but just fell short of the year's target of 5 percent.
