Beijing promises to improve air quality

City launches campaign to reduce air particulates by 1 percent - a tall order

Beijing's environmental watchdog has vowed to further improve air quality in the capital this year.

The city will strive to decrease its annual PM2.5 concentration, as well as its average three-year density of airborne particles, by focusing efforts on three major pollution culprits - diesel-powered trucks, kicked-up dust and volatile organic compounds - the Beijing Ecological Environment Bureau said on Tuesday.
