The capital has seen 230 "blue sky" days so far this year, Du Shaozhong, deputy director of the Beijing environment protection bureau, said during an online interview at the beijing.gov.cn, the municipal government's official website.
Du said he was confident of meeting or even exceeding this year's "blue skies" goal, with only 15 days left to achieve.
He attributed the clean skies to the restructuring of coal-burning boilers in the city to gas-powered ones, and the phasing out of old, emission-high vehicles.
