Good news! Research shows that HK air quality improved last year

Yesterday (Jan 5), Assistant Director of Environmental Protection Mok Wai-chuen told the media that Hong Kong's overall air quality improved last year.

The air monitoring network found levels of most pollutants, including sulphur dioxide, nitrogen dioxide, ozone, respirable suspended particulates and fine suspended particulates, dropped last year compared with 2014's figures.

The number of days with Air Quality Health Indexes at "high" or above level dropped by 9% year-on-year at general air quality monitoring stations, and dropped by 16% at roadside air quality monitoring stations.

Mr Mok said "the Government has made a continuous effort in emission reduction. A scheme was introduced to phase out 82,000 pre-Euro IV diesel commercial vehicles by the end of 2019."

Also, he mentioned that the Government required ocean-going vessels to switch to cleaner fuel while at berth last year, significantly improving the air quality in the vicinity as shown by the marked improvement in air quality recorded at the Kwai Chung air monitoring station.

Mr Mok said that "by committing to its control measures, Hong Kong will broadly meet its air quality objectives by 2020."
