Key Recommendation 6:
Upgrade air monitoring infrastructure and reporting mechanism
Over the years, the general public has a stronger desire to understand the health impacts of air pollution. Currently, there is a lack of community or district-based databases that measure the number of doctor visits or hospital bed days due to respiratory and circulatory disease, for example, chronic obstructive pulmonary disease (COPD), asthma, bronchitis, etc. However, it is difficult to get timely official data.
Currently, Hong Kong lags behind London, Paris, Seoul, Singapore for the density of roadside air pollution monitoring stations . There is also a lack of adequate monitoring stations at roadside/ground level that collects roadside air quality samples as well as relevant systems to report roadside air pollution statistics to community institutions. There is no indication to monitor ground level air quality of areas where vulnerable groups spend much of their time, including schools, elderly centres, hospitals or medical centres.
6.1 CAN urges the HKSAR Government, under the Smart City Blueprint, to upgrade air pollution monitoring infrastructure by setting up at least one roadside monitoring station in each of the 18 districts in Hong Kong. We also urge the HKSAR Government to improve reporting on air pollution, publicizing timely and district-based health information.
 Clean Air Network conducted a comparison of density of roadside air pollution stations among multiple cities. Population per one roadside station: London: 113,000; Paris: 150,000; Seoul: 700,000; Singapore: 1,400,000; Hong Kong: 2,433,000;
Area per one roadside station: London: 20km2; Paris: 7km2; Seoul: 43km2; Singapore: 175 km2; Hong Kong: 367km2.
