The Government has set out Hong Kong’s Air Quality Objectives (AQOs) in the Air Pollution Control Ordinance (Cap. 311), and stipulates that the AQOs shall be reviewed at least once every five years to continuously improve air quality and better safeguard public health.
The latest round of review was completed in 2023. The Government appointed a consultant and set up the AQOs Review Working Group (Working Group) and the Air Science and Health Task Force (ASHTF) to carry out the current review to explore the scope for further tightening the AQOs referencing to the WHO Global Air Quality Guidelines (AQGs) released by the World Health Organisation (WHO) in September 2021. During August to October 2023, the Government launched a two-month public consultation exercise and held two public consultation forums to solicit views.
For details about the review, please refer to the Consultation Document, Leaflet and Summary Report(Chinese Only).
