Adoption of New Air Quality Objectives by 2014
In January 2012, the Government announced the adoption of the proposed new Air Quality Objectives (AQOs), which have been drawn up with reference to recommendations of the World Health Organisation (WHO) and the practice of advanced countries, together with a package of air quality improvement measures to better protect public health.
The Government has started working on the legislative amendments with a view to tabling the Amendment Bill in the 2012-13 session of the Legislative Council. It is expected that the proposed new AQOs will take effect in 2014.
The Government will review the AQOs not less than five years and formulate the air quality improvement package accordingly.

Review of Air Quality Objectives
In 2007, the Government engaged a consultant to review Hong Kong's Air Quality Objectives (AQOs), with a view to determining new limits on air pollutants in the atmosphere that will better protect human health. To improve air quality to the new AQO level, the promulgation of the new limits was made together with a host of emission control measures. The review was completed in 2009, and details of its findings are in the final report.
A public consultation on the proposed new AQOs and emission control measures was conducted from July to November 2009. The details of the proposal are summarized in the Consultation Document and Leaflet. A Consultation Forum was also held to solicit views from the general public. Key findings of the public consultation are presented in a summary report for public information.
Existing Air Quality Objectives
The current AQOs, which were promulgated in 1987 under the Air Pollution Control Ordinance (Cap. 311) (APCO), set out the concentration limits of seven key air pollutants in the ambient air. They will be replaced by the proposed new AQOs when the new AQOs are put in force. At present, the air quality cannot fully meet the current AQOs at the roadside due to excessive vehicle emissions and at the ambient air due to the regional smog problem
