Public Consultation on Review of Air Quality Objectives

Hong Kong’s prevailing Air Quality Objectives (AQOs) took effect on 1 January 2014. It is a statutory requirement to review the AQOs at least once every five years. The Environment Bureau and Environmental Protection Department embarked on the review in mid-2016 and completed the review in December 2018. We are conducting a 3-month public consultation on the findings of the AQOs review. For details, please visit the dedicated website (www.aqoreview.hk) of the public consultation or refer to the following information.
