Build knowledge

We build knowledge and understanding among experts and the public.

  • Health impact of air pollution is no longer disputable. It is a fact backed up by different scientific studies and understood across different sectors, including policy-makers, businesses, local communities and media.
  • We changed public monitoring of PM 2.5 data. CAN was the first organization in HK to release monitoring of PM2.5 data, prompting government to also release its own real-time measurements
  • A more comprehensive system was advanced. In 2014, the official report system changed from the old Air Pollution Index (API) to the modern Air Quality Health Index (AQHI).


Collaborate strategically

We identify, connect and amplify the resources of stakeholders both in Hong Kong and worldwide. A strong network is formed.

  • Different sectors are assembled to contribute to the ongoing clean air movement. Active support, thoughts and actions are provided by academics and experts; corporates and funders; media; political affiliations; civic groups and communities.

Advocate solutions

We work constantly to find and advocate the sustainable solutions for the future that our government can put into action today. Landmark legislations and policies are implemented with our strong lobbying.

  • A periodic review of Hong Kong’s Air Quality Objectives was legislated in 2014.
  • An HKD 1.4 billion fund was established in 2013 to retire old diesel commercial vehicles to reduce roadside emissions. All pre- Euro 4 diesel commercial vehicles will be phased out by end of 2019.
  • Clean fuel switching was made mandatory in 2014 for vessels berthing in Hong Kong which reduces year-to-year sulphur dioxide levels by up to 40%.
  • Marine vessels entering Pearl River Delta waters will be required to switch to cleaner fuel starting from 2019.
  • A full subsidized replacement scheme of toxic catalytic converters on LPG taxis/minibuses was in place (completed in 2014).
