Policy Change

Under our ongoing advocacy work, the Government has in the past years:

• Amended the principal air pollution control ordinance to review Air Quality Objectives at least once every five years
• Set up a 10–billion dollar fund to subsidize the replacement of old and polluting commercial diesel vehicles
• Mandated fuel switch at berth for ocean going vessels
• Commenced the first walkability study in Hong Kong
• Published the Clean Air Plan 2035 and the first EV Roadmap for Hong Kong, which
• Set out long-term strategy on air quality management and green transport

And the Government will

• Enhance air quality at public transport interchanges
• Update the Air Quality Health Index to show long-term and short-term health risks
• Commit to provide more detailed district–based air quality information to public

Knowledge Change

In the past 5 years, CAN has:

• Approached more than 20,000 individuals, including over 2,000 students in 100 secondary schools, more than 500 parents and volunteers, through our public empowerment programmes
• Maintained a strong local media presence

Now, the public understands a lot more about the health impacts of air pollution!

Air Pollution Reduced

Over the past 5 years, the annual average concentrations of major pollutants have been dropping:

Societal Costs of Air Pollution Reduced

In the past 5 years,

• Number of premature deaths dropped by 29%
• Economic loss dropped by 30%
• Number of Clean Air Days increased by 37%

Current Actions: 

• Advocating for medium–term green transport policies
• Furthering our educational programmes
• Building and sharing knowledge to address needs of schools, families, patients and communities

Future Plans: 

• Accelerate Hong Kong’s transition of franchised bus, public light bus and heavy–duty goods vehicles to zero–emission modes, in alignment with the Government’s 2025 Strategic Plan
• Become the top environmental educational partner of secondary and primary schools in Hong Kong
• Explore more stringent indoor air quality standard for schools, elderly centers and public buildings in Hong Kong

In 2013, the International Agency for Research on Cancer (IARC) of the World Health Organization classified outdoor air pollution as group 1 carcinogen. This is the first time that scientists evaluated the air people breathe for its cancer-causing potential.

Comprehensive analysis finds air pollution may be damaging every organ in the body, causing dementia, heart and lung diseases, fertility problems and reduced intelligence.

Two major local studies published in 2008 (HKU-CUHK) and 2018 (HKU-Cambridge) found that the socially deprived is exposed to more air pollution in Hong Kong. Although all individuals are exposed to some level of air pollution, those who are already in poor health and those who are socially disadvantaged are most strongly affected.

Air pollution particles have been found on the foetal side of placentas, indicating that unborn babies are directly exposed to the black carbon produced by motor traffic and fuel burning.
