For the last 10 years, Clean Air Network (CAN) has been one of the most visionary and active NGOs in advocating for policies to clean up the air in Hong Kong.

In CAN’s submission on the 2019 Policy Address, we have identified seven key themes, including the need for a new Clean Air Plan beyond 2020, transformation of franchised bus fleet to electric, extension of low emission zones, strengthening control over ship emission, ozone and non-road emission source, and upgrade of our air pollution monitoring and reporting system.

In the following paragraph, we highlight the below policy areas which need budgetary support as a recommendation for Financial Secretary.

Summary of key recommendations

1) Accelerate transformation to zero (exhaust) emission mobility –

a/ Revitalize the role of the Steering Committee on the Promotion of Electric Vehicle;

4) Strengthen regional efforts to minimize Ozone –

5) Enhance preventive measures to improve public health –

a/ Extend the scope of the NCD Strategy to cover environment risk factors;
