Air Pollution
   

In this section, you will find solid experience from different industry sectors in addressing air pollution problem in Hong Kong and the Pearl River Delta (PRD). As we look towards the future of Hong Kong as a sustainable city, air quality will become increasingly important as will the need to balance economic development with sustainable living.

These case studies illustrate a wide range of measures that can tackle air pollution at practical level. In developing these case studies, the intention is not for this to be a oneoff piece of work but rather for the examples to expand with more companies getting involved either through adopting the technologies or proposing new technologies.
