Organised by Clean Air Network and sponsored by The Hong Kong and China Gas Company Limited, Smart Move Community Engagement programme has successfully come to an end. Through interactive learning sessions, students had the chance to experience and understand more on the cause and effects of roadside pollution. It also allows students to promote what they have learnt to a broader community, outside their schools, parents and into various districts. This helps increases public awareness and establishes a healthy neighbourhood. Mrs. Choi, a representative from Clean Air Network, presented at the closing ceremony, ‘ It’s our pleasure to see a collective effort in advocating for cleaner air. As we all know, roadside pollution heavily affects us all, especially children’s health. That’s why we would like to take this opportunity to request the Government to improve the air quality through policy change at once. Most importantly we would like to ask everyone to join this movement together, encourage your friends and family drive less and pay more attention to roadside pollution. We are glad to have G.t. (Ellen Yeung) College’s 30 school leaders as our participants.’

After gaining a basic understanding on air pollution, students and teachers planned a specialised route to measure the air quality. By using the PM2.5 air monitors, they tried to identify the pollution black spots near the school environment. So that everyone could stay away from high pollution spots and minimize exposure. Thus children’s health can be protected and let students realize by walking can reduce the amount of pollutants.

Through careful observation of the school neighbourhood,  comparing the ratio of the flow of people and car numbers, students had successfully identified 3 hot spots. Which were Tiu Keng Leng bus terminal, Tiu Keng Leng MTR station and the cross-junction in front of the school. Through measuring the air quality via the PM2.5 monitors, students underwent field research and recorded air pollution data. In the end it is fair to conclude, air quality will worsen if there’s been a vehicle increase. The cross-junction in front of G.t. (Ellen Yeung) College had the highest pollution record, within just 5 minutes there were 152 vehicles passing by, causing PM2.5 concentration to increase to a staggering 17.8ug/m3. Other than PM2.5, vehicles also emit Nitrogen oxides, like Nitrogen dioxides, damaging public health.

After gaining in-depth knowledge on their school environment, students and teachers went out and tried to connect with the community. They set up booths and promoted the message of clean air by giving out educational leaflets.

In the closing ceremony, student leaders shared what they have learnt via the format of drama. So that other students could learn more about air pollution as well. Clean Air Network hopes to increase public awareness and encourage public drive less through Smart Move Engagement Programme.
