Clean Air Student

The Clean Air Student Council (CASC) is the youth branch of Clean Air Network (CAN).

The idea was initiated in 2019 when a group of passionate students built their own air sensors and took the step to monitor the air quality in different schools through coordination with students . The council was given a name and was formally launched in 2020, in order to serve the purpose of educating students about air pollution, empowering communities, and engaging in various forms of clean air action.

The CASC currently consists of more than 20 students ages 14 to 18 from six schools The council is constantly looking for opportunities to expand in order to enlist more students from local and international schools into joining the clean air education movement.

Hong Kong Clean Air Conference

The Clean Air Student Council has consecutively hosted the Hong Kong Clean Air Conference for 3 years. The Clean Air Conference is an annual event through which students from secondary schools can participate to share the knowledge on air pollution. Every year there is different theme of the conference and students from local and international school attend to learn, listen to a variety of speakers and participate in different activities.

Hong Kong Clean Air Campaigns

Air-monitoring Campaign (AMC)
Earth Day 2021 Air-monitoring Campaign

The purpose of this initiative was to allow students to engage in a hands-on activity to actively get to know the quality of the air they breathe on a daily basis. For Earth Day 2021, students from Island School, Discovery College and St. Paul’s Co-educational College all distributed diffusion tubes to younger students from their respective schools in order to collect data in various areas around Hong Kong. These diffusion tubes reacted with nitrogen oxide, a common pollutant found at local street-level pollution, for approximately two weeks before being taken down and sent to a lab in the United Kingdom to generate results. Some students then produced a report in which they analyzed the data, mapped out geographical trends of air quality across Hong Kong, and discussed possible solutions to alleviate air pollution.

Check out this report the students came up with over the summer of 2021.
