The idea to create CAN followed a strong public response to Civic Exchange's conference on air pollution "The Air We Breathe – a Public Health Dialogue" held in January 2009, organized by Civic Exchange and funded by the Hong Kong Jockey Club Charities Trust. 81 delegates from HK, the Mainland and around the world convened an Experts Symposium on Air Quality and Health, where the experts came from a range of disciplines, including health, atmospheric science, biochemistry, politics, economics, law, and policy. The next day, 425 members of the public gathered at the Hong Kong Convention and Exhibition Centre for a dialogue on air pollution and public health. The participants of "The Air We Breathe" felt that an organization was needed to harness the increasing groundswell of concern in Hong Kong about air pollution, in order to effect change at the highest level of government.Thus, Clean Air Network was born.
