Clean Air Network is pleased to announce the launch of its campaign, “Clean up the air one signature at a time”, TODAY. The slogan refers to The Petition for Clean Air which continues to be the centerpiece of CAN’s public messaging. We chose to focalize attention on a petition for two reasons: first, signing a petition is something a member of the public can do; second, this is a concrete deliverable that can be handed to the Hong Kong Government. Air pollution is not like climate change: the primary driver of better air quality is government policy, not behavioral change or reduction of energy consumption by the individual. Thanks to the support of Hong Kong’s largest shopping mall owner, The Link, for its generous sponsorship of outdoor advertising space to promote this campaign. * The featured photo was taken outside the Lung Cheung Centre, Wong Tai Sin.
