The Action Blue Sky Campaign is an environmental campaign in Hong Kong, organised by the Environmental Protection Department, to clean up the city's air pollution. It was officially launched by Chief Executive Donald Tsang on July 25, 2006. According to a press release of the Hong Kong government, its campaign slogan in Chinese is "全城投入　為藍天打氣" (All of the city participate to fight for a blue sky), while its campaign slogan in English is "Clean Air for a Cool Hong Kong!"
