Organized and coordinated by the Urban Council, the "Keep Hong Kong Clean Campaign" was launched in 1972 with the aim to generate public concern of environmental cleanliness as the basis of civic pride.

At the beginning of the Campaign, Lap Sap Chung, a representative cartoon litterbug, was used for promotion. It quickly became a well-known figure within the community. The Campaign has been in place for more than a few decades with different focuses and slogans such as clean up the building and clean up the markets and beaches. Nowadays, the Keep Hong Kong Clean Campaign is still going strong.
