Launched by the Environment Bureau, the "Charter on External Lighting" invites owners of and responsible persons for external lighting installations to switch off lighting installations of decorative, promotional or advertising purposes which affect the outdoor environment during the preset time (i.e. 11 p.m. or midnight to 7 a.m. on the following day). It is hoped that the Charter will help to minimize light nuisance and energy wastage progressively.
