Charter on External Lighting

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.

As announced in the Signing Ceremony held on 1 April 2016, PolyU has signed this Charter to show its support and has pledged to switch off non-essential external lighting installations on campus, student halls and other concerned premises during the preset times.
