On 27 June, 2019, I attended the third award ceremony for the Charter on External Lighting organized by the Environment Bureau as a guest from the Council for Sustainable Development. The ceremony commends about 4 800 participants, who pledged to switch off lighting installations with decorative, promotional or advertising purposes that affect the outdoor environment during preset times to minimise nuisance and energy wastage, and to provide the public with a better environment conducive to sleep.
