Earth Hour at HSUHK

Dear Colleagues and Students,

To continue our effort to make our campus greener and our commitment to sustainability, HSUHK has signed up for the “Earth Hour 2022”, a global event co-ordinated by the World Wide Fund for Nature (“WWF”). Around the globe, millions of people, businesses, and landmarks set aside an hour to host events, switch off their lights, and make noise for actions on climate change.

Earth Hour’s lights-out moment symbolises a commitment to change beyond the hour. This year’s theme, "Habits Protect Habitats", reminds us that our habits have a direct impact on the habitats that surround us – our actions shape the future of critically important places and therefore shape our own future.

Details of HSUHK’s participation are as follows: 


26.03.2022 (Saturday)
