PolyU Campus Sustainability Weeks is held annually to promote green living among staff and students. It returned in January 2018 and engaged over 2,000 staff and students through sharing sessions with various speakers, workshops, beach clean-up activity, food drive, and exhibition in two weeks. Participants were given the opportunity to experience an environmentally sustainable lifestyle and embark on a pathway to sustainability. The event invited dialogues and examination on different sustainability values and principles and suggested green practices that all can easily translate into our daily life.
