Since 2008, the Hong Kong Report on the State of Sustainable Built Environment is published every three years in parallel with the SBE Conference Series. This year, the report shares the theme of WSBE17 Hong Kong to showcase how Hong Kong is putting sustainability ideas into action. Through a series of case studies, it offers a fascinating insight into how Hong Kong is responding to the call for a more sustainable environment through innovative new practices and the integrated efforts of all stakeholders.
