In a world faced with rising challenges from climate change, PolyU has made great strides in curbing carbon emissions, in support of Hong Kong’s goal to achieve carbon neutrality by 2050. We pave the way for a sustainable future through education, research, operation, and campus development.


The University established the Campus Carbon Neutrality Committee in 2022 to drive our carbon neutrality efforts. Led by Professor Christopher Chao, Vice President (Research and Innovation), this Committee is responsible for strategic planning, development, implementation, and monitoring of our roadmap and action plans towards carbon neutrality by 2045 and for ensuring the fulfilment of short-term (2028) and medium-term (2033) targets.


In addition, the Committee has launched the Carbon Neutrality Funding Scheme since 2022/23. The Scheme supports sustainability-related research projects that leverage the University’s expertise and utilise the campus as a testbed for sustainability-related technologies and solutions to enhance living standards and reduce carbon emissions.


Recently, the Scheme has supported another nine projects in its 2023/24 exercise, covering a variety of areas as indicated in the projects below:
