This Project aims at fostering sustainability leadership and collaboration in the business sector in Hong Kong through a partnership between big corporates and small and medium enterprises (SMEs). The partnership is constitutive of (1) a Knowledge Inventory which facilitates knowledge documentation, dissemination and exchange among businesses, large and small, and between academics and practitioners of sustainability, and (2) a Collaborative Leadership Scheme through which sustainability leaders in big corporates work closely with SMEs to build a talent pool of sustainability leaders for the business sector. This partnership will benefit SMEs in Hong Kong and the Greater Bay Area by enhancing their capacity to adopt sustainability solutions in their operation and, hence, to create shared values. By exercising sustainability leadership and actively engaging SMEs with sustainability commitments in their supply chains, big corporates can better achieve their sustainability visions and enhance their value chains. All these efforts and impacts will coalesce to build a more vibrant business sector ready to contribute to creating a sustainable society. The Project is supported by HSBC with a grant of HKD $13 million.
