This report explores the transition from “responsible gold” to “sustainable gold,” analyzing this core shift through multiple dimensions, including the alignment with international standards, full supply chain governance, due diligence and traceability, certification and validation, transparency enhancement, and standardised operations. It systematically examines the necessity, core components, and action recommendations for establishing a sustainable gold standard and governance framework in Hong Kong that integrates local characteristics while aligning with international standards. Through this research, we hope to provide fresh insights and inspiration for the sustainable development of Hong Kong’s gold market, and inject more Asian perspectives and inclusivity into the global gold governance framework.
