This paper discusses the role of human resource management (HRM) in sustainable development. With the increasing global attention to environmental, social and economic sustainability issues, human resource management (HRM), as one of the core functions within organisations, plays a crucial role in driving organisations to achieve the goal of sustainable development. The article firstly describes the core functions and concepts of HRM and analyses the needs of HRM for sustainable development strategies. Then, the role of HRM in sustainable development is explored in detail from the three dimensions of environmental sustainability, social sustainability and economic sustainability. Through case studies and discussion of challenges and strategies, this paper aims to provide theoretical support and practical guidance for the practice of HRM in sustainable development.
