“Green” human resource management is a strategic approach that recognizes the relationship between environmental sustainability and human resources. This can lead to numerous benefits, including cost savings, improved employee engagement, and long-term organizational sustainability. The article examines the methodological foundations of human resource management in the context of implementing the green office concept. The purpose of the study is to identify the components of the conceptual model for implementing the policy of “green” human resource management at enterprises. The basic procedures of “green” human resource management are researched. It is identified that environmentally oriented HR initiatives can be considered as an organizational mechanism aimed at ensuring that employees behave in a “green” way. It is proved that “green” human resource management plays an important role in shaping the environmental values of employees and improving their environmental behaviour, contributing to the formation of the need to create answers to sustainable development issues in the human resource management systems of organizations. A promising direction for further research is the scientific substantiation of the list of indicators for assessing the effectiveness of the implementation of the “green” policy of an enterprise in terms of personnel management.
