This article examines the role of Human Resource Management (HRM) in shaping employees’ green behaviour and its contribution to organisational environmental performance through an original bibliometric analysis of the international literature. The analysis is based on 105 scientific publications retrieved from the Scopus database for the period 2009–2025. Bibliometric techniques were applied using Bibliometrix and VOSviewer to map publication trends, co-authorship networks, thematic clusters, and the maturity of research themes. The results indicate a strong increase in research output after 2019, combined with high levels of international collaboration and a geographical concentration of studies in Asian economies. Keyword co-occurrence analysis identifies Green Human Resource Management (GHRM) and organisational environmental performance as the core conceptual pillars of the field, while employees’ green behaviour emerges as a key mediating mechanism linking HR practices to environmental outcomes. Thematic mapping based on centrality and density suggests that the field has entered a phase of theoretical consolidation, with emerging research directions focusing on behavioural, strategic, and social dimensions of sustainability. Overall, the study provides a structured overview of the GHRM research landscape and highlights important gaps related to causal mechanisms, economic performance, and cross-sectoral and cross-country evidence. The findings also indicate that sectoral applications beyond tourism and hospitality, cross-country comparative studies, and the integration of economic performance indicators with GHRM remain underexplored, highlighting specific directions for future research. The study adopts a bibliometric research design and does not aim to provide a systematic review of empirical findings.
