Employee green behavior and employee sustainable behavior in relation to organizational factors in hospitality and tourism: A bibliometric analysis

This study aims to map the knowledge structure of employee green behavior and employee sustainable behavior in relation to organizational factors in hospitality and tourism. Data were retrieved from Scopus on 22 April 2026 and comprised 146 publications (143 research articles and 3 review articles) with publication years from 2017 to 2026. The study used descriptive statistics and author-keyword co-occurrence analysis with VOSviewer. After standardization, 55 of 440 keywords met the minimum occurrence threshold of two. The results show that publication output increased markedly during 2021–2025, reaching its highest level in 2025 with 42 publications. Green human resource management, corporate social responsibility, employee green behavior, and environmental performance were prominent in the keyword network, whereas terms related to leadership and green psychological mechanisms were associated with more recent average publication years. The study identifies five thematic directions that overlap in content. Employee green behavior (EGB) is more visible than employee sustainable behavior (ESB) on the keyword map, but the evidence is insufficient to claim a conceptual shift or an expansion of measurement content from EGB to ESB. The study helps clarify the knowledge structure within the selected dataset and proposes that the EGB–ESB distinction be further examined through analyses of definitions, measurement scales, and behavioral indicators.
