The relationship between the humble behavior of leaders and the voluntary workplace green behaviors (VWGB) of their employees is critical to affecting the overall green performance of an organization, particularly in the situation of the COVID-19 pandemic. Traditionally, most studies focus more on the importance of leadership effectiveness, but few research studies investigate the leadership approach and its psychological mechanisms that motivate voluntary positive behavior and the efficiency of the overall performance. Thus, the authors conceptualize a research model of humble leadership that investigates the impact of humble leadership on voluntary green behavior and green performance via job autonomy and the green supporting climate. To verify the research hypotheses, 692 online and in-person questionnaires were analyzed using SmartPLS-SEM. The results showed a positive association between humble leadership and green performance, and VWGB mediates this relationship. In addition, job autonomy and green supporting climate were confirmed to mediate the association of humble leadership and VWGB; and moderate the relationship between VWGB and green performance, respectively. Notably, this study is one of the few studies in the hotel sector that look at green performance through the lens of humble leadership and VWGB. [ABSTRACT FROM AUTHOR]

The impact of pro-environmental behavior on policymaking has been an exciting area of research. While the relationship between pro-environmental behavior and policymaking has been explored in numerous studies, there needs to be more synthesis on this topic. This is the first text-mining study of pro-environmental effects in which policymaking is a significant factor. In response, this study, for the first time, takes a novel approach by using text mining in R programming to analyze 30 publications from the Scopus database on pro-environmental behavior in policymaking, highlighting major research themes and prospective research areas for future investigation. Results from text mining yielded 10 topic models, which are presented with a synopsis of the published research and a list of the primary authors, as well as a posterior probability via latent Dirichlet allocation (LDA). Additionally, the study conducts a trend analysis of the top 10 journals with the highest impact factor, considering the influence of each journal's mean citation. The study offers an overview of the impacts of pro-environmental behavior in policymaking, showing the most relevant and frequently discussed themes, introduces the scientific visualization of papers published in the Scopus database, and proposes future study directions. These findings can help researchers and environmental specialists better understand how pro-environmental behavior can be fostered more effectively through policymaking. [ABSTRACT FROM AUTHOR]
