Reshaping the Environmental Image by Eliminating Silos in Sustainability Practices: A Cross‐Country Comparison

ABSTRACT Grounded in the natural resource‐based view (NRBV) theory, this study compares the impact of green transformational leadership (GTL) on promoting green innovation (GI), specifically through the mediating roles of green environmental orientation (GEO) and green dynamic capability (GDC) within the hospitality sector. Additionally, the study examines the influence of GI on environmental performance (EP) and corporate green image (CGI). A cross‐country comparison was conducted in Italy and the United States to assess the effectiveness of the theoretical framework. Smart‐PLS 4.0 was employed in conjunction with multigroup analysis to ensure the robustness and comprehensiveness of the study results, utilising time‐lagged data to enhance the validity of our findings. The results have substantial effects in both countries, and the study also found a partial mediating effect. The research makes significant contributions in three key areas. First, it presents an innovative cross‐national model that demonstrates how green leadership enhances sustainability through GI. Second, it provides a practical framework for implementing the Sustainable Development Goals (SDGs) within the luxury hotel sector. Third, it offers robust time‐lagged data that validate these relationships across diverse cultural contexts.
