["Corporate Social Responsibility and Environmental Management, EarlyView. ", "\nABSTRACT\nThis study examines how Green Inclusive Leadership (GIL) enhances Team Green Innovation Performance (TGIP) in Sierra Leone's mining sector. Drawing on Self‐Determination Theory and Situational Strength Theory, we propose a moderated mediation model in which Green Harmonious Passion (GHP) mediates the GIL–TGIP relationship, while Perceived Organizational Support for the Environment (POSE) moderates the leadership–passion link. Using multi‐wave data from 305 employees and supervisors across 68 teams, PLS‐SEM results show that GIL positively predicts TGIP, and GHP partially mediates this relationship. Moreover, POSE strengthens both the GIL–GHP link and the indirect effect on TGIP. The findings advance green leadership research by integrating motivational and contextual mechanisms driving sustainable innovation in developing economies.\n"]
