This study examines how green horizontal leadership impacts the performance of green projects, emphasizing the mediating roles of green proactive innovation and green reactive innovation. This study investigates the role of leadership in fostering innovation and enhancing sustainability outcomes through the application of stewardship theory, organizational learning theory, and the resource-based view (RBV). A quantitative survey was conducted among enterprises in Jiangsu Province, China, a region noted for its industrial and economic development alongside its increasing environmental initiatives. Leadership, innovation, and project performance were examined using structural equation modeling. Green horizontal leadership promotes green project performance by mediating proactive and reactive innovation. Participatory and decentralized leadership styles improve environmental outcomes through strategic and compliance-focused sustainability programs. Merging multiple views, the study provides theoretical insights into leadership and environmental sustainability success. Organizations seeking sustainability through leadership development, investment in green innovations, and flexible laws have demonstrable results. Future research will expand the study's geographic coverage and examine other mediating factors that affect leadership, innovation, and performance.</p> Saqib Altaf Li Wenyuan Nasira Altaf Muhammad Kamran Siddiqui Muhammad Shahbaz Copyright (c) 2025 2025-04-28 2025-04-28 18 2 29 41 10.55217/103.v18i2.920
