This study examines the influence of Green Transformational Leadership (GTL) and Green Commitment (GC) on Green Performance (GP), with Green IT Empowerment (GITE) as a mediating mechanism, within small and medium-sized enterprises (SMEs) in Indonesia. Grounded in sustainability and leadership theories, the research explores how environmentally oriented leadership and organizational commitment enhance technological empowerment to improve sustainability performance in SMEs operating in a developing-country context. A quantitative explanatory design was employed, with data collected through structured questionnaires from 100 respondents across ten SMEs in Gresik, East Java, selected based on their engagement in sustainability initiatives and technology-based processes. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS to evaluate both measurement and structural models. The results indicate that GTL and GC have significant positive effects on both GITE and GP, while GITE significantly mediates the relationships between leadership, commitment, and green performance outcomes. The model explains 60.8% of the variance in GITE and 64.9% of the variance in GP, demonstrating substantial explanatory power and underscoring the pivotal role of green leadership and commitment in driving environmental performance. These findings contribute to the literature on sustainable management in SMEs within emerging economies and offer strategic implications for SME leaders and policymakers to strengthen green leadership capabilities and technology-driven empowerment initiatives to enhance long-term sustainability performance.
