The rapid growth of the global economy has intensified the role of logistics in meeting evolving societal needs but has also exacerbated environmental and sustainability challenges. This study investigates the impact of green logistics practices on sustainable performance, with a focus on both inbound and outbound logistics. The research develops a theoretical framework to explore how green logistics practices affect social, environmental, and economic performance. Using data collected from 221 firms through a structured questionnaire and analyzed via structural equation modeling (SEM), the results reveal that both inbound and outbound green logistics practices positively influence environmental, social, and economic performance. The study contributes to the literature by clarifying the distinct effects of different logistics processes and providing empirical evidence on green logistics' role in enhancing sustainability within a developing country context. This research offers valuable insights for firms and policymakers aiming to improve business performance through effective green logistics practices.
