| Abstract | ||
| Port activities raise growing global environmental concerns due to substantial emissions and resource use. Increasing regulatory pressures and stakeholder expectations have amplified the need for ports to integrate sustainability into supply chain operations. Port Supply Chain Integration (PSCI) is posited as a strategic approach to help ports mitigate these impacts by enhancing efficiency and coordination, thereby reducing emissions. Drawing on Stakeholder Theory, this study investigates the impact of PSCI on Port Environmental Sustainability Performance (PENSP) and examines Environmental Uncertainty (EU) as a moderating factor. Utilizing Structural Equation Modeling (SEM) on survey data from 164 maritime professionals in Egypt including individuals affiliated with port authorities, shipping companies, logistics providers, government agencies, consulting firms, and other maritime-related organizations, the analysis reveals that PSCI dimensions are significantly positively related to PENSP, while EU weakens these positive effects. The findings indicate that greater integration across port supply chains can indeed improve environmental outcomes, extending the application of Stakeholder Theory in maritime logistics. However, a clear gap remains in understanding how PSCI’s environmental benefits manifest under uncertain conditions – a gap this research begins to address by focusing on the environmental pillar of sustainability under varying external uncertainties. | ||
