As port authorities and cargo operators seek strategies to reduce carbon emissions while ensuring operational efficiency, some are turning to the concept of green corridors. These solutions aim to establish formalized partnerships among ports, carriers, shippers, and countries. During the process, the stakeholders must consider four priority areas (alternative fuels, bunkering infrastructure, vessel decarbonization pathways, and cargo demand dynamics) from seven angles (environmental, economic, infrastructure, regulatory, operational, technological, and social). This study explores the prioritization of these criteria for establishing a green maritime corridor between two major ports in Portugal and Angola, which would be a significant step toward promoting sustainable global trade. Utilizing the fuzzy AHP, this research analyzes all these factors and their associated sub-criteria derived from a comprehensive literature review and consultations with stakeholders from the Ports of Sines and Luanda. The findings show the dominance of environmental compatibility and economic viability, while social acceptance shows the lowest score. This framework guides the decision-making process for developing a sustainable shipping corridor. The results offer valuable insights for policymakers which can guide them in fostering resilient maritime transport routes, accelerating the adoption of decarbonization strategies and playing a critical role in achieving the IMO’s zero-emission targets by 2050.

Digital Shipping Corridors (DSCs) are gaining traction as integrated models for increasing transparency, efficiency, and sustainability in maritime logistics. Yet, the enabling conditions for their effective implementation remain insufficiently explored. This study employs a qualitative thematic review approach, analyzing the academic literature, global policy documents, and selected case studies to identify and synthesize the critical success factors for DSC development. The analysis reveals seven interdependent factors: technological infrastructure, economic feasibility, regulatory frameworks, logistical efficiency, logistical security, stakeholder collaboration, and environmental sustainability. These factors are not independent but interact dynamically, requiring coordinated development across technical, institutional, and environmental domains. This study proposes a dynamic interaction framework that illustrates how progress in one area (e.g., digital infrastructure) depends on readiness in others (e.g., governance and cross-sector collaboration). The outcomes contribute both conceptually and practically. The framework offers a system-level understanding of DSC implementation and identifies key leverage points for intervention. The findings provide strategic guidance for policymakers, port authorities, and supply chain stakeholders pursuing digitally enabled sustainable maritime corridors. This study also highlights areas for future empirical validation, particularly in relation to governance integration and cross-border alignment.
