Increasingly, ports require a societal license to operate, sustained access to funding, and the ability to maintain competitiveness in a rapidly evolving global maritime sector. Demonstrating sustainability performance, however, requires a robust and transparent method for assessing diverse and complex data across environmental, social, and economic dimensions. A sustainability index provides such a mechanism by offering a conceptual and mathematical framework that evaluates, normalizes, and aggregates multiple raw indicators into a single, standardized numerical score. This integrated model enables ports to measure performance consistently, benchmark progress, support informed decision-making, and communicate sustainability outcomes to stakeholders. By transforming complex datasets into actionable insights, a sustainability index enhances resource management, promotes accountability, and supports the transition toward more sustainable and competitive port operationsFulltextenPort sustainabilitySustainability IndexSustainable Resource ManagementConference Presentationn/a
