Relative sustainability analysis of global-scale airports

Abstract

The sustainability impact and reporting results of air transport have become important for societies. In this field, the Global Reporting Initiative presents the reports and databases of many sectors in chronological order. Nowadays, airports all over the world transparently present their sustainability results to the public with a sense of responsibility. In this respect measuring the sustainability performance of airports, determining the targets, and making the necessary improvements become more of an issue. In this study, the efficiency analysis of 30 international airports included in the comprehensive sustainability database of the Global Reporting Initiative was carried out using the Data Envelopment Analysis (DEA). In this context, common inputs and outputs affecting the sustainability of airports were determined and a sustainability performance measurement model was developed. The relative efficiency scores of the airports were found with the input-oriented CCR method by using the developed model. Thanks to the results, inefficient airports were identified, and necessary improvements were presented to improve sustainability levels.
