글로벌 허브공항의 탄소중립을 위한 ESG-정보시스템 거버넌스 비교사례 연구

This study explores the carbon-neutral strategies of global hub airports from an integrated Environmental, Social, and Governance (ESG) and Information Systems (IS) perspective. Adopting the ESG-IS Integrated Framework, the study conducts a comparative case-based analysis of four major airports—Incheon, Changi, Schiphol, and Heathrow—focusing on emission structures by scope, key mitigation measures, and the economic implications of cost sensitivity. The comparative analysis reveals that a substantial share of airport-related emissions (approximately 85-99 percent) originates from Scope 3 activities, suggesting structural limitations to achieving carbon neutrality through airport-level technological measures alone. The findings further indicate that differences in ESG-related data governance and IS integration are associated with variations in policy execution approaches and cost management strategies across cases. A scenario-based analysis illustrates how IS-enabled data integration may function as a buffering mechanism under external cost shocks, such as fluctuations in sustainable aviation fuel (SAF) prices. In this study, “Information Systems Integration” refers to a digital governance structure that connects ESG data collection, processing, reporting, and decision-making through standardization, automation, and real-time monitoring. By comparatively examining ESG-IS interaction patterns, this study contributes a governance-oriented perspective for understanding data-centric ESG transformation in complex infrastructure industries.
