Havacılıkta Sürdürülebilirlik Yarışı: Avrupa'nın Öncü Havayollarının Kurumsal Sürdürülebilirlik Performanslarının CRITIC-EDAS ile Değerlendirilmesi[Sustainability Race in Aviation: Evaluation of Corporate Sustainability Performance of Europe’s Leading Airlines Using CRITIC-EDAS]

This study comparatively evaluates the corporate sustainability performance of Europe’s leading airlines across the economic, environmental, and social dimensions for the 2019-2023 period. The sample comprises Lufthansa, IAG, Air France-KLM, Turkish Airlines (THY), and SAS (Scandinavian Airlines). Methodologically, criterion weights were first computed objectively using CRITIC, after which annual performance scores and rankings were obtained with EDAS. The data were compiled from the companies’ sustainability/integrated annual reports and open-access sources, and are based on firm-level yearly indicators. The findings show that no airline simultaneously leads across all dimensions. Turkish Airlines stands out markedly in the economic dimension in the post-pandemic period; SAS consistently leads the environmental dimension throughout the period; and Air France-KLM maintains a steady first place in the social dimension. IAG demonstrates a strong recovery in the economic and social domains, while Lufthansa remains broadly balanced but positioned in the middle tier. By providing an evidence-based framework for the multidimensional measurement of sustainability performance in European aviation, the study offers concrete implications for prioritization by managers and policymakers.
