Text mining on sustainability reports of top 40 airlines and bibliometric analysis of airline's sustainability

Abstract

This study aims to comprehensively explore sustainability practices, guidelines, and emerging trends in the airline industry through an in-depth analysis of their sustainability reviews. A thorough bibliometric analysis of airline sustainability was conducted using the Scopus Database. Additionally, employing text-mining techniques, a meticulous analysis focused on the sustainability reports of the leading 20 airlines compared to the subsequent 20, considered as followers, in the textual examination of sustainability reports. The results revealed thematic disparities between these two cohorts. The top 20 airlines prioritized significant concerns such as safety and other sustainability-related aspects like biodiversity. In contrast, follower companies placed a higher emphasis on financial considerations. This analysis illuminates the primary focuses of airlines and the spectrum of sustainability-related issues. Moreover, offering valuable insights for both researchers and industry practitioners, this study presents a repository of pertinent data related to sustainability practices in the aviation sector. Integrating text mining and bibliometric analysis emphasizes essential facets of airline sustainability, resulting in a comprehensive overview of the research landscape.
