Green Transformation in Sustainable Aviation book examines the environmental, economic, technological and operational transformations faced by the aviation sector in the context of sustainability and decarbonization. Increasing air traffic, tourism mobility, energy demand and carbon emissions have transformed aviation from a transport activity into a strategic field that needs to be reconsidered in relation to climate policies, regional development, infrastructure planning and business strategies. The chapters in this book address the contradictory effects of low-cost carriers on carbon footprint and sustainable tourism, the sustainability paradox in helicopter operations, the impact of sustainable aviation fuel on airline business models, the infrastructure readiness of major airports in Türkiye for zero-emission aircraft operations, and the economic constraints of aviation decarbonization from the perspective of the leisure industry. In this respect, the book highlights the tensions between environmental sustainability goals and economic growth, accessibility, operational necessities and consumer behavior in aviation. By bringing together different dimensions of sustainable aviation, this volume offers a comprehensive contribution to the literature and provides an up-to-date reference for policymakers, airline companies, airport managers, tourism stakeholders and researchers.
