Global Trends and Strategic Insights in Green Aviation: A Comprehensive Bibliometric and SWOT Analysis (2000–2024)

Abstract

This study presents a comprehensive bibliometric analysis of green aviation research conducted between 2000 and 2024. Against the backdrop of intensifying climate concerns and a global push for decarbonization, the field of green aviation has gained significant momentum. Using data sourced from the Scopus database and visualized through VOSviewer, this study identifies key publication trends, leading countries and institutions, dominant research themes, and collaborative networks that define the domain. Findings indicate a substantial increase in research output, particularly after 2015, corresponding with major international climate agreements. The United States, China, and Germany emerge as the most prolific contributors, with institutions such as NASA, MIT, and Tsinghua University playing central roles. Research hotspots are centered on sustainable aviation fuels, electric and hydrogen propulsion systems, and environmental impact mitigation strategies, including carbon reduction and noise abatement. Co-authorship and institutional collaboration maps reveal strong transatlantic networks and growing contributions from Asia-Pacific institutions. The study also includes a SWOT analysis to assess the strategic positioning of green aviation research and offers forward-looking recommendations. This work serves as a foundational reference for researchers, policymakers, and industry stakeholders seeking to navigate and influence the evolving landscape of sustainable aviation.
