9. Selection of Sustainable Aviation Fuels: An Expert-Based Comparative Approach

Sustainable aviation fuels (SAFs) play a vital role in achieving global carbon neutrality and mitigating the environmental impact of aviation. However, selecting the optimal SAF alternative necessitates a comprehensive assessment of economic, technical, and social considerations. To address this, a multi-criteria decision-making (MCDM) approach employing the analytical hierarchy process (AHP) method was used. Seventeen international aviation experts, comprising both experienced and less-experienced individuals, participated in this study. AHP facilitated the prioritization of factors based on their relative significance, enabling well-informed decision-making that reconciles divergent stakeholder objectives. The evaluation outcomes emphasize the utmost importance of environmental impact criteria, followed by economic and technical feasibility. These insights are invaluable for policymakers and decision-makers in identifying the most suitable SAF alternative aligned with their specific goals and objectives.
