Evaluating Sustainable Aviation Fuel Production Technologies A Strategic Analysis Using the WASPAS Method

Abstract

Over the past 25 years, international passenger air traffic has tripled, and this rapid growth is expected to continue for the next 25 years. While the expansion of the aviation sector brings significant economic benefits, it also poses substantial social and environmental challenges. To address these, a "sustainable aviation policy" has been proposed as a "balanced plan" that seeks to mitigate the environmental impacts of the sector's growth while acknowledging its economic advantages. However, this definition of "sustainable aviation" is contested by various organizations, and there is little agreement between non-governmental organizations and the aviation industry. Consequently, the concept of a "standard aviation policy" remains in dispute, with different parties attempting to modify it to align with their respective goals. To develop policies for sustainable aviation, competing environmental discourses have been identified and analyzed using a classification exercise supported by rhetorical, stylistic, and thematic analysis. The Analytic Hierarchy Process (AHP) is one approach used for multi-attribute decision-making that satisfies the consistency requirements of each reciprocal matrix. Recently, the "Weighted Aggregates Sum Product Assessment System" (WASPAS) has been introduced in the literature, combining the weighted product sum and basic aggregate weighting methods.
