Abstract. This study aims to develop a reproducible approach to the comprehensive assessment of the economic, environmental, and operational performance of green logistics projects in aviation and to demonstrate its application using an illustrative scenario considered in the context of Kazakhstan. The information base comprises official documents of the International Air Transport Association (IATA), the International Civil Aviation Organization (ICAO), the Bureau of National Statistics of the Republic of Kazakhstan, and the Aviation Administration of Kazakhstan, as well as regulatory legal acts and peer-reviewed scientific publications. The methodology includes the calculation of net present value (NPV), the assessment of life-cycle greenhouse gas emission reductions, the measurement of operational performance, the target-based normalization of individual indicators, and their aggregation using predefined weights. A system of eight key performance indicators (KPIs) is proposed for monitoring purposes. Three aggregated outcomes—economic, environmental, and operational—are used to construct the illustrative composite index. In the scenario calculation for a hypothetical air carrier, a 2% reduction in fuel consumption, a 5% share of sustainable aviation fuel (SAF), and an assumed 65% reduction in the life-cycle emissions of SAF resulted in a 5.19% reduction in emissions, an NPV of USD 3.24 million, and a 6.67% reduction in the average flight–ground cycle time. With equal weights, the composite index was 0.740. Across the four weighting schemes considered, the index ranged from 0.713 to 0.778. The sensitivity analysis of NPV to the SAF price premium indicated a break-even threshold of approximately USD 483 per tonne, with all other parameters held constant. The scientific novelty of the study lies in adapting the composite indicator methodology to the preliminary screening of green aviation logistics projects. The study is limited by the scenario-based rather than corporate nature of the input data; therefore, the actual effectiveness of implementation must subsequently be validated using verified data from a specific airline or airport.
