Abstract: Due to the impact of COVID-19, China's civil airlines face an urgent imperative: to devise strategies that reconcile their development goals with the imperative of reducing emissions. Consequently, we have developed a multi-objective model that assesses the trade-offs between mitigation efforts and developmental pursuits. Furthermore, we have established future recovery and development scenarios for the post-epidemic era, with a specific focus on two major Chinese civil airlines selected for comprehensive case studies. Results show that: Our model can be used as a reference for airlines when deciding to introduce aircraft types and to purchase SAF fuel, and it can also offset the impact of rapidly rising airline costs due to fuel and aircraft type prices; In the scenario of considerable development of the operational level, the optimal investment strategy of the case companies would introduce mainly two types of aircraft, the A320NEO and the B737MAX8, which account for about 28.2 percent and 32.6 percent of the proportion of the types of aircraft introduced in the year. The results of the sensitivity analysis show that the main factor affecting the use of sustainable aviation fuel (SAF) by civil aviation enterprises is the SAF supply cap. Only when the supply ceiling is increased by 90 % does the SAF usage rate change significantly with the SAF price. Finally, policy proposals are made on the use of clean fuels, the introduction of aircraft types and the resumption of the development of aviation companies.
