Sustainable Aviation Fuel （SAF） is considered one of the most promising new energy solutions for achieving net-negative carbon emissions in the aviation sector in the near to medium term. Currently， the International Civil Aviation Organization （ICAO） is actively promoting the development of SAF， with countries and international organizations such as the United States and the European Union formulating corresponding technology roadmaps and committing to development targets. However， SAF remains in its early stages of development and particularly in developing countries， faces multiple challenges， including issues related to feedstock supply， difficulties in large-scale production， aviation fuel safety standards， and sustainability certification， all of which contribute to the relatively high cost of SAF products. In response to these challenges， this paper proposes strategic directions for the future development of SAF and emphasizes the improvement of feedstock supply chains and processing technologies. Based on systemic safety perspectives， it advocates innovation in safety certification standards， and recommends the refinement of sustainability certification systems and standards. The goal is to achieve coordinated development across the entire SAF industry chain and provide suggestions from the perspective of aero-engine compatibility to accelerate the high-quality development of the SAF industry in China.
