Abstract: With the further intensification of global warming, the international aviation industry is facing more urgent carbon emission reduction requirements. Promoting the usage of sustainable aviation fuel (SAF) could effectively meet the requirements of carbon emission reduction without significant change on the current civil aviation fuel supply system. It would be the most effective way to achieve carbon emission reduction in the short and medium term. This paper briefly introduces the certified SAF process route and its technical characteristics on a global scale and the current development status of China's SAF industry. additionally,this paper points out that the potential challenges faced by China's SAF industry at the production end, policy support end, and transportation and utilization end. There are some problems in China's SAF industry, such as uncertain raw material supply, insufficient policy support,restrictions on the transportation and utilization of SAF. Relevant suggestions and measures have been put forward.
