Development Status and Suggestions for Sustainable Aviation Biofuel

Sustainable aviation biofuel (SABF) is a promising solution for aviation emission issues, but its sustainability and related technical standards need further study. With sustainability and technical standards as critical factors, this work first reviewed the mechanism of the Carbon Offsetting and Reduction Scheme for International Aviation and its impact on China; then introduced the International Civil Aviation Organization (ICAO) SABF greenhouse gas (GHG) emission value and emission reduction calculation method, analyzed the similarities and differences between ICAO and China GHG emission reduction calculation, discussed the Chinese and international technical standards for aviation biofuel verification, briefly described the application of aviation biofuel in and outside of China; finally reviewed the main challenges for fostering aviation biofuels in China, such as imbalance between demand and supply. Some suggestions for SABF development were presented to deal with these problems, including enhancing integration between domestic and international carbon markets, accelerating the development of an aviation biofuel sustainability certification system, establishing a minimum SABF mixing ratio, etc.
