Aircraft aviation fuel combustion is a major contributor to carbon emissions in the civil aviation industry, the most efficient approach to abate carbon in this industry is to use sustainable aviation fuel (SAF). However, the suppressive market atmosphere for the new SAF industry and the issues from production are severely limiting its scale usage. This paper starts from the current situation of SAF, with the qualitative study of its current data and provides methods for its large-scale use. This passage discovers a widespread neglect of civil aviation carbon emissions, people have just gotten started in replacement fuel exploration, which is located at the detrimental position of the investment curve. So the article interprets the existing hindering factors of SAF through price analysis, investment curve analysis and market incentive policy, then proposes the path of SAF from the selection of raw material extraction, adaptation to market incentive environment and potential development of synthesis technology according to the existing issues. Consequently, the proper exploitation of SAF needs multiple stimuli from both markets and policies, which can lead to a long-term prospective elimination of carbon emissions in the civic aviation industry.
