Today, greenhouse gas emissions caused by human activities have led to rising global temperatures, increasing extreme weather events, and rising sea levels, posing a threat to human society and ecosystems. People are also taking some active measures to mitigate these impacts. Therefore, in order to make a positive response in the aviation industry, this paper studies how to reduce greenhouse gas emissions brought by aircraft engines under the environment of energy conservation and emission reduction, mainly from two aspects of improving large bypass ratio engines and adopting new environmentally friendly fuels. Then the two major aspects, respectively, the origin and advantages and disadvantages of their analysis, for the current needs of the theory and the problems encountered in the actual production, how to solve and apply. After synthesizing the previous studies and reorganizing the previous studies, this paper expounds these two aspects in more detail.
