The invention discloses a carbon emission reduction method for producing biological aviation kerosene by using grease waste, and relates to the field of grease waste oil reutilization and the technical field of green hydrogen emission reduction effect. Comprising the steps that firstly, grease waste is subjected to the impurity removal process, and the impurity removal process at least comprises the steps of filtering, dewatering and the like to obtain biomass refined oil; then the refined oil is subjected to a two-stage hydrogenation reaction, in the first stage, n-alkanes are generated through a hydrofining process, and light hydrocarbons and heavy hydrocarbons are obtained after the n-alkanes are subjected to fractionation; in the second stage, the light hydrocarbon and the heavy hydrocarbon are subjected to a second-stage hydrocracking isomerization reaction, and then fractionation is performed to obtain the biological aviation kerosene. In the production process, waste water generated by impurity removal
