Carbon quota management system and method based on rail transit

The invention discloses a carbon quota management system and method based on rail transit, and relates to the technical field of information management, and the system comprises an emission source management module which is used for presetting an emission factor corresponding to an emission source in an operation main body and a calculation process of an emission amount, obtaining carbon emission and carbon equivalent emission of each emission source according to the emission factors and the corresponding calculation process; the carbon emission management module is used for generating a monthly carbon quota information table of each month of a year according to the carbon emission and carbon equivalent emission data, and the carbon quota information table comprises a carbon quota value, actual carbon emission and target carbon emission reduction; and the carbon emission analysis module is used for comparing the actual carbon emission of the monitored emission source with the carbon quota value to obtain an a
