Carbon emission calculation method and system in municipal infrastructure construction stage

The invention discloses a carbon emission calculation method and system in a municipal infrastructure construction stage, and relates to the field of environmental protection. The method is applied to a carbon emission monitoring platform and comprises the following steps: acquiring a driving record of a target freight vehicle in a freight route; generating a speed curve of the target freight vehicle based on the driving record; according to the speed curve, the freight route is divided into a plurality of road sections, one road section corresponds to one average speed, and one road section corresponds to one path length; matching the average speed of the first road section with a preset carbon emission index table to obtain a carbon emission index corresponding to the first road section; and according to the carbon emission index and the path length corresponding to the first road section, calculating the carbon emission of the first road section by adopting a carbon emission calculation formula.
