Abstract: The present invention relates to a method of calculating a carbon emission amount using transportation data and a server. The method of calculating a carbon emission amount using transportation data, according to an embodiment of the present invention, comprises: a first step in which a database collects and stores GPS information on a mobile terminal of a user who has boarded a transportation means; a second step in which a carbon emission amount calculation server calculates the carbon emission amount of the transportation means for each section of a road according to the GPS information on the basis of data stored in the database for each transportation means; and a third step in which the carbon emission amount calculation server corrects the carbon emission amount for each section according to a change in speed calculated using the GPS information of the transportation means, and provides the corrected carbon emission amount for each section to the mobile terminal.
