Method and system for obtaining emission and fuel consumption data

A method is presented for obtaining emission and/or fuel consumption data associated with a road segment. The method comprises the steps of - receiving (S1) at least position data from a vehicle, - determining (S2) a respective value for at least a first and a second parameter indicative for a movement of the vehicle, - storing (S3) a frequency distribution having classes for combinations of value ranges for said at least a first and a second parameter, - updating (S4) a frequency count for a class of said frequency distribution corresponding to the determined values for said at least a first and a second parameter, - repeating (S5) the previous steps - calculating (S6) an expected emission and/or fuel consumption for a typical vehicle on said road segment on the basis of an emission or fuel consumption model that indicates the emission or fuel consumption as a function of the value of the at least a first and a second parameter weighted by the relative frequencies with which said values occur in the frequency distribution.
