The invention relates to the technical field of aerospace, in particular to a method and device for measuring the emission load of aircraft engine emissions. The method comprises the steps of acquiring four-dimensional data and corresponding meteorological data of an aircraft in the flight process wherein the four-dimensional data comprise longitude and latitude, height and flight time of the aircraft; based on the four-dimensional data of the aircraft, determining the fuel consumption rate of the height of the aircraft; determining an emission factor of the emissions according to the types ofthe emissions and the four-dimensional data and meteorological data of the aircraft; and according to the flight time of the aircraft, the fuel consumption rate of the height of the aircraft and theemission factor, obtaining the emission load of the engine emissions of the aircraft. The invention is more accurate in measured data, and provides a powerful data guarantee for the control of the emission load of the aircraft.
