The problem of allocation of fuel consumption and carbon-dioxide emissions from transport aircraft is presented. An accurate comprehensive program for transport aircraft has been developed. The
model includes a geometry deck with 12 sub-systems, a separate engine input deck with basic parameters, a data base of engine performance from independent simulation, an aerodynamics model for all flight conditions, and an operational deck. Validation of the model is discussed.  The aircraft considered are the Boeing B737-500, the Boeing B747-400, the Boeing B777-300 and the Airbus A340-300.  Parametric studies are shown in terms of flight distance,  passenger load, baggage allowance, operation with en-route stop and direct flight. Calculations of best flight range and average passenger load have been considered. Data are presented in matrix form to be used for allocation of CO2 in carbon trading schemes and for the critical evaluation of emissions from civil and commercial operations.  It is shown that emissions per passenger per n-mile range from 0.5 to 1.5 times the reference conditions, which is taken from the design range at full passenger load. It is also shown that fuel and emission savings can be achieved from optimal flight distance.
