Civil Aviation is one of the most growing up industries around the world, which consumes large amounts of fossil fuel in its various operations such as takeoff, landing, power generation and each other ground services. This makes determination of emissions inventory from its sources for airports transaction very important to determine the effects of gaseous emissions and airport footprint.
One of those airports is Cairo International Airport which is the major airport in Egypt and is going on to expand its operations and strategic plans aiming to become a large hub airport in the Middle East.
This paper is calculating the emissions from the Airport sources (Aircraft movement, ground services, landside traffic and secondary power generators) by using the mathematical calculation for their emission factor.
It was found that the most affected area is the area near runway end 05C which is near to Nasr city district and there are high traffic movements in comparison to the total passenger movement which is around77624 movement/year, and this number represents 52.8% of the total LTO Cycles in the airport. This makes it the most polluted area; thus, there is a need to redistribute the movements between the runways 05C, 05L and 05R.The traffic movements (245,000 vehicle/day) is very high in comparison to the total passenger movements which is 16 Million passenger/Year (about 43,836 passenger/day), this makes the underground an effective environmental control measure
