Assessment of pollutant emissions (CO, HC and NOx) and fuel consumption of aircraft LTO cycles at Soekarno Hatta InternationalAirport is carried out for the first time. We stressed, by aircraft type, the large aircraft which represent the greatest contribution of pollutant emissions in and around this airport.Analysis is performed to precise theirmagnitude in relationship with fuel consumption. Distribution of aircraft pollutants for different operational modes (taxiing and takeoffs) is provided and comparisons are performed. Their dispersion and impact is also confirmed. To improve environmental impact of aircraft, specific guidance relevant to air navigation functions is needed. Air traffic authorities should update the existing guidance, and Indonesian government should extend a revision of the existing environmental policy. Airport operators, governmental environmental committees, airlines, air traffic managers and aircraft manufacturers should be actively engaged to assess the potential benefits of the possible solutions reducing emission impacts on communities living around this airport. Both government and aircraft operators should address actions toward greenhouse gas emission reduction from aircraft and fuel saving. Sustainability is a key issue for aviation which is united in its commitment to develop global solutions for the sustainable future of this international airport.
