Abstract
Aviation industry growth has increased continuously over the years. Air transport demand continues to increase due to the reliability, time saving and efficiency. Aviation industry has impact on environment as a source of pollutant emissions. The estimation of pollutant emissions at taxi/idle, approach, climb out and take off of Carbon dioxide (CO2) and Nitrogen dioxide (NOx) at Juanda International Airport Indonesia was calculated using Advanced ICAO landing and take-off (LTO) cycle method. The CO2 emissions were 23.02 tons, 10.52 tons, 17.27 tons and 6.73 tons during taxi/idle, approach, climb out, take off respectively while NOx emissions were 0.03 tons, 0.03 tons, 0.12 tons and 0.06 tons for taxi/idle, approach, climb out and take-off respectively. Based on the results of the discussion it can be concluded that pollutant emissions and fuel consumption are positively related to amount of flight operation. The aircraft emissions affect the air quality around the vicinity of airport and lead to climate change.
