This study investigates the baseline carbon footprint of an airport. Approximately 1,470,530 tons of CO2 equivalent (e) emissions are generated by this airport annually. Aircrafts, ground access to airport, waste disposal, energy usage, airside vehicles, de-icer usage and wastewater processing are the contributors. As expected, aircrafts have the highest share in total greenhouse emissions. Ground access to airport, indicating how to reach the airport by ground transportation vehicles for passengers, employees, cargo etc. accounts for 11% of the total emissions. CO2 emissions that originate from sources under the control of the airport authorities, are only 4% of the total emissions mentioned. Nevertheless, airport operators must lower these emissions by taking necessary precautions. Total CO2 e emissions generated by the airport showed a 55% increase within three years. On the other hand, obtained figures show a slightly decreasing trend for kg CO2 e emissions per passenger.
