Analysis of Fuel Consumption and Emissions Produced by Aircraft at Indonesian Airports

Abstract

Indonesia recorded the largest aviation market in Southeast Asia in December 2022 with 9.6 million seats available. This represents a 69% growth compared to the same period in 2019 before the pandemic, driven by an increase in domestic routes with the top 10 busiest airports in Southeast Asia. The increase in flight demand creates operational costs for airlines. Fuel when flying will also emit a lot of emissions so the airline is also obliged to pay a carbon fee (CO2) covering the environmental costs of emissions. The purpose of this study is to understand the impact of flight time on fuel consumption and the resulting emission burden at Indonesian Airports. The method used to calculate fuel is using the calculation of Horonjeff et al., (2010) and for the calculation of emissions using the "Carbon Emissions Calculator Methodology". Sultan Hasanuddin Airport has the largest difference in fuel and emissions compared to other airports. The importance of actual flight time in increasing emissions can be used as an indicator of airline fuel efficiency. In addition, the results of this study can provide a reference for related parties to develop more efficient methods of fuel use, so as to reduce aviation fuel costs.
