Noise and Air Pollutants As of 2021, all AirAsia aircraft are compliant with ICAO Annex 16 Chapter 4 noise standards while 85.6% of the fleet meets with the most stringent ICAO CAEP/8 NOx emissions standards1. As we phase out older aircraft in exchange for new Airbus A321neo models, we aim for 100% compliance with ICAO CAEP/8 NOx standards. Indicators 2019 2020 2021 NOx emissions (tonnes)1 2,474 725 261 NOx emissions intensity (gNOx/RPK)1 0.0390 0.0508 0.0629 SOx emissions (tonnes)2 271 79 29 Volatile Organic Compounds (VOC) emissions (kg)2 936,957 274,492 98,752 1 NOx emissions and compliance data are obtained from the ICAO Emissions Bank issue 28C dated 20 July 2021. The NOx emissions value per landing and takeoff (LTO) cycle is based on the weighted average of AirAsia’s fleet composition as of FY2021. 2 According to the US EPA, SO2 represents the highest composition of SOx emissions, hence SO2 is considered as SOx for the purpose of calculations. SO2 and VOC emissions data are sourced from US EPA’s Generic Aircraft Type Emission Factors table. Scope 2 Emissions Capital A’s Scope 2 disclosures cover emissions associated with energy consumption at all our facilities and offices.
