128 O N E R E P O R T 2 0 2 2 OVERVIEW BUSINESS OVERVIEW AND PERFORMANCE CORPORATE GOVERNANCE FINANCIAL INFORMATION SUSTAINABLE BUSINESS DEVELOPMENT Our fleet renewal plan will see the replacement of all existing A320 aircraft with the A321neo model by 2035. In keeping with AirAsia’s practice of maintaining a single-class seating layout, each A321neo will be fitted with 236 seats, thereby increasing capacity while lowering per seat costs and emissions by up to 20%, alongside reduced NOx, and noise levels. The delivery of our next A321neo will resume in 2024, to add to the current two A321neo aircraft currently in service in Thai AirAsia. This year, we also upgraded the software of 12 aircraft as part of our efforts to continuously improve the performance of the fleet. As part of AAAGL, we are also closely monitoring developments in zero emission aircraft technology to take our decarbonisation efforts beyond 2035. In 2022, AAAGL was briefed on Airbus’ plans to develop a hydrogen-powered commercial jet aircraft by 2035. AAAGL has also signed a letter of support with ZeAero, a UK-based company invested in developing zero-emission aircraft. Operational Eco-Efficiency Thai AirAsia’s fuel efficiency programme underpins our emissions reduction efforts. We maintain some of the lowest carbon intensity measures in the industry through continuous efforts to reduce fuel consumption, both to lower our operational costs and carbon footprint. In 2022, Thai AirAsia’s CO2 emissions per available seat kilometre dropped by 5.6%, both as a result of high compliance rates in applying fuel-efficiency measures and an increase in average flight length 60 70 64.9 64.2 85.9 89.9 101.2 83.3 80 90 100 110 2017 2018 2019 2020 2021 2022 Carbon Intensity (gCO2/RPK) CO2 emissions per revenue passenger kilometre (Carbon Intensity Ratio) due to the recovery of our international flight network. Our CO2 emissions per revenue passenger kilometre (Carbon Intensity Ratio) measure also saw a sharp reversal of the upward trend of the last few years to a level approaching that of 2019 as a result of improving load factors.
