Aiming to achieve Net Zero by 2050, Thai AirAsia has set goals to progressively intensify its environmental management policy on a yearly basis. The Company’s policies, operations and adoption of new technologies and know-how are all geared towards minimising and controlling the greenhouse gas emissions (GHG) into the atmosphere.


Net Zero Strategy

The Company continues to work towards the same short-term objective, which was set in 2022: bringing down the amount of carbon dioxide emissions per revenue passenger kilometre to 3 gCO2/RPK. In 2023 the amount of carbon dioxide emissions per revenue passenger kilometre is 71.8 gCO2/RPK, which achieves the short-term objective by decreasing 5 gCO2/RPK. Furthermore, the Company has established the following four initiatives in order to achieve its long-term goal of reaching net zero greenhouse gas emissions, or Net Zero, by 2050 includes:

Roadmap Towards Net Zero by 2050

  • Fleet Management
  • Operational Eco-Efficiency
  • Sustainable Aviation Fuels (SAF)
  • Carbon Offsetting

1. Fleet Renewal

AirAsia Group has ordered 362 Airbus A321neos to meet our fleet replacement and expansion requirements through to 2035. The aircraft has 236-single-class seating, carrying 56 more passengers than the A320s, while using approximately 15-20% less fuel. Overall, this approach will cut carbon emissions by up to 24% compared to the current A320 fleet. The newer aircraft are to be gradually incorporated starting in 2024 with plans being to receive 3-5 models each year until the entire fleet is replaced in 2035.

2. Operational Efficiency

Thai AirAsia’s fuel efficiency programme underpins our emissions reduction efforts. The Company try to maintain the lowest carbon intensity measures as much as possible through continuous efforts to reduce fuel consumption, both to lower our operational costs and carbon footprint.

In 2023, Thai AirAsia adopted the Safety Opticlimb, an artificial intelligence optimiser that provides flight crew with climb speed recommendations to reduce fuel usage during ascent to cruising altitude. OptiClimb saves fuel approximately 70 kg per flight by assessing wind speed and direction at each altitude and calculating the optimum speed in terms of minimising fuel consumption.

The Company apply over fifteen green operating procedures with the main ones mentioned below:

3. Sustainable Aviation Fuel

Adoption of Sustainable Aviation Fuel (SAF) in the place of JET A-1 fuel to further reduce carbon emissions. SAF is a biofuel that provides an alternative to fossil fuels. Appropriately proportioned usage of SAF can reduce carbon emissions by 80% compared to Jet A-1 fuel. However, due to SAF costing approximately three times that of traditional fuel options, it has yet to be significantly adopted by commercial airlines. Studying data provided by the manufacturer of the Airbus 320 aircraft, which make up the majority of the Thai AirAsia fleet, the Company found that the planes can accommodate SAF at a proportion of 50%.

AirAsia Group has set a strategy for acquiring SAF, planned consumption, and engaging with overseas suppliers. In 2023, Thai AirAsia began exploring domestic SAF partners and aviation fuel service partners to further prepare to acquire SAF and gain an overview of its production plan, distribution, and market price. The Company has engaged in periodic meetings to update progress and reports to the Board of Directors quarterly.

4. Acquisition of Carbon Offsetting Credits

In 2023, global aviation companies, including Thai AirAsia, started to return to a similar operation to that of 2019, or prior to the COVID-19 pandemic. This led to many airlines seeking carbon credits to offset their emissions to comply with the International Civil Aviation Organization (ICAO) requirement for carbon credits to be acquired if a carrier’s emissions exceed its set baseline.

In terms of cooperation with the state, Thai AirAsia participated in the Aviation Sector Climate Change Panel of the Civil Aviation Authority of Thailand (CAAT) for drafting of an aviation energy conservation and carbon emissions reduction action plan. At the same time, the Company strictly adheres to CAAT requirements and procedures, submitting reports on aircraft fuel consumption, carbon emissions, and complying with the aviation energy conservation and carbon emissions reduction action plan.

Greenhouse Gas Emission Data

Scope 1 Emissions

The disclosure of Scope 1 emissions by Thai AirAsia does not include ground operations. Fuel usage for flight operations is calculated using the CORSIA Block-on, Block-off methodology. The Company evaluates GHG emissions in accordance with Thailand Greenhouse Gas Management Organization (TGO) standards and calculates emissions by referencing the ICAO standard Emission Factor. In the future, Thai AirAsia plans to upgrade its transport vehicles and parking devices to electrical operation to further reduce GHG emissions. The Company is studying the feasibility of this aspiration and consulting with future stakeholders.

Scope 2 Emissions

The disclosure of Scope 2 emissions by Thai AirAsia covers emissions associated with energy usage at its Don Mueang hub and AirAsia Academy (other hubs and stations are not included.) Evaluations and estimates of emissions are in accordance with TGO standards.

Scope 3 Emissions

Scope 3 - Category 3 fuel and energy not included in Scope 1 and 2

Scope 3 - Category 6 indirect carbon emissions from business travel and the business travel of employees and management in relation to Company affairs

The Company began tracking Scope 3 emissions in 2022. Scope 3 emissions comprise upstream jet fuel production by suppliers and employee business travel. The Company expects to include additional categories as highlighted in the GHG Protocol in the future.

Future Plans

AirAsia Group accelerated its preparations for the new CORSIA First Phase at the beginning of 2024, building on the work started the previous year. The decrease of the CORSIA emissions cap for its Member States to 85% of 2019 levels marks a substantial shift from the previous phase to the current one.

Since most industry projections indicate that the international aviation market will fully recover by 2024, AirAsia Group’s primary goal will be to maintain the Company’s competitive advantage while adhering to regulatory standards. The Company is prepared to manage expenditures associated with offsetting requirements, as well as to raise public awareness.

Prospective further developments include announcements of new partnerships to finance research and development and investments in decarbonisation strategies. Additionally, the Company will continue to strengthen its relationships with legislators and regulators so that it can be able to express Company views on recently proposed climate-related regulations that may affect aviation’s future.
