Thai Airways has developed and replaced its in-flight equipment to be more eco-friendly, such as food containers made from biodegradable materials. These technologies will be projected to economy class passengers as a complimentary gift, allowing them to take them home and reuse them.

Thai Airways places significant importance on reducing waste by reprocessing natural materials instead of discarding these materials to help convert future items into the production process. The company has implemented various projects to support this initiative, for example, the "Tumbler Glass Product from Recycled Stainless Steel" project.

Thai Airways provides a pre-selected meal service for business class passengers and economy class passengers who hold full-fare international tickets. This service allows eligible passengers to choose their meals in advance from a set menu.
In addition, first-class passengers have access to the à la carte inflight meal service. This service offers an expanded selection of meal options, including fine menu choices beyond the standard menu available for other passengers.
These services ensure a more personalized dining experience for the class travelers.

The ecosystem is a structural relationship between living organisms and the environment in which they live together interdependently. Maintaining the equilibrium of the ecosystem will ensure their survival and therefore environmental protection and restoration is the key responsibility to which THAI, as an environmentally friendly airline, is committed. As a result, THAI has continued to create greater awareness and understanding of the importance of environmental conservation through organized activities and projects “THAI Returns Life to the Land.”

Thai Airways International maintains a diverse and well-balanced fleet as part of its ongoing fleet modernization strategy, designed to support evolving network demands while enhancing operational efficiency.

As of 2025, Thai Airways has an average age of approximately 10.7 years, reflecting a continued transition toward a younger and more efficient fleet profile. This metric is calculated based on aircraft under both owned and leased portfolios.

The fleet comprises a mix of next-generation and existing aircraft, including A320-200, A321neo, A330-300, A350-900, Boeing 777-200ER, 777-300ER, 787-8 และ Boeing 787-9 enabling the Company to efficiently serve both regional and long-haul markets while progressively improving fuel efficiency and environmental performance.

Through its fleet modernization program, the Company continues to optimize its fleet structure through disciplined capital allocation, including fleet renewal, lease portfolio management, and redelivery planning. These efforts aim to enhance passenger experience through modern cabin products and technology, while improving cost efficiency and supporting the Company’s long-term sustainability objectives.

On December 13, 2019, Thai Airways collaborated with PTT Oil and Retail Business Public Company Limited in promoting the carbon offset initiative with sustainable aviation fuels and a carbon offset program. Thai Airlines piloted this project on flights from Bangkok to Stockholm, and its first test flights on December 13 were completed with the use of sustainable aviation fuels.
Additionally, it can be blended with current fossil fuels at an increasingly commercial-scale standard under the International Civil Aviation Organization (ICAO) and the European Fuel Transport Association.
Thai Airlines also supports the European Union’s framework for progressively increasing SAF blending ratios in future batch imports from European suppliers.
Thai Airways is committed to preserving the environment for sustainable growth in the future through proactive measures that will be gradually implemented in years to come.

The Route Optimization project was initiated and implemented to reduce flight operation costs, specifically fuel expenses and carbon footprints. The Thai Airways Flight Planning System (TAFS) is used as a tool to prepare supporting flight documents for pilots, ensuring system safety and reducing fuel consumption. The system is utilized for flight planning by the Flight Dispatch Department.

Thai Airways has placed special emphasis on fuel efficiency while minimizing aircraft emissions. Many strategic measures were established to reduce energy consumption, which are to be implemented to enhance fuel flight optimization such as emission neutral flight on Thai Airlines.
This project has a net final future impact on Thai Airlines, and in 2023, the company was able to reduce aircraft fuel consumption by approximately 171,339 tons of CO2.

At the 39th Assembly of the International Civil Aviation Organization (ICAO), a resolution was adopted to implement the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) as a global measure to offset and reduce carbon dioxide emissions from international aviation. Under this framework, the civil aviation authority of each country is designated as the regulatory body responsible for overseeing and ensuring compliance with the scheme.

In Thailand, the Civil Aviation Authority of Thailand (CAAT) has prepared for the implementation of CORSIA by requiring airlines to appoint responsible representatives, prepare and submit an Emission Monitoring Plan, and submit Annual Emission Reports in accordance with the prescribed requirements.

The Company began preparing carbon dioxide emission reports under the CORSIA framework in 2019 and has continuously submitted such reports to the Civil Aviation Authority of Thailand in compliance with the applicable requirements, thereby supporting efforts to mitigate climate change impacts arising from international aviation.

Year	Total CO2 emissions from international flights (in tonnes):	Total number of international flights during reporting period:
2019	7,235,337	63,303
2020	1,730,038	14,987
2021	750,865	6,913
2022	2,837,600	24,101
2023	4,186,721	40,243
2024	5,177,006	59,817
2025	5,577,205	62,941

 

In addition, the Company has complied with the requirements of the European Union Emissions Trading System (EU ETS) by preparing and submitting carbon dioxide emissions reports and carbon credit usage reports to the German Emissions Trading Authority (DEHSt), the regulatory authority of Germany, since 2012, in full compliance with the EU ETS requirements.

These actions reflect the Company’s strong commitment to adhering to international environmental standards and regulations, while effectively managing greenhouse gas emissions to support long-term sustainable growth objectives.
