📋 Tender Overview
Vietjet is the airline with the lowest emissions for flights operating in Southeast Asia, according to the Flight Emissions Review 2025 report of Cirium, the worlds leading aviation data and analysis organization. Download Vietjets maintenance of the lowest emission level shows the airlines ability to optimize operations throughout the entire operation chain, from aircraft configuration, flight network organization to load management. This achievement strengthens Vietjets position in the group of leading efficient and sustainable airlines in the region. Vietjet aircraft maintain low emission levels. Results are determined according to Ciriums EmeraldSky method, using the main index CO2/ASK (Available Seat Kilometer) - a standard measure reflecting CO2 emissions per seat provided per kilometer flown. According to the report, Vietjet has an emission level of 64.5 grams of CO2/ASK, lower than Singapore Airlines (66.7 grams) and Lion Air (67.1 grams) in the same intra-Southeast Asia ranking. The ranking compares emissions levels on flights taking place entirely within the Southeast Asia region, where the nature of short and medium-haul flights makes fuel optimization more challenging. Under similar operating conditions, Vietjets maintenance of the lowest emission level shows the airlines ability to optimize operations throughout the entire operational chain, from aircraft configuration, flight network organization to load management. The new generation aircraft fleet is an important foundation to help Vietjet maintain low emission levels. The airline currently operates mainly Airbus A320 and A321 aircraft lines, including NEO versions that save about 15-20% fuel compared to the previous generation. With the average age of its fleet among the youngest in the region, Vietjet significantly optimizes fuel consumption and CO2 emissions on each flight. In parallel with fleet investment, the airline also promotes the application of technology in operations, from flight data analysis platforms such as SkyBreathe to fuel optimization cooperation programs such as SFCO2, thereby improving operational efficiency throughout the system. Previously, Vietjet was honored by AirlineRatings in the Top 7 global sustainable airlines in 2025 thanks to outstanding efforts in reducing emissions, using fuel efficiently and developing green aviation. The airline is also recognized for its ESG (environmental, social and governance) achievements in markets such as Taiwan (China).Flight Emissions Review is Ciriums annual ranking, independently evaluating the worlds 100 largest airlines based on actual operating data, allowing comparison of emissions levels between airlines by operating scale and geographical area, thereby providing a transparent reference standard for the industry.PTTRefer to moreVietjet operates nearly 3,800 flights on the occasion of April 30 - May 1.
