Doha, Qatar: Qatar Airways has been recognized as the world’s most emission-efficient large carrier, according to the recently released 2025 EmeraldSky Annual Review by Cirium. The airline's performance is highlighted by its low carbon dioxide emissions per available seat kilometre, underscoring its operational efficiency and environmental responsibility.
The review evaluates the environmental performance of the largest global airlines, using a benchmark that compares emissions relative to available seat kilometres. Qatar Airways achieved an emissions intensity of approximately 60 grams of CO2 per passenger kilometre, one of the lowest among the world's major airlines. This achievement is attributed to its modern fleet, extensive long-haul network, and numerous fuel-saving initiatives.
Through the adoption of next-generation aircraft such as the Airbus A350 and Boeing 787, Qatar Airways continues to reduce fuel consumption and emissions. The airline also supports broader sustainability goals, including the increased use of sustainable aviation fuel and the industry's net-zero emissions target by 2050.
Industry experts note that fleet composition, seat density, and route optimization are critical factors in achieving high environmental efficiency. Qatar Airways' efforts to renew its fleet and optimize operational processes have allowed it to outperform many of its competitors, including other full-service carriers. Additionally, Singapore-based Scoot was named the most emissions-efficient airline overall in the 2025 review, while Qatar Airways leads among the largest carriers. This recognition reflects the airline’s commitment to sustainable growth and operational excellence in aviation.
