Air Europa is the only Spanish airline in the global Top 5 of the most efficient airlines
Air Europa has once again been recognized as one of the world?s most advanced airlines in terms of sustainability. The EmeraldSky 2025 report, prepared by the consulting firm Cirium, ranks it fourth worldwide in emissions efficiency, awarding it the Gold category in its international ranking.
With a figure of 53.9 grams of CO? per available seat-kilometer (ASK), the company improved its figures by 0.6% compared to the previous year. This result makes it theonly Spanish airline among the top ten and also the only traditional carrier within the leading group, which is largely dominated by low-cost carriers.
Cirium?s analysis, based on actual flight operational data and applied to the world?s top 100 airlines, confirms the importance of strategic decisions regarding fleet and operations. In the case of Air Europa, its positioning is the result of a long-standing policy, supported by one of the most modern fleets in the sector, with an average age of less than ten years.
Key models include the Boeing 737 MAX and the 787 Dreamliner, the latter capable of reducing fuel consumption and emissions by up to 25% compared to aircraft in the same category. High seat density and optimized operational performance also contribute to improving efficiency indicators.
Sustained progress in decarbonization
This recognition comes after a year in which the company has strengthened its environmental strategy. Air Europa has been honored in the sustainability challenge The Aviation Challenge, promoted by the SkyTeam alliance, and continues to make progress toward its goal of reducing emissions by 30% by 2030. At the end of the last fiscal year, the reduction had already reached 23.58%.
The airline has also maintained its EMAS certification for excellence in environmental management since 2012, making it the only Spanish companySpanish company to have renewed it consecutively for more than a decade.
In the operational sphere, notable initiatives include the gradual electrification of maintenance vehicles at airports such as Madrid-Barajas and Barcelona-El Prat, as well as the increase to 87% of electric units in ground handling operations in A Coruña.
Technology and Operational Efficiency
The implementation of technological tools has been another pillar in improving results. The OptiClimb application, which optimizes the climb rate of each flight, prevented the emission of more than 10,000 tons of CO? in 2025. Added to this are the SETO (Single Engine Taxi Out) and SETI (Single Engine Taxi In) protocols, which reduce fuel consumption during ground maneuvers by using a single engine.
At the same time, Air Europa has launched new initiatives related to emissions offsetting. In collaboration with the technology company Chooose, the airline has developed a program that allows passengers to learn about the environmental impact of their flights and contribute to certified projects by purchasing carbon credits.
