• In 2025, operational improvements saved 4,200 tonnes of fuel and reduced distance flown by 711,000 kilometres—the equivalent of 18 trips around the world
• The emissions avoided are equivalent to taking nearly 3,000 vehicles off the road, or to the carbon absorbed by more than 600,000 trees
On World Environment Day, ENAIRE is reaffirming its commitment to sustainability through its management of Spanish airspace, which is making a decisive contribution to decarbonising the aviation sector.
In 2025, Spain’s national air navigation service provider cut aviation CO2 emissions to the atmosphere by 13,300 tonnes, after handling 2.47 million flights, up 4.7% on 2024 and marking a new all-time high.
Operational improvements designed to deliver more direct and efficient flight paths also enabled airlines to save 4,200 tonnes of fuel and reduce distance flown by 711,000 kilometres—the equivalent of roughly 18 trips around the world.
By promoting efficiency and more sustainable airspace management, ENAIRE has helped airlines operate more efficiently. The emissions avoided are equivalent to taking nearly 3,000 vehicles off the road, or to the amount of CO2 absorbed by more than 600,000 trees.
Flight efficiency also improved, reaching 96.8%, while landing and take-off efficiency also improved, with an average of 39% of operations authorised in continuous descent and 76% in continuous climb. Digitalisation and more efficient use of resources also cut paper consumption by 40%.
Five strategic plans
As an organisation committed to protecting the planet, ENAIRE pursues its mission through five plans set out in its Strategic Plan, Flight Plan 2030, which together shape the organisation’s overall strategy for minimising its environmental impact and contributing to the decarbonisation of air transport.
Together, these five plans provide a comprehensive framework and are all closely linked to environmental protection: Fly Clean, focused on operational efficiency; Fly Quiet, aimed at mitigating noise impact; Eco-ENAIRE, designed to promote energy efficiency, renewable energy and sustainable consumption; Green Commitment, focused on achieving excellence in environmental management; and Environmental Responsibility, aimed at the proactive management of projects through the reduction and continuous monitoring of their environmental impact.
In terms of sustainable mobility, electric vehicles now account for 53% of ENAIRE’s fleet. On renewable energy, key milestones include the commissioning of the photovoltaic plant at the Barcelona Control Centre, 100% renewable electricity supply, and 6% in-house generation.
Under its Noise Action Plan (PAR), and in coordination with the relevant authorities, ENAIRE has also put in place measures to minimise environmental noise at airports handling more than 50,000 movements a year. This is helping to meet the European reduction targets set for 2030 under the Zero Pollution Action Plan.
About ENAIRE
ENAIRE is the air navigation service provider in Spain.
As a company of the Ministry of Sustainable Transport and Mobility, it provides air traffic control services during the en route and approach phases of all flights to and from Spain and overflights. In addition, it manages communications, navigation and surveillance services from ENAIRE in the airspace and the entire AENA airport network in Spain and provides aerodrome air traffic control services in 21 airports, including the busiest.
ENAIRE is the fourth largest European air navigation service provider, and it is a member of international partnerships A6 Alliance, SESAR (Single European Sky ATM Research) Joint Undertaking, SESAR Deployment Manager, iTEC, CANSO (Civil Air Navigation Services Organisation) and collaborates closely with ICAO (International Civil Aviation Organization).
ENAIRE has obtained the highest rating in the key performance indicator for air safety at European scale for seven consecutive years, the last six with the maximum possible score of 100%. It has also been awarded the EFQM 600 Seal for its safe, efficient, innovative and sustainable management of air navigation services.
