The Civil Guard has taken a significant step in environmental matters by introducing Sustainable aviation fuel (SAF) on its Air Service flights, in line with its commitment to sustainability and environmental protection.
The base selected to start this implementation is Huesca: the Huesca Air Unit It becomes the first in the Corps to receive it regularly biofuel made from biomass, after passing the corresponding technical and quality checks.
What does the use of SAF offer?
The use of this biofuel is considered the main way to Decarbonization in aviation, having a potential reduction of CO2 emissions of up to 80% with respect to conventional fossil fuels, based on accumulated experience in the sector.
Applied to the operational service of Huesca, the forecast indicates that the assigned helicopter It could prevent the emission of about 140 tons of CO2 in 2026, a significant reduction in the carbon footprint of its missions.
How the implementation has been structured
The deployment is part of a collaboration protocol with Repsol Driven by the General Directorate of the Civil Guard, focused on energy efficiency and sustainability of the Air Service aircraft, including the adoption of SAF of biomass origin.
The supplied biofuel meets international quality standards and has successfully passed the tests developed in collaboration with the Air Service itself, guaranteeing its suitability for operations.
Although the use of these fuels is not a requirement for state aircraft, the Civil Guard has chosen to integrate them as part of its decarbonization and ecological transition strategy, reinforcing its commitment to cleaner operating practices.
Operational impact and next steps
The incorporation of SAF represents a milestone in the sustainable modernization of aerial resources of the Corps, while promoting its leadership in the adoption of environmentally friendly technologies within the sphere of public safety.
Looking ahead, the institution will continue evaluating and expanding the use of sustainable fuels in other air units, with the aim of reducing emissions and contributing to compliance with climate commitments at the national and international levels.
With the launch in Huesca, the successful completion of the tests, the collaboration with Repsol, and clear reduction targets—up to 80% and 140 fewer tons of CO2 in 2026—, the Civil Guard is consolidating a roadmap to extend the use of biofuels in its air missions and move towards more efficient and responsible operations.
