The European aerospace sector is undergoing a profound regulatory transformation, driven by two mechanisms that directly alter the cost structure of airlines: the requirement to incorporate sustainable aviation fuel and the elimination of free carbon quotas. These two constraints, which recently came into effect, are reshaping industrial trade-offs well beyond just fuel costs.
Carbon Quotas and Aviation in Europe: The End of Free Allocations
Since January 1, 2026, airlines operating intra-European flights no longer benefit from any free allocations in the EU ETS system. Each ton of CO₂ emitted must now be covered by quotas purchased at auction or on the secondary market.
This removal has not been abrupt. It has followed a gradual timetable: a 25% reduction in free allocations in 2024, then a 50% reduction in 2025, before complete phase-out. The overall cap of the EU ETS continues to decrease by about 4.3 to 4.4% per year, which mechanically reduces the supply of available quotas and drives up their price.
For airlines, the effect is twofold. The direct operating cost per kilometer increases on intra-European routes, while services departing from or arriving in non-EU countries remain outside the scope. This gap creates a competitive distortion that several players in air transport in France and Europe are denouncing, without the regulatory framework providing a short-term corrective. Analyses published on airnews.net regularly detail the impact of these measures on different categories of airlines, from low-cost to long-haul.
SAF Obligation in Europe: The ReFuelEU Mandate and Its Trajectory Until 2050
The ReFuelEU regulation has mandated since 2025 that all jet fuel suppliers serving airports in the European Union incorporate at least 2% sustainable aviation fuel (SAF). This threshold may seem modest, but the trajectory is binding: 6% by 2030, 20% by 2035, and then 70% by 2050.
SAF is no longer a voluntary commitment displayed in the CSR reports of companies. It is a structural obligation, accompanied by sanctions. The European Commission has also initiated infringement procedures against thirteen member states that had not yet properly transposed the regulation into their national law.
The Supply and Cost Problem
The regulatory obligation faces an industrial reality: global SAF production remains far below projected demand. Production pathways rely on various raw materials (used oils, forestry residues, plastic waste treated by pyrolysis), but none have yet reached a sufficient scale to cover the necessary volumes.
The cost of SAF remains several times higher than that of fossil jet fuel. The Netherlands has obtained EU approval for a €335 million aid program aimed at supporting domestic SAF production. This type of subsidy illustrates a shared observation among several analysts: the European challenge is no longer to invent sustainable fuel, but to make large-scale production projects financially viable.
- The ReFuelEU mandate includes a specific sub-target for e-fuels (synthetic fuels produced from renewable electricity and captured CO₂), mandatory from 2030 via the power-to-liquid pathway.
- A reserve of 20 million EU ETS quotas is planned to partially subsidize the additional cost of SAF, creating a direct link between the carbon market and the financing of the aviation energy transition.
- Geopolitical tensions, particularly around the Strait of Hormuz, have driven SAF prices to record levels, exceeding initial projections by industry players.
Aviation Market: Growth in Passenger Traffic and Industrial Constraints at Airbus
Global air traffic continues to grow, driven by demand in Southeast Asia and the recovery of long-haul flows. Recent orders illustrate this dynamic: Vietnam Airlines has committed to five Airbus A350-900s, while Vietravel has signed for 50 aircraft from the A220 and A321neo families.
These massive orders pose a concrete problem: production rates remain limited by supply chains. Engine manufacturers, particularly those producing the LEAP-1A (engine for the A320neo), are struggling to keep up. MTU Maintenance recently secured its first LEAP-1A maintenance contracts in North Africa, indicating that the installed base of these engines is expanding faster than support capabilities.
In France, the aerospace sector remains a major industrial pillar, but the pressure on skills is hindering ramp-ups. The recruitment of commercial pilots, maintenance technicians, and systems engineers is a bottleneck that the growth in traffic only exacerbates.
Defense and Military Aviation: Fleets Under Pressure
The defense aspect of the aerospace sector is experiencing its own tensions. The French Navy has received its first two Falcon 2000 LXS Albatros, intended for maritime surveillance. This delivery marks a step in renewing an aging fleet, but the volumes remain low compared to operational needs.
On the drone side, the MQ-9A Reaper program is facing successive decisions to halt and restart. Civil drones remain overshadowed by military drones in terms of funding and regulatory framework, despite a growing potential for use in logistics and infrastructure inspection.
The helicopters of the National Gendarmerie are described as being close to capacity breaking point, a warning signal regarding the overall state of French state fleets. Poland, for its part, is establishing itself as a major market for defense manufacturers, with technology transfers attracting players from around the world to its specialized trade shows.
The convergence of environmental constraints, supply tensions, and defense needs is reshaping the priorities of the European aerospace sector. The budgetary decisions of the coming years will determine whether Europe can maintain its industrial base while adhering to a climate trajectory that leaves no room for maneuver.
