Airlines Press EU to Rethink Carbon Rules Amid Global Rivalry

Europe’s largest airline groups and industry bodies are stepping up calls for the European Union to revisit its carbon pricing and fuel mandates for aviation, warning that the current framework risks undermining the region’s global competitiveness just as air travel demand continues to recover.

Mounting concerns over EU ETS costs

European carriers argue that the rapid tightening of the EU Emissions Trading System for aviation is creating a cost burden that non-EU competitors do not face. Under reforms linked to the Fit for 55 climate package, free emission allowances for airlines are being phased out and coverage for flights within Europe has expanded, driving up the effective carbon price per tonne of CO₂.

Industry associations representing major European airlines state that this has translated into sharply higher operating costs on intra-EU routes. Reports from sector analysts indicate that airlines spent several billion euros on allowances in 2024, with totals expected to rise significantly by 2030 as free allocations disappear and the cap tightens further. Aviation groups contend that this trajectory could force higher ticket prices for European passengers and erode margins for carriers already facing high fuel and airport charges.

Some policy studies suggest that while the ETS has contributed to emissions reductions, it has also intensified long-running concerns about carbon leakage and competitive distortions between regions. For airlines, the fear is that a unilateral European approach will simply reshuffle traffic flows rather than cut global emissions, as passengers reroute via hubs where similar carbon costs do not apply.

Environmental organisations counter that a meaningful carbon price is essential to drive investment in cleaner fleets and sustainable fuels. They argue that weakening the ETS would jeopardise the EU’s climate targets and reward operators that delay decarbonisation, although many acknowledge that complementary measures are needed to prevent economic disruption.

ReFuelEU fuel mandates and SAF supply challenges

The EU’s ReFuelEU Aviation regulation, which began to apply in 2025, requires gradually rising shares of sustainable aviation fuel in jet fuel supplied at EU airports. While airlines broadly support SAF as central to long-term decarbonisation, carriers and airport groups highlight that supply remains limited and significantly more expensive than conventional kerosene.

Publicly available information shows that the cost premium for SAF can be several times that of fossil jet fuel, depending on feedstock and technology. European and international airline associations estimate that this price gap translates into billions of dollars in additional fuel costs at current mandate levels, even before higher blend requirements take effect later in the decade.

Airlines and airports have urged Brussels to complement mandates with a more comprehensive industrial policy, including dedicated investment in European SAF production, expanded access to emissions trading revenues for fuel projects, and more flexible implementation rules. Recent joint statements from aviation and shipping groups argue that without stronger support for clean fuel supply chains, Europe risks exporting demand for travel and trade to regions with looser climate policies.

Supporters of the current framework counter that the EU has already earmarked ETS allowances to help bridge the SAF cost gap and that clear long-term demand signals are necessary to unlock private investment. However, there is growing debate over whether existing incentives are sufficient and how quickly new production capacity can realistically scale up.

Competitiveness fears as traffic shifts to non-EU hubs

A central worry for European airlines is that stricter regional rules on carbon pricing and fuel use could encourage passengers and freight forwarders to route journeys through non-EU hubs, particularly for long-haul travel. Industry analyses frequently cite scenarios where itineraries via hubs in the Middle East, Türkiye or other neighbouring states face lower climate-related surcharges than equivalent journeys via Frankfurt, Paris, Amsterdam or other EU gateways.

Studies referenced by airline groups indicate that even moderate differentials in ticket prices can be enough to shift connecting traffic, especially for price-sensitive leisure passengers and cargo customers. Once connections are established through rival hubs, European airports and airlines can find it difficult to win them back, given network economics and alliance structures.

Airport operators and regional business groups warn that such shifts would not only hit airline profits but could also reduce connectivity for secondary European cities. Fewer direct links to long-haul destinations could have knock-on effects for tourism, trade, and investment, particularly in regions that rely on air links to attract visitors and international business.

Climate policy advocates respond that fears of massive traffic diversion may be overstated and that well-designed mechanisms like the global CORSIA offsetting scheme and the EU’s Carbon Border Adjustment Mechanism can help balance competitiveness concerns. Nonetheless, the evidence of rising surcharges on some European itineraries has kept pressure on policymakers to assess how rules are influencing routing decisions.

Industry proposals for recalibrating EU climate policy

In response to these pressures, European airline associations and allied transport groups have put forward a range of proposals for adjusting the current policy mix rather than rolling it back entirely. One prominent suggestion is closer alignment between the EU ETS and CORSIA for international flights, with some stakeholders arguing that duplicative measures should be avoided to limit cost overlap.

Another avenue being promoted is a more targeted use of ETS revenues to support decarbonisation in aviation. Sector roadmaps call for a larger portion of auction proceeds to be directed into SAF production, modernisation of airport infrastructure, and research into new propulsion technologies, instead of being channelled into general public budgets.

Airline and airport groups are also advocating greater flexibility within ReFuelEU, such as expanded book-and-claim systems that would allow SAF produced at one location to be credited to flights elsewhere, smoothing supply constraints. Policy proposals further include expanding transitional support for early adopters of cleaner aircraft and encouraging cross-border coordination on fuel mandates to minimise market fragmentation.

At the same time, several think-tank reports emphasise that any recalibration of EU rules will have to preserve the bloc’s credibility as a climate leader. The debate is increasingly focused on how to sequence measures, deploy financial support, and share costs between the sector, governments, and travellers, rather than on whether aviation should face climate obligations at all.

What travelers can expect in fares and route choices

For passengers, the policy debate is already visible in the form of environmental surcharges and explanations of climate-related costs in fare breakdowns. Some major European airline groups have publicly indicated that climate and fuel policies will add several euros to the price of many intra-EU tickets and can result in much larger differences on intercontinental itineraries over time.

Travelers booking long-haul journeys from Europe may increasingly notice competitive offers via non-EU hubs, reflecting differing regulatory and tax regimes. Industry observers note that while such routings can be cheaper, they often involve longer travel times and additional connections. For frequent flyers conscious of their environmental footprint, the growing availability of SAF contribution options and detailed emissions information is also starting to influence booking decisions.

In the medium term, the outcome of the EU’s ongoing reviews of the ETS and associated climate instruments will help determine how sharply airfares rise and how Europe’s route maps evolve. If more of the carbon and fuel cost burden is offset by targeted support for clean technologies, the impact on ticket prices may be more moderate than airlines currently fear. If not, carriers suggest that the combination of higher operating costs and intense price competition could accelerate consolidation and further reshape the continent’s aviation landscape.

For now, European aviation remains committed on paper to achieving net-zero emissions by 2050, and airlines continue to place large orders for more efficient aircraft. The question confronting policymakers in Brussels is how to adjust carbon rules so that the sector can deliver on decarbonisation goals without losing ground to competitors beyond the bloc’s borders.
