The EU’s Plan to Extend Carbon Pricing to Long-Haul Flights: Options, Costs, and the Industry Backlash

This decision doesn't happen in a vacuum. The July proposal is part of a broader overhaul to align the entire ETS with the EU's legally binding 2040 climate target of a 90% net emissions reduction (compared to 1990 levels) . The carbon market's overall cap is already on a steep decline, and the aviation sector has seen its free allowances completely phased out, leaving carriers fully exposed to carbon costs on covered routes from 2026 .

The Cost Calculus: Record Emissions, High Carbon Prices

The stakes of the decision are magnified by current market conditions.

• Record Emissions: European aviation emissions reached an all-time high of 195 million tonnes of CO₂ in 2025. Crucially, 68% of those emissions from departing flights are not priced under the current intra-EEA limitations .
• High Carbon Prices: EU Allowance (EUA) prices have fluctuated between €70 and €100 per tonne throughout 2025-2026. This makes the financial impact of any scope expansion substantial. A detailed analysis by CE Delft for Transport & Environment estimates that by 2030, a ticket from Amsterdam to Hong Kong could see an extra cost of €40, while a flight to Istanbul could rise by €19 .

The Industry Revolt: "Further Penalise European Passengers"

The Commission's intentions have been met with a coordinated and forceful counter-offensive from the airline industry, centred on arguments about competitiveness, trade, and the integrity of the global CORSIA framework.

Airline CEOs' Joint Letter

On June 8, 2026, the CEOs of Europe's largest airlines—including Air France-KLM, IAG (British Airways' owner), Lufthansa, and Ryanair—sent a joint letter to Commission President Ursula von der Leyen. Their message, seen by Reuters, was blunt: "Expanding EU carbon pricing to extra-EEA flights will further penalise European passengers and businesses by increasing the cost of air travel" .

The CEOs laid out three core warnings :

1. Higher Ticket Prices: A direct and unavoidable impact on consumer costs for long-haul routes.
2. Competitive Disadvantage: Non-European carriers on the same routes would not face the same carbon costs, giving them a decisive commercial edge.
3. Trade Retaliation: The move risks triggering a repeat of the 2012 international dispute when non-EU countries, including China, the U.S., and Gulf states, fiercely opposed the ETS's initial attempt to cover aviation, with some threatening trade reprisals.

The letter also argues that a unilateral ETS expansion directly undermines the global CORSIA scheme, which is due to enter its mandatory phase in 2027. The industry fears market fragmentation, with carriers having to comply with two overlapping and conflicting systems .

IATA's Push for a Global Solution

The International Air Transport Association (IATA) has been the most vocal institutional opponent. In a March 2026 statement, it urged the EU to "ensure full implementation of CORSIA for all international flights, including flights within the EEA" to prevent "damaging regulatory fragmentation" . IATA has accused the EU of trying to "hijack CORSIA" and has warned that the ETS expansion would "destabilize the international consensus" for aviation carbon reductions . Its lobbying since 2025 has focused on replacing ETS coverage of intra-EEA flights with CORSIA, a move that analysts say would significantly weaken emission cuts .

A Wider Aviation Alliance

A broader alliance of European aviation bodies, including Airlines for Europe (A4E) and the Airports Council International (ACI) Europe, published an open letter on June 5, 2026, warning that the ETS expansion could trigger an "aggressive trade war and cripple continental airlines" . The alliance pointed out that the current CORSIA derogation expires at the end of 2026, and its automatic extension without the new proposal would already broaden the ETS's scope .

Cracks in the Member State Consensus

The political dynamics within the EU Council are complex. While no definitive public list exists, a coalition of nine member states has reportedly pushed back against the expansion in preparatory negotiations. Historical records from the Fit for 55 package discussions show that Ireland has raised subsidiarity concerns, and the Czech Senate formally requested an evaluation of the risk of cost increases . Concerns about connectivity for peripheral and outermost regions are also prominent.

Conversely, a bloc of climate-ambitious states, reportedly led by France and the Netherlands, is pushing in the opposite direction, supporting the extension of the ETS to all departing flights .

What Happens Next

The timeline is tight and the legislative path is clear:

• July 2026: The European Commission publishes its impact assessment and legislative proposal as part of a wider climate package .
• 31 December 2026: The current legal derogation shielding extra-EEA flights from the ETS expires .
• 1 January 2027: The mandatory phase of CORSIA begins globally, alongside the start of full auctioning for aviation allowances within the existing ETS .

The Commission's proposal is only the beginning. Once tabled, it will be subject to intense negotiation and potential amendment by both the Council (representing member states) and the European Parliament throughout late 2026 and into 2027. The outcome will determine whether the carbon cost of flying from Europe remains a regional affair or becomes a global one.
