EU Weighs Carbon Price on Long Haul Flights From Europe

The European Commission is assessing how to bring long haul international flights into the scope of European carbon pricing, raising the prospect of higher ticket prices on routes connecting the European Union with the rest of the world and intensifying debate over who should pay for aviation’s climate impact.

From Regional Scheme to Global Reach

For more than a decade, aviation emissions within Europe have been covered by the EU Emissions Trading System, which puts a carbon price on flights operating inside the European Economic Area and on departures to the United Kingdom and Switzerland. Publicly available information shows that this limited scope was maintained through temporary derogations that excluded most intercontinental services in order to support negotiations on a global approach to aviation climate policy.

According to technical material published by the European Commission and the European Aviation Safety Agency, these derogations are set to remain in place until the end of 2026, meaning that the bulk of emissions from long haul flights to destinations such as North America, Asia and Africa are still not priced under the EU carbon market. At the same time, airlines operating those routes are gradually entering the United Nations-backed Carbon Offsetting and Reduction Scheme for International Aviation, known as CORSIA, which relies on purchasing offsets rather than on a cap and trade system.

Under the reform of the EU carbon market adopted in recent years, legislators asked the Commission to examine whether the regional scheme for aviation should be expanded to cover a wider range of international services. Parliamentary briefing documents indicate that by 2026 the Commission is expected to review available data and, if appropriate, bring forward a legislative proposal on how to address emissions from extra European flights in a more comprehensive way.

New Options on the Table for Long Haul Routes

Policy papers, expert studies and stakeholder submissions describe a series of options now being explored in Brussels. One scenario would extend the existing emissions trading system to cover a share of emissions from flights departing the EU to non European destinations, for example by applying the carbon price to the portion of a journey that takes place in European airspace or to half of each extra European leg, mirroring rules already in place for maritime transport.

Another option under discussion in analytical work would be to apply EU carbon pricing to all emissions from outbound intercontinental flights leaving European airports, bringing them closer to the treatment of intra European services. Advocates of this approach argue that it would better reflect the polluter pays principle and reduce the competitive distortion between short haul and long haul traffic that currently leaves many of the most carbon intensive journeys outside the scope of the market.

A third pathway considered in some studies would combine a gradual extension of the EU carbon market with continued participation in CORSIA, effectively subjecting European based airlines to both systems for certain routes. According to briefings prepared for the European Parliament, this hybrid model is seen as a way to align regional ambition with the emerging global framework, although it would increase administrative complexity for carriers that already manage overlapping reporting and compliance regimes.

Cost Implications for Airlines and Travelers

Any move to apply a carbon price to long haul flights departing from Europe would have direct cost implications for airlines and, ultimately, for passengers. Analysis by climate policy groups on potential extension scenarios suggests that ticket prices on popular intercontinental routes could rise as carriers pass through at least part of the cost of buying additional emissions allowances. The precise impact would depend on the carbon price, the share of emissions covered, and the extent to which airlines can cut fuel burn through more efficient aircraft and operations.

Industry associations have warned in public position papers that extending carbon pricing to long haul services risks shifting traffic through non European hubs if rival regions do not introduce comparable measures. They argue that connecting passengers might choose itineraries via airports outside the European Union to avoid higher fares on direct services, affecting the competitiveness of European hubs. Environmental organisations counter in their own analyses that demand reduction on the most carbon intensive routes is a desired outcome, and that revenues from carbon pricing could be recycled into sustainable aviation fuel deployment and other decarbonisation measures.

For leisure travelers, the debate is likely to be most visible through changes in ticket prices and route offerings, particularly on long haul holidays and family visits outside Europe. For corporate travel buyers and global airlines, the focus is as much on the predictability of policy as on the level of the carbon price itself, since fleet planning and network decisions on intercontinental routes are typically made several years in advance.

Aligning European Policy With Global Climate Goals

The discussion about pricing carbon on long haul aviation is closely linked to wider efforts to align European climate policy with global goals. International aviation is not directly covered by the Paris Agreement’s nationally determined contributions, but member states of the International Civil Aviation Organization have endorsed an aspirational objective of net zero carbon emissions from the sector by 2050. According to analytical material from European institutions, meeting that objective will require a combination of cleaner aircraft, operational improvements, large scale deployment of sustainable aviation fuels and effective market based measures that influence investment decisions.

Within Europe, the broader climate policy architecture is being reshaped through the European Green Deal, revisions of energy and transport legislation, and the creation of a second carbon market for buildings and road transport. Observers of the process note that this wider shift towards pricing carbon across the economy has increased pressure to address remaining gaps, including emissions from intercontinental flights that begin in the European Union but are largely unregulated from a carbon cost perspective.

Environmental campaign groups and several research institutes have argued in recent reports that leaving long haul flights outside robust carbon pricing risks undermining climate objectives, since a significant share of aviation emissions comes from a relatively small number of lengthy journeys. They contend that extending carbon costs to these routes would send a powerful signal to airlines and aircraft manufacturers about the value of investing in low carbon technologies, while also encouraging passengers and companies to reconsider the frequency and routing of very long trips.

Next Steps and What Travelers Should Watch

According to legislative planning documents, the European Commission is expected to use 2025 and 2026 to gather detailed data on aviation emissions, non carbon climate effects and the interaction between the EU carbon market and CORSIA. This technical work will feed into a formal review of aviation in the emissions trading system and could lead to concrete proposals on long haul carbon pricing before the end of the current policy cycle.

Member states and the European Parliament would then need to negotiate any changes, a process that typically takes several years and involves intense debate about competitiveness, fairness and the distribution of revenues. Travel and tourism sectors across Europe are already following the process closely, weighing the potential for higher airfares against long term benefits such as cleaner fleets and more resilient climate policy.

For travelers planning intercontinental trips from European airports, the emerging policy landscape means that the climate cost of flying is likely to become more visible in the years ahead. Whether through dedicated carbon line items on tickets, higher base fares, or new voluntary contribution schemes linked to more stringent regulation, the price signals around long haul air travel are poised to change as Europe explores how to bring these journeys fully into its carbon pricing framework.
