Across Europe, countries are increasingly turning to bans on certain short-haul flights as part of their strategies to tackle climate change and reduce carbon emissions. These measures aim to replace flights on routes where efficient rail alternatives exist, minimising unnecessary environmental impacts while promoting greener travel options.

France’s ban on short-haul domestic flights, effective since May 2023, aims to reduce carbon emissions by eliminating air travel on routes where train journeys of less than two and a half hours are available. 

However, the ban’s impact has been limited. It affects only a few routes, such as those between Paris and cities like Nantes, Lyon, and Bordeaux, resulting in the discontinuation of approximately 5,000 flights annually out of nearly 200,000 domestic flights. 

Critics argue that the measure is largely symbolic, with minimal effects on overall CO₂ reduction. Additionally, the ban does not apply to connecting flights, further limiting its effectiveness. While the policy represents a step toward sustainable travel, its narrow scope and exemptions have led to debates about its actual environmental benefits.

Following France’s lead, Spain proposed similar legislation in 2024, aiming to ban domestic flights where train journeys under two and a half hours are possible. This move affects routes between major cities like Madrid, Barcelona, and Valencia, which are already well-connected by high-speed rail. Spain’s proposal aligns with the European Union’s broader strategy to decarbonise transport, a sector responsible for nearly a quarter of Europe’s greenhouse gas emissions.

The proposal, while similar in its scope and criteria to that of France, is projected to have a more substantial environmental impact, potentially reducing up to two million tonnes of greenhouse gas emissions annually. However, the specific number of flights affected has not been detailed. Given Spain’s larger high-speed rail network—one of the most extensive globally—the potential to replace short-haul flights with train alternatives could surpass France’s policy in effectiveness.

Short-haul flights are known for their disproportionately high carbon emissions per passenger per kilometre compared to other modes of transportation. Airplanes emit about 77 times more CO₂ per kilometre than trains, according to European transport data. By focusing on routes where high-speed rail can replace flights, these bans aim to address unnecessary emissions while promoting rail travel as a greener, more sustainable alternative.

Despite their environmental benefits, bans on short-haul flights face several challenges:

1. Infrastructure Gaps: Not all European countries have the high-speed rail networks needed to make such policies feasible. In countries with underdeveloped rail systems, the transition away from short-haul flights is less practical.

2. Public Resistance: Travelers and industry stakeholders argue that such bans restrict consumer choice and may negatively impact regional economies reliant on air travel.

3. Aviation Industry Pushback: Airlines have criticised these policies, claiming they oversimplify the emissions problem and do not address the need for cleaner aviation technologies.

Europe’s extensive high-speed rail network plays a critical role in making these policies feasible. Countries like France, Spain, and Germany have invested heavily in rail infrastructure, offering a reliable, fast, and comfortable alternative to air travel. Beyond environmental benefits, rail travel provides additional perks, such as city-center-to-city-center connectivity and fewer security delays, making it a preferred choice for many travelers.

The movement to ban short-haul flights is not just about reducing emissions—it’s a symbol of the transformative changes needed to meet global climate goals. Aviation currently accounts for approximately 2.5% of global CO₂ emissions but is growing rapidly, making it a key target for decarbonisation efforts. These bans highlight how governments can take decisive action to address emissions while encouraging the use of existing, greener infrastructure.

The push to ban short-haul flights in Europe, led by France and followed by Spain, marks a significant step toward sustainable travel and climate responsibility. While challenges remain, these policies demonstrate the potential for reimagining transportation systems to align with environmental goals.

As more countries adopt similar measures, the global travel landscape could shift significantly, offering a blueprint for reducing aviation’s impact while promoting cleaner alternatives like high-speed rail. By prioritising policies that cut unnecessary flights and invest in rail networks, Europe is setting a standard for sustainable transport that other regions may soon follow. For travelers, this signals a future where greener travel isn’t just an option—it’s the norm.
