Take the train, not the short-haul flight
For European city hops, the carbon gap between plane and train is enormous — flying can emit several times more per passenger. Swap the next short-haul flight for rail and you cut the trip's footprint while skipping the whole airport ordeal.
Flying is, per hour, about the most carbon-intensive thing a typical person does — and short-haul is where it looks worst of all. Take-off and the climb burn fuel hard, so a brief hop has a punishing footprint for the distance covered. Run the same journey by train and the per-passenger emissions can drop several times over, because electric rail moves a lot of people very efficiently. For European city-to-city trips, this is one of the largest single cuts an ordinary traveller can make, and it needs no new kit or habit — just a different booking.
The reason it feels like a sacrifice is the clock, and that’s where people misjudge it. Flying looks fast on the headline, but door-to-door the gap shrinks fast once you add the journey to the airport, the two hours of queuing and security, and the trek from a distant airport into the actual city. Trains drop you in the centre, with no liquid rules, no baggage fees and a seat you can work or doze in.
The honest caveat: on longer routes the train really is slower, and fares aren’t always cheap if you leave it late. Book early for the saver fares, consider a pass if you’re hopping between cities, and pick the routes where rail genuinely competes — most European short-haul hops do. Reframe the journey as part of the holiday rather than dead time, and swapping one flight a year quietly outweighs a long list of smaller green habits.
How to do it
- Next time you'd reflexively search for a flight, check the rail route first — for many European city pairs, centre-to-centre rail is competitive once you add airport time.
- Compare door-to-door, not gate-to-gate: count the trek to the airport, two hours of check-in and security, and the trip from the far airport into town.
- Book early for the cheapest fares — like flights, rail tickets are usually far cheaper weeks ahead than on the day, especially the saver fares.
- For longer routes, treat the journey as part of the trip: pick a scenic line, pack a book and a snack, and use the time to read, work or just watch the landscape.
- Consider a rail pass (such as Interrail) if you're stringing several cities together — it can beat buying separate tickets and adds flexibility.
Pro tips & pitfalls
- Short-haul is where flying looks worst: take-off and landing burn fuel heavily, so a brief flight has a high footprint per kilometre — exactly the trips rail replaces best.
- On the train there are no liquid limits, no baggage fees and you arrive in the city centre, so factor the cancelled taxis and add-ons into the cost comparison, not just the headline fare.
What it's good for
Good for the planet
- Cuts CO₂ Per passenger, a short-haul flight can emit several times the CO₂ of the same journey by train — one swapped flight is among the single biggest cuts an individual can make in a year.
