Is the train always greener than flying?
Within Europe usually yes, because trains emit far less CO₂ per passenger kilometre. For very long distances there is often no practical rail option – then travelling less often but for longer helps.

Save results & plan your trip
With a free account you can save your CO₂ calculations and continue planning — from the result to the finished trip.
How much CO₂ does my trip produce?
It depends mainly on the mode of transport and the distance: flights produce considerably more emissions per person than train or coach journeys over the same route. The CO₂ calculator works out the emissions for plane, train, car and accommodation and shows greener alternatives.

How do I calculate the carbon footprint of my trip?
Travelling causes CO₂ emissions – but how much exactly? Our CO₂ calculator transparently shows you the ecological footprint of your next trip. Whether by plane, train, car or ship: compare different modes of transport and accommodation types to make more conscious decisions.
The difference is especially large for transport: a flight produces about 18 times more CO₂ per kilometre than a train journey. The choice of accommodation also makes a difference – camping produces only a fraction of a hotel’s emissions. With our tool you can explore different scenarios and find the most climate-friendly option for your trip.
If you cannot avoid the emissions of your trip, atmosfair offers the option to offset them. Donations fund climate protection projects in developing countries and help to reduce global CO₂ emissions. Sustainable travel starts with knowledge – and that’s exactly what this calculator is for.
Which other tools help with trip planning?
Use the CO₂ calculator as a building block for conscious trip planning. Calculate costs with the Budget Calculator, organise everything in the Trip Planner or find a destination with the Vacation Finder that is easy to reach and suits your wishes. Then create a Packing List and start the excitement with a Countdown.
