With a free account you can save your CO₂ calculations and continue planning — from the result to the finished trip.
Calculate the CO₂ footprint of your 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.
