Bus, train, flight or rideshare? Every mode of transport has a different CO₂ footprint. At fromAtoB we want you to be well informed every time you book a trip, so we show the CO₂ emissions of every journey on our site, along with price, travel time and stopovers.
You can also use our CO₂ tags and sorting feature to find the lower emission options for your travel needs.
We analyse the CO₂ emissions for each type of transport offered on our site.
Our advanced algorithm calculates CO₂ emissions based on several factors, such as the mode of transport, route length and number of stopovers.
We label the individual results with the amount of CO₂ emitted in kilograms, so you can sort to make more informed decisions.
