How is CO₂ calculated?

The CO₂ of a trip is made up of two parts:

• Your journey: the route from your starting point to the stay, for the way you travel (car, train or plane).
• Your stay: the footprint of the accommodation, from the data we hold for each property.

Your Net CO₂ adds up the CO₂ of your paid trips and takes away what your planted trees absorb in a year. A figure above zero means you have emitted more than you have offset so far.
