Climate compensation or how much forest should you pay for your trip?
Erste Asset Management shows how much surface area of forest is required in order
to offset a trip of 12,000 km.
You cannot make an omelette without breaking eggs; and you cannot travel far without causing emissions – the
carbon footprint of a trip. Travellers who want to compensate for the damage they are causing have been able to
resort to the concept of carbon offsetting for a number of years now.
The recommended compensation can be calculated on numerous websites. Carbon emissions can for example
be calculated and offset on Climate Austria (flights, car rides, and public transportation) or myclimate (flights,
car rides, and cruises). The atmosfair calulator for air travel has received a number of awards. It allows for
hazardous substances other than carbon dioxide in its model. Offsetting donations go to various climate
protection projects.
The planting of trees is a particularly demonstrative form of compensation, and it counteracts the damage caused
in two ways: by producing oxygen and absorbing carbon dioxide. The German foundation “Stiftung Unternehmen
Wald” estimates that one hectare (i.e. 10,000 sq.m.) of forest absorbes some 13 tonnes of carbon dioxide per year.
Younger forests have decidedly less storage capacity.
Note: These data are based on estimates. The data for car, flight, train, and coach were calculated with the carbon dioxide calculator of
the Umweltbundesamt (Federal German Environment Agency), whereas the cruise data are based on the myclimate calculator. Reliable
sources suggest avoiding emissions is preferable to offsetting them.

* These figures refer especially to Germany where trains mostly run on brown coal and only draw 20% of their from renewable sources.
Austrian trains on the other hand are mainly operated by renewable energy (92%). Here, train journeys show a vastly better carbon balance
than bus rides.
