We enable you to voluntarily offset the CO2 emissions of your train journey. No matter whether you want to make your personal contribution before or after your journey, you decide. You can also gift the offsetting of train journeys to other people. By buying a CO2 certificate, you immediately make your voluntary contribution to your train journey.
Here, too, we deliberately refrain from using a CO2 calculator and base our calculations on the average CO2 emissions caused by a national or international train journey.
