The Swiss Youth Hostels model is unique and very successful. Guests can make a voluntary climate contribution, which is used firstly for compensating for the emissions, and secondly for an internal climate fund. This fund finances internal measures for reduction (e.g. nationwide improvements to reduce water consumption, installation of solar panels and photovoltaic systems). Thanks to these and other measures, Swiss Youth Hostels have managed to gradually reduce the emissions per overnight stay by more than half the tons of CO₂ per square meter in recent years. To compensate for the remaining emissions, Swiss Youth Hostels supports myclimate high quality climate protection projects.
