The aim of the project is to significantly increase the share of more sustainable travel options in all booked travel products. Thus it is necessary that such travel products are visible (labelling) and bookable (within the information and booking systems). Targeted consultation by the travel agency staff regarding the realization of sustainable holidays can increase the sense of responsibility, efficiency and potentially sufficiency. Accordingly two aspects can be achieved: The advantages and chances of sustainability become visible to travelers and travelers have the possibility to specifically book sustainable products. Thus the sense of responsibility, efficiency and potentially sufficiency can be combined: The traveler consciously and frequently decides to travel sustainable. Hence travel products will be promoted, which use less resources, are bound to a favorable economic and social contexts and thus better correspond to the sustainability criteria.
