Climate change and sustainability are buzzwords that are currently in high demand. In tourism, the favorite hobby of Germans, the ambivalence of these terms is particularly evident. This book explains how tourism can and should be ecological and sustainable. By presenting the organizational structure, tools, and procedures of sustainable tourism, the construct is examined in its components. Starting with the fundamentals of sustainability, this book leads into the network of influencing bodies at both the European and national levels. Selected examples investigate the practical effects of success and demonstrate implementation options for one's own sustainability. The book aims to serve as a foundation for interested readers, to inform tourists about the interactions of sustainable tourism, and to provide tourism businesses with points of contact and further guidance for specialization.
