The COVID-19 pandemic left a strong mark on the tourism sector and represents a turning point in its evolution. After the activities were gradually resumed, changes in behaviour were observed both in the companies in the field and in terms of tourists. The knowledge of these changes is of strategic importance for the future because they will determine the managerial decisions at the microeconomic level and the trends of evolution at the macroeconomic one. Our research focused on identifying the change in tourist behaviour perceived by tourism companies and how these changes are integrated into business decisions. The research was carried out within the CredinGreen international project – `Responding to tourism market changes caused by COVID-19 and the EU Green Deal through micro-credential-certified upskilling of SME tourism managers`.
