**6. Conclusions**

This study has focused on seeking to explain the factors that influence the perception of a sustainable destination image by tourists. The importance of carrying out this research is justified by the growing concern shown by tourists about the impact of their activity [83]. DMOs must adapt to the new demands of tourists and design strategies that allow them to position themselves as a sustainable destination if they want to remain competitive in this day and age in which sustainability is fundamental [83].

In order to achieve the aims of this study, information was collected from tourists from 18 European countries who have visited the Canary Islands. This is presented as an appropriate destination to study sustainability [70–73].

The findings of this research confirm that the primary and secondary images of the destination, the travel motivations of tourists, and their nationality, as well as their age and level of studies influence

their perception of SDI. This gives emphasis to the importance of segmentation in the design of destination marketing strategies to position the destination as sustainable.
