This project seeks to assess the sensitivity of tourism managers in the municipalities of the Minho Urban Quadrilateral (Barcelos, Braga, Guimarães and V. N. Famalicão) to good sustainability practices. The aim of our research is to gather together a set of good practices that tourism sector activities located in these municipalities are adopting or could adopt, demonstrating that it is possible to make the business more sustainable, with greater economic, social and environmental benefits.
