 The GreenTourism.eu tool is a repository of best practices and case studies related to sustainable tourism and at the same time it is an educational tool that allows for students to test their knowledge about sustainable tourism. The tool can be used by tourism businesses to train their staff on the matters of sustainable development and to train them about concrete best practices that can be implemented in their enterprises functioning, helping them use less resources, be more efficient, and more environmentally sound at the same time. I find it extremely useful for not only for students who are speciality of tourism but also it could be used for enlarging knowledge in English for in this topic and moreover it could be used as a motivator for the students to enlarge their knowledge in English and to be more ecologically orientated and to think about ecology.
