Tourism is one of the largest and fastest growing sectors of the global economy. According to the World Travel & Tourism Council it was worth 8 trillion Euros in 2018, outperforming the global economy for the eighth consecutive year. On the one hand tourism creates a surplus for the European Union economy, it comprises over 2 million businesses employing over 13 million people, but on the other hand it has to deal with new challenges linked with overtourism and with the climate emergency. Indeed the exponential growth of the tourism sector has generated issues like overtourism and gentrification. At the same time there is a general growing concern that tourism needs to be more environmentally sustainable through the reduction of energy consumption and fossil fuels. Demands for more sustainable tourism have also led to the development of alternative forms of tourism. ECO.TOUR fits into this context since it comes from one of the identified needs of the European Development Plan (EDP) initiated with the KA1 VET project ETHOS in 2017 and continued with ETHOS II in 2019. The plan outlined a real internationalisation strategy carried out with the collaboration of VET schools to increase the quality of VET courses related to Tourism, which nowadays has to go hand in hand with environmental sustainability.Starting from this context, the main objective is to foster the use of innovative teaching methodologies on sustainable tourism in VET schools. The specific objectives will be: updating teachers’ competences in teaching technical subjects in training courses pertaining the tourism sector; integrating in VET curricula training activities aimed at strengthening the education on environmental sustainability; enhancing the internationalisation strategies for the development of competences on sustainable tourism in teachers and learners.In order to reach these objectives, three thematic seminars (joint staff trainings) will be organized in the framework of ECO.TOUR. In particular, the activities will focus on: innovative teaching approaches applied in training courses related to the tourism sector; methodologies to teach environmental sustainability at school; internationalisation of education. ECO.TOUR will address several target groups. The target groups which will be involved directly are: VET teachers, Headmasters, mobility experts’ staff, VET students, while business actors, civil servants and policy makers and families will be involved indirectly.The main impact of the project will be fostering the debate on how to improve the quality of training and skills of educators, and it will also launch concrete actions that will provide tangible solutions for introducing topics like environmental sustainability at school. It will have a substantial impact at local level since it will increase awareness on new teaching methodologies to introduce sustainable tourism in training courses related to this sector, collecting good practices and encouraging the investment in on-the-job training of teachers.
