Eco-Oikos: Sustainable Options' is a 10 days Training Course, where 27 youngsters and youth workers, from 9 countries, will have the opportunity to explore the idea of sustainable development. As planned by the EU's growth strategy for the coming decade "Europe 2020", the environmental issue is one of the global challenges which the EU is called upon to address, because the protection of the environment is one of the priorities for smart, sustainable and inclusive growth that promotes a sustainable economy, which limits the negative effects on the environment. This initiative offers an innovative approach to these issues, through the direct involvement of participants: in fact they are the protagonists of the entire design process, creating opportunities to meet and debate, aiming a sustainable development and focused on good practices. Based on the values of Democracy, Participation, Tolerance, Patience, Active citizenship, Ethics and Empowerment, this Training Course emerges now as an innovative training program to enhance youth worker's competences to empower young people to take active participation in the change towards a more sustainable society. The sessions will be non-formal and experiential, with space for feedback and evaluation, with a session for reflection each day. The primary aim of this course is to to enhance youth worker's competences to empower young people to take active participation in the change towards a more sustainable society. We hope to contribute to build a SUSTAINABLE LIVING between citizens and the environment and a future in which ECOLOGY is no longer an emergency but a way of life and where ENVIRONMENTAL EDUCATION no longer a series of concepts to be transmitted but the concrete daily practices.
