"In Germany, Belgium, the Netherlands and France, students and teachers are seriously concerned about the future of our planet and the sustainability of the earth. This project is offering them the opportunity to enter into a Europe-wide exchange on sustainability strategies in European schools, to discover common values and to understand the diversity of Europe as an opportunity for themselves.We have chosen disadvantaged students to develop solutions for sustainability in their schools and to encourage them to find career and work opportunities in their country or in other European countries. While asking ""what do you and your school do for the environment?"" the participating students become environmental detectives who design solutions for a sustainable school at their schools. The students should then exchange ideas with their European classmates about the possibilities of a sustainable school in Europe and say why they like different ideas (""I like your ideas""). They give their European classmates recommendations and get information about the diversity of European values and cultures. In the spirit of European added value, everyone involved can learn from each other. The ideas that are best implemented in their respective schools should then be tested. At the end of the project, the students design scenarios for a sustainable school in 2050.Students get to know each other during the project work and test together the approaches developed during the project. They will also discuss different ways of transportation based on sustainable criteria and choose their way of transportation to get to their partner school in the Netherlands, Germany, France or Belgium. Therefore the German students plan to visit their Belgian classmates by bike. The responsibility assigned to the students will consolidate them in their personality and prepare them for future challenges.Students will get in contact which each other via the eTwinning project platform. This way of communication will deepen their basic information technology skills and foreign language skills. Activities such as a logo competition, presentations by the students on their school, their region and country, such as video conferences of all participating institutions on the current progress of the project, regular competitions (e.g. the best idea of the month) and at the same time in all schools action days (for example, A day without electricity) are additional connecting structures and support the exchange of French, Belgian, Dutch and German students with each other. The extracurricular partner of the coordinating school at the University of Bonn, will accompany the schools regularly review targets and monitor the distribution channels of the project work as well as its results in the form of the guidelines and the documentary.The aim is to design a ""path to school sustainability in Europe"" with the best practiced ways to be implemented in schools in Europe. In addition to a print version, the guideline will be published on the homepage of the coordinating school to make it accessible to a general public. The proposals drawn up also flow into the school's internal curriculum. A documentary with film sequences of the project work and the mobilities on site also offers all those interested an insight into the project work and shows interested colleagues how to implement the project in their schools."
