This plan came from a common wish, from our four schools, to work together after a first project very exciting : to go further in our cooperation, to deepen and enlarge our European ambition, we opened our project to other schools, and for a longer period (two-years project). The main objective is still the same : open culturally our pupils, offering them an european point of view on their teaching. Some of our pupils have a strictly local reading of their (urban and natural) environment : broadening to european stakes is a token of intellectual opening, maintained curiosity and future wishes. We are four secondary education schools, with pupils from 11 to 15 (a few of 16). A French school, coordinating, located in Noisy-le-Grand, in Parisian area ; an Italian school, in Grantorto, close toVenice ; a Finland school, in Lahti ; a Greek school, in Larissa ; and, finally, an international school located in Stockholm, Sweden. We are already working together in order to organize transnational activities, between our different classes and disciplines. European Weeks will be organized in each school to present ambassadors pupils, exposing the projects'advances in their school. The results we expect by means of this activities will be important at the level of the local liveliness, for each school. It will raise awareness among several hundreds of pupils per school, about European and environmental themes. Thereby, it is all the families related to, and the localities around, who will hear about practical progresses ensuing these exchanges. Pupils, families, urban network, but also teachers' team, this project will highlight positively, locally and pragmatically what European cooperation means into everyday life. It will higlight as well a necessary awareness from all of us about our ways of life : how to preserve our environment through sustainable cities, respectful or its inhabitants and its immediate natural and living neighbourhood, that is to say biodiversity.In the long-terme, and in collaboration with cultural, teaching and social associations, this project will present some benefices that will go over immediat interests, entering into a more substantial scale:sens of reponsabilities development, opening to others, that will no more be a simple concept but an obviousness, a reflex, environmental and civic sense development, and more particularly a local,national and European civism. At last, development, beyond civism, of interpersonal friendships, cement of a proper European collective project.
