The GreeNet network aspires to address the increasing necessity to develop an integrative approach in environmental sciences. More specifically, it will collect ground-breaking initiatives in the area of environmental education and green careers counselling, and disseminate relevant good practices. To this end, a European web of teachers will be set up and specially trained through specific educational actions, contests, and summer schools, to develop their competencies to select, adapt and use cutting-edge approaches in environmental school education. The network will take up the results and use them in a way that generates new ideas and innovative solutions, achieving extended awareness-raising on environmental issues. Ultimately, the objective is to help students to become more active and responsible, both locally and globally. This way, the proposed approach shall result in a strong environmental awareness in school communities, leading students to comprehend the significance of protecting the natural environment, as well as the importance of a balanced ecosystem for the orderly operation of human life, thus achieving a major goal of the classroom. Moreover, the focus shall be on the examination of different implications instigated by environment-related aspects, leading to a rather spherical knowledge on the subject. To this line, the project aligns with the recommendations of the High Level Group on Science Education (Rocard, 2007) for increased young peoples’ interest in science. This process shall lead to a new approach in motivating, incubating, and accelerating active participation in initiatives for the protection of the environment, directly linked to various school science subjects and to the future choice of career paths.
