Young participants have been introduced to the current environmental challenges and the envisaged policy responses at a European level, and to the techniques of environmental journalism and reporting, by experts in the field, academics, journalists, photo-reporters, as well as by representatives of environmental movements and local authorities. Through an active learning process, based on an interdisciplinary approach and a peer-to-peer learning process, participants have been accompanied to start acting as ‘Green Reporters’, by designing and creating by themselves communication material on environment, presenting their productions to the group, confronting them to fellow participants’ productions, revising and changing them for the better. The project’s productions form a teaching trunk composed by educational material to be used by teachers and environmental educators, while helping to raise awareness on environmental issues among the youth and the general public. As the testimonies by the Greek young participants reveal, the project has helped to enhance participants’ interdisciplinary perspective and enrich their perception on the cross-border dimensions of environmental questions, while the content produced highlights the transnational nature of environmental issues and the European dimension of the responses to these issues.
