The Youth Exchange E.A.R.TH. took place in June 2010 in Verteneglio-Brtonigla, Istria, in Croatia. During 6 days of activities 18 young people coming from France and Croatia gathered togather to allow them to discuss and confront on environment and sustainable development issues. It aims at strenghtening youth participation regarding environment whilst fostering mutual understanding, tolerance and solidarity between them by sharing their experiences on the situation they are facing in their home countries as "environmental citizens", taking the fact they are young people coming from France, an EU country that has EU standards integrated in their environmental policy since a long ago, and Croatia i.e. a pre-adhesion country that is still integrating them in its policy. In the exchange, through non formal learning methods, 16 participants and 2 group leaders improved their knowledge about their respective countries and cultures by learning about practical examples of environmental protection and European tools for sustainable development. The importance of being young European citizens who are inheriting the environment was discussed for the benefit of the local-home environmental situation of both groups. They also created a sculpture with locally collected waste to rise awareness on environmental issues among citizens of the hosting community thus fostering intercultural dialogue among themselves and between participants and the hosting local community . The activities carried out during the youth exchange have been proposed in a short documentary on the youth exchange E.A.R.TH. with the aim to build opportunities for future partnerships and to enable multiplying effect of this exchange after the end of the project.
