The KSJ Rottenburg-Stuttgart, the student association in the BDKJ, qualifies students who want to work for fair trade and global justice at their school. As part of the training, the students learn, test and reflect on both the sale of sustainably produced products and the implementation of smaller campaigns and projects. Cross-school work also promotes networking and exchange between those active in different schools and enables synergies and cooperation. In addition, a workshop on engagement opportunities and an action calendar are being developed.
