The climate crisis is scientifically proven and we are affected with its impact. Therefore we urgently need to adress environmental issues and pursue the goals of sustainability, particularly with regard to the Paris Agreement: All participants in our society need to make a great effort to face the biggest challenge in the history of mankind. As a result, together with our partnerschools and extracurricular partners in Europe we will contribute to environmental protection and effect our environment as multipliers. Offering a holistic approach, we increase the competence of all participants in different fields that are relevant for sustaniability. We are setting the focus on professional information (facts about climate change), product creation, strategies of non-violent communication (according to Marshall Rosenberg) and school development.
