The CSD Youth Caucus is an international network of over 1000 youth organisations, many of which are themselves national networks, that brings together young people with a desire to build a more sustainable world. The focus of the caucus is two-fold. First, to facilitate youth input into the United Nations Commission on Sustainable Development, the primary international forum concerned with issues of Sustainability, and secondly to foster information sharing and communication between a diverse network of youth organisations who share a common interest in sustainability.
