All young people aged 10 to 30, whether they are students in compulsory school or active in non-formal education (scouts, youth organizations, etc.) are invited to participate in the global “1 million youth actions challenge” initiated by the SDC. The initiative encourages young people to implement concrete actions for a more sustainable future in line with one of the four themes of the United Nations Sustainable Development Goals (SDGs): water, biodiversity, climate change and sustainable consumption.
