Red Apples – Green Apples is a dance/visual arts project, which was started by an intercultural group of artists, teachers and researchers with 10–11-year-old children living in Cape Town and Copenhagen in 2017. The project has since focused on the school class in Cape Town with biannual project weeks ending in 2020. The activities of the project have contributed to illuminating how arts education can promote the culture–nature dimension of the UN Sustainable Development Goals, and from a more philosophical viewpoint what children can learn through artistic–educational collaborations about themselves, others and their surroundings. In this article, examples drawn from videographic material and children’s experiences expressed in multimodal formats are discussed in relation to SDG no. 4 focusing on quality education and the implementation of the new EU strategic approach to international cultural relations.
