Post-growth encompasses various approaches that break with the idea that current production systems and consumption patterns can grow globally in the long term. The term represents a movement that strives toward human well-being and prosperity beyond economic growth as a goal. Related concepts and initiatives for post-growth societies describe steps for a socio-ecological transformation, not an ideal final state. This approach offers potential in the context of Education for Sustainable Development and transformative literacy; however, the provision of supporting research findings remains a necessity. Our research project addresses these debates by reflecting on young people’s ideas about post-growth to derive implications for geography education. To this end, 25 participating 15- to 17-year-olds divided into seven focus groups took part in three meetings. The empirical data from the focus group meetings were evaluated and processed systematically. This chapter presents and discusses selected results.
