Climate change has been the defining global issue of the past decades. Owing to its wide-ranging and often catastrophic consequences, it is arguably the cause of the 21st century, around which every other issue revolves. Climate change is not only a challenge as to sustainable development, but it is also a human rights issue, because its effects compromise the dignity of those driven out of their homes by rising sea levels or desertification. In short, it is what German education philosopher would classify as a key issue of our era. In this chapter, we argue that, as such, it must be included in what constitutes quality education, and that we need educational approaches that prepare future generations to address climate change as an issue of human rights and environmental injustice. This conceptual analysis is based on an understanding of Global Citizenship Education (GCED) as a foundation for necessary changes, and it advocates for particular steps in teacher education to support these changes.
