Basil Bornemann from the University of Basel’s Sustainability Research Group explained in the prep session that the debate about climate justice historically emerged from different sources, such as the concept of environmental justice. Used by both scholars and social actors, climate justice serves as an umbrella term for diverse perspectives and practices. While somewhat ambiguous, the concept spans discussions on the causes and drivers of climate change, its impacts and effects, governance and policy, communities and actors, principles and rules as well as strategies and practices. Climate justice is applied in philosophical reasoning, empirically backed arguments as well as concrete actions on the streets.
