The mission of the Urban Climate Action CRC is to analyze and contribute to different forms of collective action in the face of climate change in urban areas, through comparative research and partnerships with organizations and communities. Through four research axes and multiple projects and collaborations, the Chair links three elements at the heart of urban climate action: the different forms of collective and citizen action, the anchoring of climate action in territories and living environments, and the recomposition of urban infrastructures. The four research axes are urban infrastructure in transition; climate justice and caring practices in communities; transformation of suburban living environments; and the emotions of climate action anchored in changing territories.
