This paper explores the epistemic and moral responsibility individuals and institutions bear for climate change and sustainability. Highlighting challenges individuals face in understanding climate information, it emphasises the pivotal role of governments and intergovernmental institutions in exercising collective intentionality regarding climate change mitigation and sustainability education. Despite the commendable efforts of other collective entities, such as NGOs and climate movements, this responsibility belongs solely to national governments and intergovernmental institutions because they have a unique ability to create social rules. However, (...) such action remains a desideratum. Current data on ecological crises show that there is a pressing need for heightened awareness and decisive, concrete action. (shrink)
