This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation. Rather than merely advancing the societal shifts necessiated by climate change, legal structures are being reshaped by the urgency of climate goals, the expansion of governance fields, and the deepening societal, spatial, and temporal dimensions of climate policy.The article traces the evolution of climate law, highlights the conceptual opening towardmultidimensional challenges, and analyzes how the transformation imperative alters traditional legal doctrines and decision-making paradigms. It introduces three guiding dimensions – space, time, and society – as analytical lenses for understanding how law can both guide and be shaped by the transformation. The authors propose a research agenda for transformative climate law that goes beyond doctrinal reconstruction, calling for interdisciplinary engagement to explore the law’s dual role as both agent and subject of societal change.
