This “positional” paper discusses the changes in Planning driven by Climate Change, introducing the concept of “Strange Planning change” to address the “perception” of uncertainties associated with the global phenomenon of Climate Change and the resulting transformations within the planning field. The paper highlights three forms of innovation in climate change-oriented planning: Contents’ Innovation, driven by context and governance, aligning with European priorities; Procedural Innovation, focused on evaluating and enhancing the sustainability of investments throughout their life cycles; Analytical-Relational Innovation, which emphasizes the importance of communicative and participatory processes in governance, stressing the legitimation of scientific knowledge in the face of uncertainty and addressing issues of climate justice. The analysis draws on the evolution of planning in Italy and other EU countries and emphasizes the need for ongoing reflection on the status, theories, and tools of Planning to better understand the factors driving transformation and to effectively operationalize future strategies.
