Climate change – and especially the increase in extreme events – represents an opportunity and, at the same time, a new challenge for urban and regional planning processes, also leading to the need to define adequate policies. Currently, the state of art about climate protection planning is far to be homogeneous, as mitigation and adaptation policies clearly shows differences by city, as well as by cultural-territorial characteristics.
Cities of different sizes and contexts have begun integrating climate change into urban policies and local agendas (among others, New York, Chicago, Toronto , Stuttgart, Vienna, London, Padua, Bologna …). These policies and agendas introduce new management tools (climate plans, climate adaptation plans, plans for sustainable energy etc.). In most of the cases, however, innovative plans and policies addressing climate preparedness are still conceived as “experimental” and are not mainstreamed into ordinary spatial planning regulations.
