Embedding climate resilient development principles in planning, urban design, and architecture means ensuring that transformation of the built environment helps achieve carbon neutrality, effective adaptation, and well-being for people and nature. Planners, urban designers, and architects are called to bridge the domains of research and practice and evolve their agency and capacity, developing methods and tools consistent across spatial scales to ensure the convergence of outcomes towards targets. Shaping change necessitates an innovative action-driven framework with multi-scale analysis of urban climate factors and co-mapping, co-design, and co-evaluation with city stakeholders and communities. This Element provides analysis on how urban climate factors, system efficiency, form and layout, building envelope and surface materials, and green/blue infrastructure affect key metrics and indicators related to complementary aspects like greenhouse gas emissions, impacts of extreme weather events, spatial and environmental justice, and human comfort.
