Book excerpt: Performance Metrics for Sustainable Cities provides an overview of measurement systems and tools to enable communities to self-assess and benchmark their progress along a continuum of smart, intelligent, and sustainable development. It begins by explaining the importance of measurement and evaluation for cities and smaller communities, as well as future factors that will need to be considered and embedded into planning processes. Across 14 chapters, the book describes existing evaluation mechanisms that are being used for government funding decisions, awards of recognition, and new measurement systems to assess what makes a city smarter and more sustainable, such as broader sustainable goal targets (UN SDGs), green cities, fabrication cities, and compassionate cities. It presents examples of metrics used for important sustainability and liveability concepts for cities such as how to measure trust, engagement, compassion, circular economy, and so forth. The book ends with reflections on the feasibility of a holistic system of measurement, and the implications of its implementation. This volume will be of great interest to students, researchers and professionals of urban sustainability, planning, smart cities and sustainable communities.
