"Simple in outline; brilliant in conception. This is a rare work that superbly brings together the thinking of key theorists, activists, local people, and practitioners — including a taskforce from Metropolis. We are proud to have been a part of the process."–Alain Le Saux, Secretary General of World Association of Major Metropolises, Barcelona, Spain
"Circles of Sustainability is an extraordinary guide to our way forward. By bringing together the clear insight of political analysts with the citizen-oriented perspective of experienced practitioners, this book changes the paradigm of urban studies. It is a brilliant book that will be used by cities such as Berlin as we seek a better world together." –Michael Müller, Senator for Urban Development and Major of Berlin, Germany
"An inspirational and practical resource for helping our cities drive a revolution in sustainability. The book expertly shows that cities' toughest issues cannot be solved in isolation. No single actor — government, civil society or the private sector — has the all of the answers, nor can we successfully deal with poverty, climate change, unemployment or rights abuses, for example, if we look at them as separate events. Collaboration and holistic approaches must be driving precepts for achieving a better world." –Georg Kell, Executive Director, United Nations Global Compact, New York, USA
"Questions of urban sustainable development will be of critical importance around the world. This book presents a profound re-calibration of the once elusive sustainability concept that integrates social and environmental dimensions; an approach that is theoretically informed and practically operational. A must-read for all who are concerned with the urban future." –Jan Nijman, University of Amsterdam, the Netherlands
"This book, elegantly written, raises one of the most important issues of the 21st century — how to make our cities more liveable. The Chocolatao Project appears, together with many other sustainable practices across the world, as a response to this challenge, by establishing a sound cross-sectoral approach to significantly improve the life of garbage pickers in the city of Porto Alegre." –José Fortunati, Mayor of Porto Alegre, Brazil
"The book is a "must read" for a wide target audience ranging from students, administrators, to planners." – Luc Hens, Environment, Development and Sustainability
