ARC3 Series

The aim of the ARC3 series is to ensure ever-deeper coverage of knowledge related to climate change and cities while simultaneously facilitating increased response capacity within cities themselves.

The UCCRN’s first major publication was Climate Change and Cities: First Assessment Report of the Urban Climate Change Research Network (ISBN-10: 1107004209) published by Cambridge University Press in 2011, which we characterize as the First ARC3.  The ARC3 report represents a four-year effort by 100 scholars from 50 cities around the world, and is the first-ever global, interdisciplinary, cross-regional, science-based assessment to address climate risks, adaptation, mitigation, and policy mechanisms relevant to cities.  The assessment articulates urban climate risk frameworks, climate science for cities, and derives policy implications for key urban sectors—water and sanitation, energy, transportation, public health—and systemic issues through land use and governance.


From the Forewords to the ARC3 book:

The ARC3 project will help ensure that we not only create a greener, greater New York for future generations, but that we continue to learn from the lessons of our counterparts across the world, and that we share our progress and our story with our partners throughout government, academia, and the private sector.’
Michael R. BloombergMayor, New York City

‘ … innovative and important. … I am convinced that this body of knowledge will be of direct benefit and inspiration to the cities which we are supporting to develop climate action plans.’
Anna Tibaijuka, Former Under-Secretary General of the United Nations and Former Executive Director, UN-HABITAT

 ‘I am highly appreciative of the work of the members of the UCCRN from developing and developed cities who are participating in the ARC3 activity. Policymakers, administrators, and researchers from cities around the world will benefit from the information provided in ARC3, helping them make more informed decisions about how climate change will affect public health, local infrastructure, and in turn, our economic vitality in the coming decades.’
Rajendra Kumar Pachauri, Chair, Intergovernmental Panel on Climate Change and Director General, The Energy and Resources Institute, New Delhi, India

‘[This] new volume … is a lifeline to sustainability. … The authors of this remarkable report … are at the cutting edge of global science and policy. … The work is a triumph, a must-read study for city planners, mayors, and managers around the world.  The lead editors … merit our special thanks and admiration for taking on a challenge of such global significance, and for bringing the best of the world’s scientific knowledge together in such a useful and comprehensive manner.’
Jeffrey D. Sachs, Director of the Earth Institute at Columbia University and Special Advisor to UN Secretary General Ban Ki-Moon on the Millennium Development Goals

This book has also been endorsed by city leaders of Toronto, Mexico City, São Paulo and Lagos, and by ICLEI – Local Governments for Sustainability.
