While human behavior has often been identified as a cause of environmental stresses, it is much less frequently identified as a source of solutions. The Garrison Institute’s Climate Mind and Behavior (CMB) Program connects new insights from social and behavioral sciences about the drivers of human behavior with new thinking on solutions to climate change and other environmental issues. In 2011 the Garrison Institute held three high-level symposia for each of the three projects that make up CMB, including “Climate, Mind and Behavior,” exploring and applying social, behavioral, and cognitive science principles to environmental policies and programs; “Climate, Cities and Behavior,” developing effective, low-cost, people-centered strategies for achieving more sustainable resource use practices; and “Climate, Buildings and Behavior,” developing and implementing climate friendly in multifamily residential and commercial buildings. This report is a summary of key content from these three meetings.
