Environmental sustainability is a necessity for all countries worldwide, and it is strongly related to human quality of life. Given that sustainability problems largely result from human-environment interactions, social and behavioral research is developing as a necessary complement to natural-science and technological studies of environmental problems. To demonstrate this, the various authors address key theoretical, methodological and policy-making questions about the behavioral dimensions of environmental sustainability. Successively considered are the appreciation of environmental risk, citizens8217; annoyance from environmental noise, the evaluation of urban environmental quality, the restorative significance of nature experiences, fundamental behavioral processes and environmental motivations, and unsustainable-behavior change and the roles of technology therein. The usefulness of multidisciplinary research is emphasized. Finally explicated is psychology8217;s drive and potential for analyzing and supporting environmental sustainability as a long-term human social and economic interest.
