This book provides a complete and rigorous overview of environmental topics that may be addressed and, in many instances, better understood by integrating a behavioural approach. This volume features state-of-the-art research on this topic by influential scholars in behavioural and environmental economics, focussing on the effects of psychological, social and cognitive factors on the decision-making process. It presents research performed using different methods and data collection mechanisms (e.g. laboratory experiments, field experiments, natural experiments, online surveys) on a variety of environmental topics (e.g. sustainability, natural resources). This book is a comprehensive and innovative tool for researchers and students interested in the behavioural economics of the environment and in the design of policy interventions aimed at reducing the human impact on the environment.
