Encouraging Pro-Environmental Behavior: What Works, What Doesn't, and Why examines the main drivers of human behavior related to environmental sustainability and how we can encourage environmental behavior change in humans. The book explores the underlying barriers and enablers of environmental behavior and outlines key theoretical advances from psychology to improve understanding. It then uses theory-based research in the development of behavior change interventions to critically evaluate empirical evidence on the effectiveness of those interventions. This book will help inform and improve the success of behavior change initiatives to mitigate climate change.
