This book explores the impact of our consumption habits on the planet and how global crises can transform them. Connecting climate policy, sustainable development, and consumer behavior, it offers a clear framework for understanding responsible consumption. Additionally, the book examines EU climate targets, circular economy principles, and the role of digital commerce in shaping environmental outcomes.  Through an analysis of five major global crises ranging from the 1973 oil shock to the current climate emergency, the book illustrates how recent disruptions, such as the pandemic and the Russo-Ukrainian War, can prompt more conscientious choices while revealing the obstacles to lasting change. With real-world case studies and evidence-based policy insights, the book provides researchers, policymakers, and individuals interested in climate action with theoretical insights and practical tools.
