This book examines how circular economy principles and net-zero strategies can drive sustainable growth in emerging markets, with a focus on Sub-Saharan Africa, Southeast Asia, and Latin America. It addresses the distinct challenges and opportunities these regions face in advancing low-carbon, resource-efficient development. Integrating perspectives from digital technologies, corporate strategy, finance, and public policy, the book offers a practical roadmap for governments, businesses, and development actors. Key themes include the role of disruptive technologies, innovative financing mechanisms, and policy frameworks in accelerating sustainability transitions. Drawing on international policy analysis and case studies from both emerging and advanced economies, the book presents actionable insights across sectors such as food systems, smart cities, and corporate decarbonisation. Aligned with SDG 9 (Industry, Innovation and Infrastructure) and SDG 13 (Climate Action), this volume is an essential resource for scholars, policymakers, and practitioners advancing circular and net-zero transformations.
