Sustainability today is not simply a constraint or compliance issue – it is an innovation process that redefines how companies conceive their value proposition, organize supply chains, engage stakeholders, and govern transformation. This book places business models at the center of that redefinition, framing Business Model Innovation (BMI) as a critical lever to align economic performance with social and environmental value creation. Bridging academic rigor and practical relevance, this volume offers an integrated perspective on sustainability, innovation management, and digital transformation. This book targets students, researchers, managers, entrepreneurs, and policymakers working to understand and shape a new generation of business models that meet the demands of a turbulent world – models that are sustainable, digitally enabled, and built for meaningful impact.
