Can innovations in business change society? Can innovations in society change business? These two questions have become critically urgent in recent years, but are rarely considered together. ?Business Models for Sustainability Transitions? therefore asks, can contemplating both concepts together result in a flourishing, sustainable future? Technology alone cannot save us. We cannot consciously consume our way out of trouble. This book represents a start at bridging the dynamic world of business model innovation with the constant and unprecedented transitions underway in the world around us. For researchers, practitioners, and policy makers, the coupling of the two questions has the potential to unlock answers to our grand global challenges with responses that are at the same time rapid and enduring. This work offers unique and considered glimpses into what it may take to harness wide-ranging innovations for the collective good.
