The purpose of this volume, bringing together key actors of the well-being community, including scholars and policy-makers, is to advance the understanding and undertaking of the well-being transition away from growth and toward resilience and sustainability, at a time when this progress has become a vital necessity. A decade after the publication of the Stiglitz Report (2009), alternative visions to GDP and growth, that flourished in the 1970s, have re-emerged from all corners of the world, at all levels of governance. Yet, GDP and growth remain very much dominant in defining public policies, influencing businesses and shaping imaginaries.This book moves forward on two urgent tasks that stand before us in order to make progress in the well-being transition: first, connecting well-being to sustainability in a consistent framework highlighting their complementarity, using health as a pivot; second, operationalizing well-being indicators, i.e. integrating them into policy at alllevels of governance.
