The 2050 horizon, with its major challenges—climate change, resource depletion, ageing population, and technological transition—requires us to re-examine what we value in the economy, and what kind of economy we want for the future.

Far from being a purely theoretical exercise, this transdisciplinary report presents four scenarios of what our future might look like, ranging from innovation-driven hyper-growth to more frugal and resilient societies. It also proposes ambitious courses of action to reinvent our accounting tools, our public policies and our vision of progress. It is an accessible and highly topical text that inspires us to reflect — and to act — to build an economy capable of meeting the challenges of life, at the heart of which lies the concept of well-being.
