Au bord du précipice, opterons-nous pour les monnaies complémentaires locales ?

Noting the risk of collapse of our civilization by 2030 if major trends are not curbed rapidly, this article argues that local complementary currencies could be vectors of real change in the near future. Their potential transforming power appears in the questioning of the monetary and financial system. Indeed, how the money is created and used, by whom and for what is fundamental in formation and propagation of values, beliefs and the evolution of our societies. However, environmental policies currently envisaged take very little account of it. The proposals from the "weak" interpretation of sustainable development, that is to say the one seeking to maintain the current organizational structure, are not up to the challenges. In contrast, the radical reversal of values and lifestyles that would induce the adoption of a "strong" vision of sustainable development does not seem attainable on a short time horizon. Therefore, touching the heart of our organizations, local complementary currencies could make the current monetary system of monoculture to evolve to a world full of diversity, opening channels for the financing of low-carbon activities, and enhancement of behaviors consistent with sustainable development.
