Abstract: The social and ecological urgency of an ecological transition away from the multi-dimensional crisis of world capitalism is now beginning to win larger acceptance. This article analyzes the role of public banking institutions (central banks, public banking poles, public treasuries) in financing the ecological transition. It successively examines how:
1. The monetization of public investments can restore the role of central banks as agents of sustainable development.
2. By recognizing the power of monetary creation by public financial intermediaries, public financing capacities would be expanded, while dependence on financial markets would be reduced.
3. A renewed policy mix, articulating monetary, fiscal and budgetary policies, must be implemented in order to give priority to the ecological transition and to the fight against climate change.
