The SDSN France report attempts to respond to the UN Secretary-General’s recent call for « innovative approaches and bold policy decisions » to tackle the SDGs (UN, 2023). It attributes the existing finance gap to the unrealistic assumptions of the dominant macroeconomic paradigm, which it proposes to replace with new assumptions that are better able to address the sustainability crisis. It then shows that impact materiality enables the deployment of new macroeconomic tools, including the quantification of the SDG financing needs, as well as a series of innovative instruments making it possible to “close the brown money tap”, “open the green money tap”, and « embed money circulation » in virtuous circuits. The potential effects of this new ecological policy mix are analysed using Philia 1.0, an ecological stock-flow consistent model.
Key words : SDG finance, policy-mix.
