Solidarity finance and sustainable development: what link?[Finance solidaire et développement durable : Quel lien ?]

Since the 1980s, modern finance has seen many innovations. However, most of these were not always created to support the real economy to improve the standard of living of marginalized populations, but often to create income markets. The objectives of solidarity finance are intrinsically social. Popularized by the Brundtland report, sustainable development is one of the most important challenges of the 21st century; the importance of this challenge is essentially due to the need to meet social, economic, and environmental needs. To fully understand and appreciate the importance of solidarity finance, it becomes imperative to take stock of its different definitions to understand its essence, to explore their underlying logic, their contribution to the creation of value and the sustainability of the share capital. «These initiatives, to promote access to finance, are at the origin of alternative financial logics: the logic of sharing, the logic of mutualisation and the logic of assistance » (Artis, 2015)
