The document discusses innovative financing solutions for social housing in Europe. It describes how the Île-de-France Region raised over €600 million in socially responsible bonds, over 85% of which came from sustainable investors, to fund social housing and environmental projects at low interest rates. It also discusses the Community Land Trust model in Brussels which purchases land to build permanently affordable housing for low-income residents, maintaining affordable prices by separating land ownership from housing. The solutions aim to provide stable housing while maintaining financial autonomy and resilience for local governments and housing organizations.
