To build a fair, progressive and sustainable city, knowledge of the local community is one of the greatest resources and the most important means of exchanging and discussing thoughts. This requires the city's tools to help city dwellers easily contribute to larger and smaller projects. The aim of the "Madame Mayor, I Have an Idea" digital platform is to encourage the widest possible and open participation. On the project website, all residents of Paris are invited to share their ideas and project proposals with the city. The ideas submitted can be discussed, developed and revised together. Funding for projects is financed through a participatory budget: the digital platform allows Parisians to select projects that are proposed by the community each year and which will be financed by 5% of the city's annual investment budget.
