A Sustainable Creative City

Mis à jour :

The Grand Paris is a development project for the whole of the Paris metropolitan area. It is designed to improve residents’ quality of life, address regional inequalities and build a sustainable city.

The Grand Paris aims to be the city of the future: sustainable, creative and solidarity-based. It will make the Île-de-France an attractive 21st century metropolis.

The project is supported by the State and the Ile-de-France – a region of 12 million inhabitants that accounts for almost a third of French GDP – and provides a splendid opportunity to involve all city stakeholders including developers, transport operators, public and private investors, construction companies, architects, urban planners and all Greater Paris residents.

At the heart of the scheme lies an ambitious project to modernise the existing transport network and create a new automatic metro – the Grand Paris Express.


Significant urban projects will emerge along this transport route: new neighbourhoods with an array of features including housing, economic activities, university centres and cultural facilities – especially around the strategic, structural points provided by the stations. The idea is to enable business clusters to take root while rebalancing the Paris region, opening it up to its more remote, isolated areas.

The Grand Paris Express consists of a ring route around Paris (line 15) and lines that serve developing neighbourhoods (lines 16, 17 and 18). The Grand Paris Express will also involve extending existing metro lines.

A dedicated Project Manager with the right skills

The SGP is a public agency overseen by the Ministry for Housing and Regional Equality, the Ministry for Ecology, Sustainable Development and Energy and the Ministry for Finance and Public Accounts.

Tasked with designing and implementing the future transport network, the Société du Grand Paris is building “new generation” stations alongside real estate projects that could help new neighbourhoods emerge in the Paris metropolitan area.

The Grand Paris Express will mark a break with the way the Paris transport network operates, creating new patterns of mobility by making travel between the suburbs easier. In enabling regional areas to engage in dialogue both with each other and with Paris, the Grand Paris Express will provide businesses with numerous opportunities for economic development.

The Société du Grand Paris plans to use land holdings earmarked for infrastructure near or overlooking the stations to develop additional real estate projects that will provide housing, economic activities and other facilities. This approach is in line with aim to make the station part and parcel of the urban fabric and will help with the construction of new mixed neighbourhoods.

The Société du Grand Paris is thus making its land holdings available for the development of urban projects and helping to deliver on calls to build more densely around stations.

With €300 million invested in the first 33 kilometres of the network in 2013, the Société du Grand Paris is proceeding apace with the creation of the future metro. The first construction sites will open in 2015 and are expected to generate 15,000 to 20,000 new jobs per year. In addition to these construction-related jobs, the arrival of the Grand Paris Express will create between 115,000 and 315,000 additional jobs.

Three levels of governance

The Société du Grand Paris is governed by three complementary bodies.

• The Supervisory Board constantly monitors the way the Management Board runs the Société du Grand Paris. It comprises 21 members representing State and local government authorities. The Supervisory Board’s responsibilities include approving the SGP’s general policy guidelines, its financial management and its development or construction operations programmes.

• The Management Board is responsible for running the Société du Grand Paris, under the supervision of the Supervisory Board. Its three members take a consensus-based approach, with one member being appointed as Chairman :

  • Philippe Yvin: Chairman of the Management Board, in charge of managing the Société du Grand Paris and implementing the overall scheme and related development and building programmes.
  • Frédéric Brédillot: Member of the Management Board, in charge of cross-company functions, particularly financial and legal issues, human resources and general affairs.
  • Bernard Cathelain: Member of the Management Board in charge of programme design and delivery for the transport project, and responsible for industry and procurement.

• The Strategic Committee is the SGP’s forum for discussion, proposals and continuing consultation. It assists the Management Board with direction and decisions relating to the creation of the Grand Paris Express network. It currently comprises 139 members who represent the municipalities through which the Grand Paris Express network will run, 4 Members of Parliament and representatives of socio-economic stakeholders. It acts as a think tank and discussion forum for elected representatives from the Île-de-France communities and Société du Grand Paris partners.


In brief

Le Grand Paris Express should simultaneously:

  • Relieve the RER and existing transport systems
  • Reduce congestion and car pollution
  • Combat urban sprawl and agricultural encroachment
  • Promote the economic development of the Ile-de-France Region
  • Contribute, by ripple effect, to the competitiveness of France as a whole


By 2030:

  • 205 km of automatic metro lines will have been built;
  • 68 new stations will connect the Grand Paris clusters with the three airports and TGV stations;
  • 2 million passengers will travel on this new network every day;
  • Journey times will be significantly reduced, especially from suburb to suburb, with ring routes and trains traveling at 55 to 60 kilometres per hour (average operating speed).
