This study was carried out in December 2017 by the French Ministry of the Environment, the ADEME, and the French Ministry of Agriculture and Food to address the challenge of soil artificialisation. Public authorities have therefore requested the joint scientific expertise of IFSTTAR and INRA to put forward a review of available scientific knowledge on the causes and consequences of soil artificialisation, as well as the levers of action that make it possible to limit its expansion and/or environmental impacts.
Based on the analysis of the 39 French EcoQuartier labelled operations in 2013, 2014 and 2015, located in most of the major French regions, Cerema's publicaton "EcoQuartiers, what lessons can be learned?" aims to overcome preconceived ideas and develop collective representations. What is really new in these projects? What is the difference between a 1970s or 1980s development project and today’s so-called "sustainable" urban projects?
The global context of increasing population and decreasing resources and raw materials requires us to reflect on the transition from a linear to a circular economy. With more and more inhabitants living in cities, the challenge of circularity is above all urban. Town and country planning must contribute to this by restricting silo-based approaches and acting in an integrated way, so that all the territory’s resources are mobilized for a single objective: to turn our territories and cities into sober and decisively circular spaces.
Amsterdam has made sustainable mobility a key feature of its brand, as shown in the stunning images of bike highways across the country. Today, every city is angling to become as bike-friendly as the Dutch capital. Paris is also pursuing this dream, overshadowing the fact it is already the world champion for an even more sustainable form of mobility: walking.
The Reference Framework for European Sustainable Cities (RFSC), which was made available free of charge for European cities and local authorities at the beginning of 2013, provides a reference framework for the development of territorial strategies and urban project that, in an integrated fashion, takes the four pillars of sustainable development into account. As the result of four years of work between 17 different countries, of which Cerema was the technical backbone, the RFSC offers online support for the implementation of sustainability principles in local policies and actions.
The Santiago Deseado 3D simulator, which was handed over to the Municipality of Santiago in June 2015, is a decision-support tool to aid the formulation of sustainable urban policies. Financed by the French government and created by a consortium of companies headed by Artelia, it compiles a large quantity of data on water and waste management, public infrastructure, transportation, the social distribution of inhabitants, telecommunications, etc. to form an interactive map.
Assessment is a determining principle of the AEU2 ( French acronym standing for Environmental Approach for Urban Planning 2) ; the assessment process integrated in a cross-cutting way into the planning project helps understand and better qualify the values of this project. Evaluation is not an end in itself but a means to achieve the perpetual improvement of a project or planning practices.

The municipality waged a relentless battle over the course of a year to defend a former wetland, in order to preserve its biodiversity and avoid an ecological disaster with irreversible damage for nature, people and health. A private company and local stakeholders were running a harmful project of inert waste storage in this area, which was eventually dropped under the pressure of citizen mobilization and actions led by the city and its supporters.
Each year, more than one million tonnes of nitrogen oxide (NOx) is produced in France, almost 50% of which is produced from vehicle exhaust gases. Recognised as hazardous to health, these gases are at the root of many respiratory problems, especially in frail people. To address this issue and this public health challenge, Eurovia (a subsidiary of VINCI) has developed a unique and innovative process, NOxer®.
The "Tools for development" website is intended primarily for local elected officials, technicians from local authorities and other stakeholders in development, to whom it provides information on tools and methods mainly in the fields of land, operational and regulatory urban planning, the environment and housing. It constitutes a technical database of more than 250 tools accessible according to seven main themes and nearly 35 operational issues, thus answering the territory's stakeholders' most pressing questions.
