Air quality

Dunkirk, creative energy to reduce air pollution
Dunkerque est le 3e port Français et un pôle industriel majeur.  La Communauté Urbaine de Dunkerque mène un ambitieux projet de transformation du territoire : « Dunkerque, l’énergie créative » mettra en place une symbiose territoriale urbaine et industrialo-portuaire à impact positif sur l’environnement au travers de 4 axes stratégiques : qualité de l’air, écologie industrielle et territoriale, transition énergétique et intelligence territoriale.
SUEZ a accompagné ce projet dès son origine et se positionne particulièrement sur la problématique de la qualité de l’air. Pour la...
Dunkirk is France's 3rd largest port and a major industrial centre.  The Urban Community of Dunkirk is carrying out an ambitious project to transform the region: "Dunkerque, l'énergie créative" (Dunkirk, creative energy) will set up a regional urban and industrial-port symbiosis with a positive impact on the environment through 4 strategic axes: air quality, industrial and regional ecology, energy transition and regional intelligence.
SUEZ has supported this project from the outset and is particularly focused on the issue of air quality. For the first time in France, a complete solution aimed at significantly reducing air pollution will be implemented, with very ambitious objectives such as going from more than 30 days/year of exceeding the threshold to 0 in 2027, while retaining or even attracting new industrial enterprises. This objective will be achieved by investing in innovative solutions, particularly for the capture of polluting emissions or processing recovered dust.
SUEZ supports local authorities to improve air quality
Chaque année, la pollution atmosphérique coûte 100 milliards d’euros à l’échelle de la France. Les enjeux liés à l’air sont multiples et SUEZ apporte des solutions adaptées pour :
  • Limiter les nuisances olfactives et contribuer au confort des riverains et à l’attractivité des territoires ;
  • Lutter contre la pollution atmosphérique et préserver la santé publique ;
  • Limiter les émissions de gaz à effet de serre et s’engager contre le réchauffement climatique.
Pour faire face à ce défi, le Groupe a décidé d’investir dans la conception, le développement et l’...
Every year, air pollution costs 100 billion euros in France. There are many issues related to air and SUEZ provides adapted solutions to:
  • Limit odour nuisance and contribute to the comfort of local residents and the attractiveness of the area;
  • Tackle air pollution and protect public health;
  • Limit greenhouse gas emissions and combat global warming.
To meet this challenge, the Group has decided to invest in the design, development and operation of innovative air treatment solutions, in France and internationally, such as:
  • The installation of micro-sensors in Santiago de Chile in the heart of the famous "Paseo Bandera" pedestrian street to monitor and analyse air quality (PM 2.5, NOx, CO2, VOC, etc) and monitor public policies in this area;
  • The "IP'Air" experiment, in collaboration with the RATP in Paris, to capture fine particles (PM10 and PM2.5) using a positive ionisation system in underground railway enclosures;
  • The installation of carbon sinks in partnership with Fermentalg, in urban and industrial environments, to transform air pollution into green energy thanks to the power of microalgae combined with the principle of photosynthesis.

Health and urban planning
En matière d’urbanisme réglementaire, l’agence a élaboré dans un premier temps en 2014 un guide « PLU et santé environnementale », qui permet d’identifier à travers 12 déterminants de santé les leviers réglementaires pour intégrer au mieux ces enjeux lors de l’élaboration du document d’urbanisme.
Les 12 déterminants de santé retenus sont les suivants :
  • Alimentation en eau potable et protection de la ressource
  • Assainissement des eaux usées et gestion des eaux pluviales
  • Eaux de baignade
  • Installations classées pour la protection...
In terms of regulatory urban planning, the agency first developed in 2014 a guide called "PLU and environmental health", which helps identify through 12 health determinants the regulatory levers to best integrate these issues into the drafting of the planning document.
The 12 health determinants selected are:
  • Drinking water supply and resource protection
  • Wastewater remediation and stormwater management
  • Bathing water
  • Facilities classified for environmental protection, including livestock buildings
  • Polluted sites and soils
  • Noise
  • Air quality
  • Urban heat islands
  • Power lines
  • Food and local agriculture
  • Physical activity and access to the city for all
  • Degraded habitat
A "vade-mecum" was then carried out in 2019 for the attention of communities in the Nouvelle Aquitaine region, for better consideration of health-environmental issues when developing a Local Intercommunal Urban Planning Plan.
This work is part of the implementation of the RHEP (Regional Health-Environment Plan) in Nouvelle Aquitaine. It summarises the approach by health determinants, and complements it by taking into account a number of regional specificities: population profiles, economic activities, exposure levels and pathologies with suspected or proven links with environmental factors.
In addition, in collaboration with the EHESP (Ecole des Hautes Etudes en Santé Publique de Rennes/School of Higher Studies in Public Health in Rennes), a-urba has also developed a guide for integrating health into development projects (ISadOrA project).
Some 15 "operational keys" have been identified to help developers implement all health issues within the timeline of a development operation.
The results of this study were shared in a working group of 35 stakeholders from both the world of urban planning and health at the national level.
Gran Santo Domingo sustainable urban mobility plan
Mobilise Your City (MYC) est une initiative globale pour le climat qui promeut la planification intégrée de la mobilité urbaine ; elle vise à maximiser le potentiel de réduction des émissions des gaz à effet de serre (-50 % d’ici 2050), en particulier dans les villes des pays du Sud qui accueilleront la majeure partie de la croissance urbaine à venir.
Dans le cadre de cette initiative, le Grand Saint Domingue fait partie des 100 agglomérations qui se sont engagées à définir et mettre en œuvre un Plan de Mobilité Urbaine ambitieux. Cette initiative bénéficie de l’appui technique et financier de l’AFD  (...
Mobilise Your City (MYC) is a global climate initiative that promotes integrated urban mobility planning. It aims to maximise the potential to reduce greenhouse gas emissions (by 50% by 2050), particularly in cities in southern countries that will see most of the future urban growth.
As part of this initiative, Gran Santo Domingo is one of 100 cities that have committed to define and implement an ambitious Urban Mobility Plan. This initiative has the technical and financial support of AFD (French Development Agency) and the MYC programme.
The mission of the SYSTRA group was to support the national authority in charge of planning and improving mobility conditions in the region for 16 months.
This assistance consisted of:
- Providing technical support for the definition of an ambitious action plan,
- Developing digital planning tools,
- Building the capacity of local stakeholders,
- Setting up a participatory process that allows, during the study period, the setting up of real cooperation at the Gran Santo Domingo scale (INTRANT, municipalities, ministries, operators etc).
Planning with nature in the city
Cet ouvrage apporte un éclairage particulier sur la nature en ville, il est centré sur ses effets. A travers un regard pluridisciplinaire, il donne des éléments de compréhension documentés et étayés de chiffres clés sur les effets de la nature en ville, les concurrences et synergies entre phénomènes et les ordres de grandeur des impacts. Les thèmes traités sont en lien avec les leviers de l'aménagement pour des villes et territoires durables.
L'ouvrage s'articule en quatorze chapitres, chacun d'eux est fondé sur une idée préconçue et apporte des éléments de compréhension, des phénomènes en jeu et des effets...
This work sheds particular light on nature in the city, focusing on its effects. Through a multidisciplinary lens, it provides documented, supported elements of understanding of key figures on the effects of nature in the city, competition and synergies between phenomena and orders of magnitude of impacts. The themes covered are related to the levers of development for sustainable cities and regions.
The book is divided into fourteen chapters, each based on a preconceived idea that brings elements of understanding, phenomena at stake and the effects (environmental, health and/or economic) of nature in the city.
Preconceived ideas focus on the effects of nature in the city on biodiversity, air quality, soil quality, sound environment, water management, thermal comfort, greenhouse gas concentration, food, the attractiveness of urbanised spaces and the economic approach. Aimed in particular at the technical services of communities and complementary to the guidelines also proposed for nature-friendly development in the city, it gives the ADEME view of the impact of nature in the city for various issues related to urban planning.
Cooling our cities: what knowledge do we need?
La surchauffe des villes impacte le confort des citadins, et en période de canicule pose un enjeu de santé pour les populations sensibles. C'est pourquoi l'ADEME, soutient le développement de solutions de rafraichissement de la ville qui permettent d'améliorer le confort thermique estival, tout en adoptant une approche environnementale de l'urbanisme.
En 2017, l'ADEME souhaitait initier une réflexion scientifique et technique, en partenariat avec des acteurs externes, permettant de formaliser les résultats clés des travaux de recherche finis, mais surtout d'en avoir une lecture critique afin de dynamiser et...
Overheating of our cities impacts the comfort of city dwellers, and during heat waves poses a health issue for sensitive populations. This is why ADEME supports the development of city cooling solutions that improve thermal comfort in summer while adopting an environmental approach to urban planning.
In 2017, ADEME wanted to initiate scientific and technical reflection, in partnership with external stakeholders, to formalise the key results of the finished research, but above all to have a critical reading of it in order to energise and more deeply research these topics. Following a report on research in the field of urban cooling carried out by the City's Institute for Research in Science and Technology, a science and technology day was organised in Lyon on 27 June 2017. The day brought together more than 50 practitioners and researchers who exchanged views on urban cooling practices and knowledge.
The proceedings of this science and technology day combine a presentation on the state of the art on current knowledge and blind spots in research, the round table interventions that helped highlight operational issues and the work of participants who were invited to explore together, as part of a World Café, the barriers and research avenues that could contribute to ADEME's strategic research operations in this subject.
ArboClimat: the urban tree as a tool to combat climate change
L’arbre urbain est un formidable outil de lutte contre le changement climatique puisqu’il permet à la fois d’atténuer l’impact du volume d’émission de gaz à effet de serre des activités anthropiques de la ville, mais aussi de réduire l’effet de l’Îlot de Chaleur Urbain (ICU), voire de créer un Îlot de Fraîcheur Urbain (IFU). La Région Hauts de France et l’ADEME ont souhaité outiller les collectivités, les aménageurs, les gestionnaires de patrimoine arboré etles élus pour leur fournir un outil leur permettant de réaliser des scénarios de plantation et d’en évaluer l’impact sur la séquestration du carbone et sur le climat urbain...
The urban tree is a great tool to combat climate change as it both mitigates the impact of greenhouse gas emission from the city's anthropogenic activities, as well as reducing the effect of urban heat islands (UHIs), even creating urban cool islands (UCIs). The Hauts de France Region and ADEME wanted to equip communities, developers, tree heritage managers and elected officials to provide them with a tool to carry out planting scenarios and assess their impact on carbon sequestration and the urban climate.

This tool allows you to:

- Assess the impact of existing tree heritage,
- Understand the impact of a planting scenario on carbon storage and UHI control,
- Select species according to several indicators and not just the impact on carbon or UHI control.
Recyclean®: an exclusive process for reusing polluted roads
L’économie circulaire est déterminante pour l’avenir du BTP car elle contribue à préserver les ressources et à mieux gérer les déchets. Elle s’inscrit pleinement dans la transition écologique et l’innovation, deux des piliers du plan stratégique d’Eiffage.
Ainsi Eiffage Route a mis au point Recyclean®, un procédé exclusif de réemploi des chaussées polluées, notamment par des hydrocarbures aromatiques polycycliques (HAP) qui s’inscrit pleinement dans cette stratégie. Recyclean® permet de régénérer ce type de chaussées et de retraiter les matériaux existants. Cette solution ne génère pas de déchets, ni de...
The circular economy is crucial for the future of construction because it helps preserve resources and better manage waste. It is fully in line with the ecological transition and innovation, two of the pillars of Eiffage's strategic plan.
So Eiffage Route has developed Recyclean®, an exclusive process for reusing polluted roadways, including polycyclic aromatic hydrocarbons (PAHs), which is fully part of this strategy. Recyclean® allows this type of roadway to be regenerated and existing materials to be reprocessed. This solution generates no waste or landfill costs for polluted materials and fully meets the Energy Transition for Green Growth Act (LTECV) of 2015, which aims, among other things, to reduce the amount of waste admitted in storage facilities by 30% by 2020 compared to 2010, and 50% by 2025.
Ecologically and socially virtuous, the Recyclean® process avoids using new materials on construction sites as well as movements of trucks loaded with polluted materials. Recyclean® is also more economical because it avoids both the transport and the systematic landfilling of these materials.
