Actions are to be planned

Via regulatory means and through plans, actions for maintaining or improving air quality are to be planned.


These plans are developed largely at the level of a Region or conurbation and all share the basic principle of consultation aimed at bringing together various local opinions and skills in order to enrich discussion and reflection and find consensuses accepted by all parties.

Des plans pour une meilleure qualité de l'air


The Programme de Surveillance de la Qualité de l’Air (PSQA – Air Quality Monitoring Programme) is derived from the  inter-ministerial order of 17/03/03 relative to methods for monitoring air quality and informing the public (Official Gazette No. 167 of 22 July, 2003) (modified by the Order of 25 October, 2007).

Each approved air quality monitoring association is requested to provide the Ministry for Environment with a program describing its monitoring strategy; this strategy must take into account both European and national regulations and local specificities.
 The PSQA is a document that must be reviewed every five years.


an inventory of knowledge

The Regional Air Quality  Plan (heading II of the LAURE - Decree of 06 May 1998 ) consists of an inventory of knowledge but also ignorance of all areas, near or far, relating to air quality. Within it  there are obviously industrial or automotive traffic emissions but also those from the residential and tertiary sectors or agriculture. The health and environmental aspects are also studied and as well as ways of communicating. Compliance or non-compliance with national air quality objectives is discussed and recommendations follow to prevent or reduce air pollution and its effects.

a common work 

The application of PRQA is not a regulatory requirement; it has value in showing trends. The law provides for its revision every 5 years. The PRQA was updated in 2010; the work was done in common with the Haute-Normandie and Basse-Normandie Regional Councils. 

integrated into the Regional Plan for Climate, Air and Energy

The PRQA is to be subsequently integrated into the Schéma Régional Climat Air Energie (SRCAE – Regional Plan for Climate, Air and Energy), which came out of the “Grenelle de l’environnement” conferences (2007) and the resulting “Grenelle I” and “Grenelle II” laws. The SRCAE is conducted by the Regional Prefect and the President of the Regional Council, in consultation with stakeholders, to define quantitative and qualitative goals at the scale of each Region, taking economic and social aspects into account. 


Plan for the Protection of the Atmosphere  (heading III of the LAURE - Decree of 25th May 2001), This is mandatory for all towns of more than 250,000 inhabitants and in all areas where pollution levels exceed or may exceed the legislative values (limits).The pollutants covered are primarily those that are regulated such as sulphur dioxide, nitrogen dioxide, particulate matter, lead, carbon monoxide and benzene. Other pollutants can also be included but outside a regulatory basis. Upper Normandy decided to focus also on volatile organic compounds and heavy metals and odors.
The application of the PPA tends to find values below the thresholds. It is realized through temporary or permanent measures that may affect the functioning and operation of certain categories of facilities, use of vehicles, the control of pollutant emissions ...

Led by the State, 3 PPA are revising in Upper Normandy

Those relate to:

  • Greater Rouen,
  • the Le Havre conurbation,
  • and the Port-Jérôme zone (cantons of Lillebonne and Quillebeuf sur Seine).

In the Basse-Normandie Region, no PPA was deemed necessary in light of the levels of regulated pollutants.


Urban Journeys Plan  (heading V of LAURE - circular dated November 08, 1999 ) has a clear objective, written in black and white: "reduce automotive traffic", have less room for cars in town in favour of other modes of travel that are less polluting, such as cycling or walking. Public transport is not forgotten and must be developed, travel between home and work to be rethought as well as the transport and delivery of goods. This consideration, heavy in terms of urban planning, infrastructure and lifestyle, is compulsory for all agglomerations of more than 100,000 inhabitants.

Rouen city adopted its PDU on February 11th  2000 and the Community of the Le Havre Agglomeration did this on March 18th  2003. Caen conurbation adopted its PDU on April, 2001.
