Frequently Asked Questions

What is an Air Quality Certificate?

  • The certificate is a round sticker that must be displayed in a prominent position on your vehicle. It is a secure document.
    There are 6 different types of certificates.
    Each certificate corresponds to a vehicle class defined according to air pollutant emissions.
    Older vehicles covered by less stringent emissions standards are not eligible for a certificate.
    This website is the official site for issuing Air Quality Certificates.

  • For eligible vehicles, the Air Quality Certificate is mandatory for:
    - Driving and parking in restricted traffic zones (french low emission zones) designated by the authorities, such as inside the Paris ring road
    - Driving in case of access regulation if an emergency scheme have been implemented by prefects during pollution episodes. This may be the case in the Grenoble Metropolitan Area, in Lyon-Villeurbanne and in the Greater Paris Region inside the motorway A86

    It is for all road vehicles, including cars, heavy goods vehicles, buses, coaches, two-wheeled vehicles, commercial vehicles, etc., except agricultural and construction machinery.

    An Air Quality Certificate must be affixed even for vehicles and uses that are exempt from restricted traffic zone (french) low emission zone and access regulation implemented by emergency scheme.

  • A vehicle retains the same environmental classification throughout its lifetime.
    Once acquired, the certificate is valid as long as it remains legible.

    The ink and materials used for the certificate have been chosen to last as long as possible.
    During the technical inspection, the legibility of the certificate will be checked and a replacement may be requested, if necessary.

  • The Air Quality Certificate indicates the vehicle's level of pollution. The higher the certificate number, the more polluting the vehicle is.
    As such, in the most polluted areas or during pollution peaks, Air Quality Certificates encourage use of the least polluting vehicles and limit use of the most polluting vehicles. To learn more about the provisions in effect, contact the town hall or prefecture.

    In France, air pollution is a major health issue: nearly half of the French population breathes air in which atmospheric pollutant levels exceed current health standards.

    The health impacts of pollution are known: they can be immediate or long-term (respiratory problems, asthma, cardiovascular diseases, cancer, etc.). The French National Public Health Agency estimates that air pollution causes 48,000 early deaths every year (2016 figure), potentially reducing life expectancy by more than two years. In October 2013, the World Health Organisation (WHO) classified outdoor air pollution as officially carcinogenic for humans.

  • The certificate takes into account local air pollutant emissions and mainly the fine particles and nitrogen oxides (NOx) emitted from vehicle exhaust pipes. These pollutants have a direct impact on people's health, especially those living near very busy roads.
    The certificates are based on the "EURO" standards. These are European standards which set pollutant emission thresholds for new vehicles sold. These standards are tightened on a regular basis.
    The certificate does not take into account greenhouse gas emissions which are a global, not a local, issue and which do not directly affect our health. This issue is dealt with elsewhere.

  • Air quality certificates help to fight against local pollution caused by pollutants, including fine particles and nitrogen oxides, that are dangerous to human health.
    Bonus-malus systems or a CO2 surtax aim at fighting climate change by reducing greenhouse gases. These measures do not have a local, short-term impact but rather a long-term impact on a global scale.
    There is no correlation between fine particle and nitrogen oxide emissions and greenhouse gas emissions. Whilst greenhouse gas emissions are directly linked to fuel consumption, this is not the case for fine particle and nitrogen oxide emissions which are heavily related to the engine configuration and the performance of emission control systems (particle filter, catalytic conversion systems, etc.). It is, therefore, not unusual for a vehicle to be awarded different classifications for air pollution and greenhouse gas emissions.

  • The Crit'air vehicle classification is defined by the order of 21 June 2016 establishing the coding of vehicles classified by their air pollutant emission level pursuant to article R. 318-2 of the French highway code.

    Finding out my vehicle's classification

  • YES. The classification is identical nationwide.
    On this basis, depending on the local situation each local authority can decide to implement incentives or restrictions and define the vehicles concerned. Road signs will be set up so that the scheme is clear for all users.

  • This classification firstly identifies vehicles based on their category (two-wheeled, cars, commercial vehicles, heavy goods vehicles).
    Within each of these vehicle categories, each vehicle is assigned an environmental class, from the lowest emitters of air pollutants (electric or hydrogen class) to the highest emitters (category 5 and not classified). This environmental class is assigned depending on the type of energy and fuel (electric, diesel, petrol, etc.) and the vehicle's EURO standard (or by default the initial registration date). The EURO standard, introduced by the European Union, sets constrictive standards for manufacturers, which are required to bring the least polluting vehicles to the market.
    Electric vehicles do not emit any exhaust pollutants and have a positive classification.
    Vehicles with an internal combustion engine (petrol, diesel, etc.), which are a major contributor to air pollution by emitting particles and nitrogen oxides, are classified from 1 to 5 or are not classified. Thanks to tighter regulations, the latest vehicles feature more effective pollution control technologies (catalytic converters, particle filters, etc.) and therefore pollute less.
    Vehicles that run on several energy sources (hybrid for example) are classified based on the pollutant emissions of their main fuel.
    The Air Quality Certificate or Crit’air classifies motor vehicles according to their level of pollution.
    Lastly, the technical inspection ensures that the vehicle does not have any significant failures, particularly concerning its air pollutant emissions.

  • The following are subject to penalties:
    o Use of a fraudulent certificate
    o Use of an illegible certificate or a certificate that is not visibly affixed*
    o Not observing traffic restrictions in restricted traffic zones or during differentiated traffic periods (pollution episodes)
    o For eligible vehicles, parking in a permanent restricted traffic zone without an Air Quality Certificate

    The penalties and amounts are stated in articles R318-2 and R411-19-1 of the French highway code.
    Failure to observe traffic restrictions in a restricted traffic zone is subject to a class 3 fine for light vehicles (€68 single fine) and a class 4 fine for heavy goods vehicles (€135 single fine).
    Failure to observe the differentiated traffic rules implemented by prefects during pollution episodes is subject to a fine for failure to comply with a prefectorial order.
    Fines will not initially be issued for failing to have a certificate to give users time to obtain one.

  • The price of the certificate only covers the costs of the service issuing it, namely the service development, maintenance and operations, as well as the costs for developing, manufacturing, delivering and tracking the certificate applications.
    It is not a tax and the State budget does not receive any revenue from it.
    The price of the certificate is being reduced from 1 March 2018. For shipment abroad, the price will be €3.11 plus the cost of postage instead of €3.70 plus the cost of postage.
    The price for issuing an air quality certificate is set by the Decree of 14 February 2018 which modifies the Decree of 29 June 2016.
    Pursuant to the General Terms of Use which you have accepted, the prices of the Certificates are those in force at the time the order is placed. Consequently, orders placed before 1 March 2018 will not result in a refund to take account of this price reduction.
    Be careful : fraudulent websites (not affiliated with the "Ministère de la Transition écologique et solidire") offer the Crit'Air label at far higher prices.

  • This site is defined as the official site by the order of 29 June 2016 concerning the issuance and affixing of Air Quality Certificates, which identifies the site as the only way to remotely submit Air Quality Certificate applications.

  • The certificate contains various protection elements: microlettering, an individual 2D-DOC data matrix (QR-code), etc.
    The certificate is also weakened: once it is stuck on, it cannot be taken off without tearing.

  • The 2D-DOC data matrix is a security technology recognised by the Interior Ministry. It contains non-personal and non-confidential information specific to your vehicle, as well as an electronic signature confirming its authenticity.
    It can therefore be checked quickly and efficiently.
    The 2D-DOC data matrices can be read on smartphones using a free application.

Do I need an Air Quality Certificate ?

  • For eligible vehicles, the Air Quality Certificate is mandatory for:
    - Driving in restricted trafic (franch low emission zones) designated by the authorities, such as inside the Paris ring road.
    - Driving in case of access regulation if an emergency scheme have been introduced during pollution episodes.
    The certificate also gives you certain benefits set up by local authorities.
    An Air Quality Certificate must be affixed even for vehicles and uses exempt from restricted traffic zone (french low emission zone) and access regulation implemented by emergency scheme.

  • It is for all road vehicles, including cars, heavy goods vehicles, buses, coaches, two-wheeled vehicles, commercial vehicles, etc.
    It does not apply to agricultural and construction machinery.

  • YES. An Air Quality Certificate must be affixed in applicable situations, even on vehicles that have a disabled person's parking card. However, people with a disability are not affected by traffic restrictions.

  • An Air Quality Certificate must be affixed in applicable scenarios, even for vehicles and uses that are exempt from low emission zone and access regulation.

  • It is covered by the least stringent anti-pollution standards, which result in more polluting technologies. It is therefore not eligible for a certificate or traffic benefits.

  • The regulation does not cover responsibility for purchasing, which is determined by the lessor-lessee relationship.
    If a penalty is issued, it is given to the driver of the vehicle.

I'd like to find out my vehicle's classification

  • Our reckoner allows you to identify the Air Quality Certificate your vehicle is entitled to.
    Important: the label shown in the reckoner is only an example and has no contractual value.

  • The vehicle's Euro standard is indicated in the "V.9" field of your registration certificate.
    However, this field is included only on recent EU registration certificates.
    If so, your vehicle will be classified according to its initial registration date, which in the vast majority of cases produces the same classification.

    However, in rare cases the vehicle's EURO standard is higher than the standard in effect on its initial registration date (early adoption of the standard). This may allow the vehicle to obtain a higher Crit'air classification. If this situation applies to you, you must have your registration certificate updated before submitting an Air Quality Certificate application.

  • In the "reckoner" tool, a two-letter code appears in the energy "bubbles" when you hover your mouse over them for a few moments.
    Please use the code matching your energy source from the following list.
