ZFE in Nancy: Everything you need to know about the traffic-free zone (2023)
The ZFE (low-emission zone) in Nancy, implemented since June 1, 2021, during prolonged pollution peaks, utilizes the Crit'Air certificate system to regulate vehicle circulation. This initiative, covering all main roads in Greater Nancy, aims to improve air quality by restricting the movement of vehicles based on their pollution levels, contributing to the city's broader efforts to combat air pollution and prioritize public health.

In an era where environmental concerns take center stage, Greater Nancy has embraced a pioneering initiative to combat air pollution through the implementation of the Crit'Air certificate and the establishment of a low-emission zone (ZFE). Since June 1, 2021, residents and visitors in Greater Nancy have experienced a differentiated circulation system based on the Crit'Air certificate during prolonged pollution peaks. This innovative approach aims to protect the health of the community, especially the most vulnerable, by addressing the significant air pollution challenges posed by the road sector.
Understanding the Crit'Air Certificate in Nancy
The Crit'Air certificate, a national tool utilized in various French cities, plays a crucial role in this endeavor. Affixed to vehicles, this colored sticker indicates the pollution level based on factors such as age and engine type. The system, akin to similar ones across Europe, categorizes vehicles into different classes, promoting awareness and encouraging a shift towards cleaner modes of transportation.
Public Consultation: Shaping Policy Through Community Engagement:
Before the implementation of the ZFE and Crit'Air certificate system, a public consultation was conducted from December 2, 2019, to February 2, 2020. Nearly 570 contributions were received and analyzed, demonstrating a community-driven approach to address concerns and ensure a well-informed decision-making process. The feedback played a pivotal role in shaping the final policies, reflecting the collaborative effort to combat air pollution.
Implementation of Differentiated Traffic:
The differentiated traffic system applies to all main roads in the Metropolis except specified highways (A31, A33, and A330 south of the A33/A330 interchange). However, access to the Nancy-Gentilly and Laxou relay car parks - Sapinière, Vandoeuvre-Brabois, and Parc des Expositions is permitted. This restriction is in effect from 6 a.m. to 8 p.m., aligning with public transport service times. Only vehicles equipped with Crit'Air stickers 0, 1, 2, or 3 are authorized to circulate, with exceptions outlined in the prefectural decree.
Crit'Air Sticker Classifications and Corresponding Vehicles
Understanding which vehicles correspond to Crit'Air stickers 4, 5, and non-class is essential for compliance. These classifications include:
Crit'Air 4: Two-wheelers, tricycles, and quadricycles with engines registered before July 1, 2004.
Crit'Air 5: Diesel cars and light utility vehicles registered before January 1, 2006.
Non-Class: Petrol cars registered before January 1, 1997; Petrol light utility vehicles registered before October 1, 1997; Heavy goods vehicles, buses, and diesel coaches registered before October 1, 2009.
Obtaining the Crit'Air Sticker in Nancy
To navigate Greater Nancy during prolonged pollution peaks, having a Crit'Air sticker is mandatory. Obtaining one is a straightforward process involving online registration through the official website, visiting town halls, or collecting a paper form from the Maison de l'Habitat et du Développement Durable. Priced at €3.70, the sticker is valid for the entire vehicle lifespan and is applicable throughout France.
Alternative Mobilities: Beyond the Crit'Air Sticker:
Encouraging sustainable transportation, public transport on the Stan and Sub networks is free during differentiated traffic days. The initiative extends to other networks within the region, promoting a collective effort to reduce emissions. Carpooling areas on the outskirts of the Metropolis are also designated within a 35km radius, providing further alternatives for eco-conscious travel.
Stay Informed with Email/SMS Alerts in Nancy:
In a bid to keep residents informed, Greater Nancy offers a free email/SMS alert system. This complements the Prefecture's information channels, providing timely updates during pollution peaks. To benefit from this service, residents can register online, receiving notifications a day before the implementation of differentiated traffic.
As Greater Nancy pioneers the Crit'Air certificate and ZFE, the region sets a commendable example of community-driven environmental initiatives. By combining regulatory measures, community engagement, and alternative mobility options, the city aims not only to combat air pollution but also to create a healthier and more sustainable urban environment. The journey toward cleaner air is a shared responsibility, and with initiatives like these, Greater Nancy paves the way for a greener and more environmentally conscious future.
