Barcelona reactivates its stringent Low Emission Zone (ZBE) on Monday, 16 March. The city will reinstate traffic restrictions and financial penalties for polluting vehicles after a nearly two-month suspension. This temporary halt aimed to ease the city’s mobility crisis following major disruptions to the region’s commuter rail network.

Authorities originally decided to lift the restrictions on 22 January, responding to chaos on the Rodalies de Catalunya train service. This disruption stemmed from a fatal derailment in Gelida on 20 January and numerous landslides, severely impacting the railway infrastructure. With public transport options crippled, the city council, led by Mayor Jaume Collboni, suspended the ZBE. This move prevented gridlock as commuters turned to private vehicles.
Article 12 of the city’s Low Emissions Ordinance legally permitted this suspension. The ordinance allows such measures in exceptional cases of “duly justified general interest.”
The Return to Normalcy
On Sunday, the Barcelona City Council announced the ZBE’s return, following formal communication from the Generalitat de Catalunya. The Catalan government advised that the “exceptional circumstances justifying its suspension” had ended. Consequently, Mayor Collboni signed the decree restoring the clean air zone to full operation.
During the nearly two-month hiatus, the city experienced a notable shift in traffic patterns. City Council data, reported by Tot Barcelona, showed a 5% increase in private car entries into the city during morning peak hours. Traffic on the city’s main ring roads, the Rondas, also climbed by 2%. Concurrently, the Barcelona Metro absorbed much of the displaced public transport demand, with daily ridership increasing by around 5% during rush hour.
What the ZBE Reactivation Means for Drivers
From 7:00 to 20:00 on weekdays, vehicles without a valid DGT (Dirección General de Tráfico) environmental sticker are once again prohibited from circulating within the designated zone. Drivers violating this regulation face a standard fine of €200. Furthermore, this penalty can increase by 30% during officially declared high-pollution episodes.
The ZBE covers the entirety of Barcelona city, with the exception of the Zona Franca industrial estate and the neighbourhoods of Vallvidrera, el Tibidabo i les Planes. The restrictions also apply to the neighbouring municipalities of L’Hospitalet de Llobregat and Sant Adrià de Besòs, as well as parts of Esplugues de Llobregat and Cornellà de Llobregat.
Some vehicles remain exempt from the rules. These include vehicles transporting people with reduced mobility or specific medical conditions limiting their use of public transport. Emergency and essential service vehicles, alongside foreign-registered vehicles meeting environmental requirements and correctly registered on the official metropolitan registry, are also permitted to circulate.
Broader Mobility Context
The reactivation of the ZBE is a significant step toward re-establishing pre-crisis mobility patterns, but some measures related to the train chaos remain. In a related development, officials confirmed that Catalonia will extend free travel on Rodalies trains until March 31, acknowledging that full service has not yet been restored across the network.
The incident also intensified discussions about the city’s transport infrastructure and environmental policies. It highlighted the fragility of the regional rail network, a system that has seen other recent issues such as the La Garriga rail bridge beam collapse. The temporary traffic increase also serves as a reminder of the ZBE’s role in the city’s long-term air quality strategy, which could see the Barcelona metropolitan area expand its low-emission zones in the future.
