Key Points
- • Ardèche placed under orange alert for ozone pollution, effective June 20, 2025.
- • Bouches-du-Rhône activated level 1 ozone alert due to exceeded regulatory thresholds.
- • Emergency measures include reduced speed limits and industrial emission controls.
- • Health recommendations for vulnerable populations to minimize outdoor activities.
France is facing significant ozone pollution challenges as alerts have been issued for multiple regions, including Ardèche and Bouches-du-Rhône, due to elevated air quality concerns. As of June 20, 2025, Ardèche has been placed under an orange alert, prompting Prefect Sophie Elizeon to implement stringent emergency measures aimed at mitigating the impacts of ozone exposure.
The measures in Ardèche include a total ban on burning waste and solid fuel barbecues in residential areas, alongside reduced speed limits on public roadways. The Prefect has also mandated that industrial facilities enhance emission controls, postpone activities that could increase volatile organic compounds or particulate matter emissions, and adopt dust reduction practices on construction sites. Health authorities have advised vulnerable groups to minimize outdoor exertion and stay informed through the Atmo website regarding air quality updates.
In Bouches-du-Rhône, a level 1 ozone alert was activated on the same day, attributed to high ozone levels exceeding regulatory thresholds due to favorable anticyclonic weather conditions. Emergency measures for this department will be enacted starting June 21, involving restrictions across various sectors:
- In transportation, a 20 km/h speed reduction is recommended, with mandatory checks on vehicle emissions.
- Industrial emitters are required to implement emergency control measures as dictated by local regulations.
- Residential advisories include postponing maintenance work that utilizes non-electric tools and limiting outdoor burning activities.
- Farmers are instructed to delay fertilizer applications and outdoor burning as well.
Health advisories also emphasize minimizing strenuous activities for those with respiratory or heart conditions, alongside precautions for vulnerable populations such as pregnant women and seniors.
As these situations develop, the French authorities stress the importance of compliance with health advisories and emergency protocols to protect public health while addressing the ongoing ozone pollution crisis.
