Air Pollution Advisory Activated in Lyon Due to Elevated Particulate Matter Levels

On January 19, 2026, the Prefect of Rhône activated the "information-recommendation" level of air pollution alert for the Lyon metropolitan area and the entire Rhône department. This step was taken in response to stable, low-dispersive weather conditions expected to cause an increase in fine particulate matter, notably PM2.5, leading to degraded or poor air quality in central and eastern urban areas around Lyon.

While no mandatory restrictions have been imposed, several measures and recommendations have been issued to protect public health and limit further pollution. Vulnerable populations are advised to reduce outdoor intense physical activities and limit travel on major roads during peak hours. The general population is encouraged to adopt behaviors such as minimizing use of wood-burning heating appliances, controlling indoor temperatures, favoring less polluting transportation modes, adjusting work schedules, and endorsing teleworking.

Authorities have also enforced a ban on burning green waste and usage of open fireplaces within Lyon metropolis. Additionally, certain vehicle classes are prohibited from circulating in the Low Emission Zone to curb emissions. Local governments, farmers, and industrial operators are urged to reduce dust-generating construction activities and postpone any burning operations.

Residents seeking more information and updates on air quality can consult the AASQA website. These measures aim to mitigate pollution spikes under current meteorological conditions and safeguard public health during this period.
