Air quality in Toulouse: what you need to know
Toulouse, the Pink City, France's fourth-largest municipality with nearly 500,000 residents, enjoys a generally favorable air quality profile. The semi-oceanic climate with Mediterranean influences promotes pollutant dispersion. However, the aerospace industry (Airbus, ATR) and heavy road traffic on the ring road and arterial roads are significant pollution sources. Neighborhoods near the Canal du Midi and the Garonne river enjoy better air quality. The historic center, largely pedestrianized, also shows good results. Peripheral areas near road corridors and industrial zones in Blagnac and Colomiers rank lower. Toulouse Metropole is actively expanding its metro and tram network to reduce car dependency. The average score of 68/100 places Toulouse among France's best-ranked major cities.

Properties in the pedestrianized historic center gain value through a living environment that includes good air quality. An ImmoGrade report highlights these advantages compared to environmentally less favorable neighborhoods.
