Toulouse is one of the cities that are concerned by the Plan for the Air Protection (“Plan de protection de l’air” in French). It did also commit in the “breathable cities in 5 years” project and plans to implement an environmental zone in order to exclude the more polluting vehicles from the traffic during pollution peaks. According to the previsions, the area should cover the inner ring road. The project foresees a speed reduction of 20 km/h in alert state. More information is expected by the end of the year.
