The Comisión Ambiental de la Megalópolis (CAMe) has decided to maintain Phase I ozone air contingency in the Mexico City Metropolitan Area on Saturday, February 14, 2026, marking the third day of vehicle restrictions due to poor air quality. The peak ozone level recorded was 156 ppb at the Atizapán station in the State of Mexico. Authorities attribute the situation to a high-pressure system that promotes pollutant accumulation.
