The environmental contingency phase 1 due to ozone has been activated in Mexico City and Edomex for February 16, 2026, to reduce emissions and exposure.
On February 16, 2026, the Commission for Environmental Management of the Megalopolis (CAMe) announced the activation of phase 1 of an environmental contingency due to high ozone levels in the Valley of Mexico. This decision is a response to the recorded maximum hourly concentrations of ozone at monitoring stations in the Tlalpan and Coyoacán boroughs, prompting authorities to take action to protect public health.
The environmental contingency is aimed at reducing both emissions of pollutants and public exposure to harmful air quality. This measure is crucial in a region that frequently suffers from pollution, especially during certain times of the year when atmospheric conditions exacerbate the situation. Continuous monitoring and regulation are necessary to ensure that air quality improves and the health of residents is safeguarded.
Milenio will provide ongoing updates regarding the air quality situation in Mexico City and the State of Mexico, keeping residents informed of the latest developments and necessary precautions during this period of poor air quality. This is particularly important as the pollution levels can lead to severe health risks, especially for vulnerable populations such as children and the elderly.
