The Environmental Commission of the Megalopolis (CAMe) has declared an environmental contingency in Mexico City and the State of Mexico, leading to the implementation of the Double Hoy No Circula program on February 16. This measure comes in response to recorded ozone levels that reached between 157 and 158 particles per billion (ppb) in areas like Ajusco Medio and Coyoacán, indicating severe air quality issues.

The move to enact a new contingency comes just a day after the previous one was lifted, showcasing the ongoing struggle with air pollution in the region. The southern parts of Mexico City have been particularly impacted, emphasizing the need for immediate action to mitigate health risks associated with poor air quality. The implementation details specify that vehicles with certain holograms will be prohibited from circulating during designated hours.

This escalating environmental situation reveals the persistent pollution challenges faced by urban areas in Mexico, calling for both short-term measures such as vehicular restrictions and long-term strategies to improve air quality. The resumption of restrictions highlights not only the immediate health concerns for residents but also the broader implications for environmental policy and public health responses in the face of recurring air quality crises.
