MEXICO CITY — On February 28, 2025, the Metropolitan Environmental Commission (CAMe) confirmed the lifting of phase 1 of the air quality contingency due to improved conditions, which means the Hoy No Circula program will operate normally.
The contingency was lifted on February 27 at 6 PM following reports indicating reduced levels of atmospheric ozone, as stated by CAME. This adjustment signals to residents and commuters across Mexico City and the State of Mexico (Edomex) to resume regular transit plans though with precautionary measures still advised for air quality.
According to data from the air quality monitoring system, the previous high levels of ozone were largely attributed to unfavorable meteorological conditions, including atmospheric stability and weak winds. The latest reports indicated the area would see increased humidity, leading to clearer skies, which is expected to improve the dissipation of air pollutants.
"La Comisión Ambiental de la Megalópolis (CAME) confirmó que levantó la fase 1 de contingencia ambiental por ozono...", as reported by the Commission. They stressed the need for continued vigilance as air quality and climatic conditions can change rapidly.
With the retraction of the contingency, the Hoy No Circula program also resumes typical operations, scheduling specific days wherein certain vehicles are banned from circulating based on their license plate numbers and the color of their verification stickers. For February 28, vehicles with blue stickers who have license plates ending with 9 or 0 will not be permitted to circulate.
Notably, the Hoy No Circula program includes exceptions for:
- Electric and hybrid vehicles
- Vehicles with valid zero-emission stickers
- Public transport, emergency vehicles, and vehicles for people with disabilities
- Other authorized transport including school buses and funeral services.
For drivers who fail to comply with the restrictions, fines range from 2,171.4 pesos to 3,257.1 pesos for violating Hoy No Circula rules, alongside potential towing fees. Noncompliance can be costly, especially for those driving vehicles subject to restrictions.
Residents and drivers are encouraged to stay informed about air quality through resources provided by the commission, including their official websites, which offer real-time data and updates. Such monitoring helps maintain public awareness about the air quality and health risks associated with prolonged exposure to pollutants.
“Para mañana ingresará al Valle de México mayor humedad...,” emphasizes the need for continuous weather updates from the environmental authorities to inform the public about potential future contingencies.
Implementation of the Hoy No Circula program has been met with varied sentiment among drivers; many acknowledge its necessity for combating pollution, whereas others express frustration over its impact on daily commuting. Nonetheless, the program’s framework is seen as integral to improving overall air quality and, by extension, public health.
For residents and visitors to Mexico City and its surroundings, adherence to these guidelines remains pivotal, not just to avoid fines but also to contribute toward cleaner air. A community commitment to supporting these initiatives will be pivotal as authorities remain watchful of impending weather changes and their associated impacts on air quality.
Monitoring efforts will persist, ensuring regulations adapt quickly to changes in air quality and meteorological situations. The collaboration between the government and citizens is fundamental to making strides toward sustainable air quality management. The situation is dynamic, and preparedness is key for both the authorities and the community.
