Background and Relevance of the Comisión Ambiental de la Megalópolis (CAMe)
The Comisión Ambiental de la Megalópolis (CAMe) is a crucial environmental organization responsible for monitoring and managing air quality in the Mexico City Metropolitan Area (MCM). Established to address environmental challenges faced by the densely populated region, CAMe plays a vital role in ensuring the well-being of its 22 million residents.
The Current Situation
On this Friday, CAMe has declared a Stage 1 atmospheric environmental contingency for ozone in the Zona Metropolitana del Valle de México (ZMVM). The air quality is classified as “POOR” due to a high-pressure system influencing the region for the past two days. This has resulted in moderate to strong atmospheric stability, weak winds, and intense solar radiation that favors ozone formation and accumulation.
Details of the Contingency Measures
To mitigate public exposure to contaminated air and reduce emissions, CAMe implemented the “Doble Hoy No Circula” (Double No Driving Day) measure on the afternoon of January 8th. This initiative aims to decrease pollution levels by restricting vehicle circulation based on their hologram verification numbers.
Which Vehicles are Restricted on January 9th?
- Private vehicles with verification hologram 2.
- Private vehicles with verification hologram 1, where the last numeric digit is 2, 4, 6, 8, 9, or 0.
- Private vehicles with verification hologram 0 and 00, blue sticker, and plate endings of 9 and 0.
- Vehicles without a verification hologram.
- Antique, demonstration, or new vehicles with a tourist pass.
- Vehicles with foreign plates or plate formations of letters face the same restriction as vehicles with hologram 2.
- 50% of LPG (Liquid Petroleum Gas) delivery trucks to stationary tanks without dry disconnect valves, with plate endings of PAR.
- Local or federal cargo vehicles must stop circulating between 6:00 AM and 10:00 AM, except those enrolled in the Mexico City or State of Mexico Self-Regulation Programs.
- Taxis with verification holograms “00”, “0”, “1”, or “2” must adhere to the driving restrictions from 10:00 AM to 10:00 PM.
Key Questions and Answers
- What vehicles are restricted from circulating on January 9th? Private vehicles with specific hologram verification numbers, antique or new vehicles, LPG delivery trucks without dry disconnect valves, and taxis with certain verification holograms are restricted.
- What is the purpose of the “Doble Hoy No Circula” measure? The initiative aims to decrease pollution levels by restricting vehicle circulation, thereby reducing public exposure to contaminated air.
- What factors contribute to the current poor air quality? A high-pressure system influencing the region for two days has resulted in moderate to strong atmospheric stability, weak winds, and intense solar radiation that favors ozone formation and accumulation.
- When will CAMe provide an updated air quality report? CAMe will issue an updated report at 8:00 PM on Friday, detailing the air quality and meteorological conditions.
CAMe advises the MCM population to stay informed about air quality and avoid exposure during peak contamination hours (1:00 PM – 7:00 PM).
