Vehicle inspection procedures in Mexico City and the State of Mexico could undergo significant changes starting in 2027. A new initiative has been proposed to modify the criteria for assigning ‘Cero’, ‘Doble Cero’, and ‘Exento’ holograms, which dictate vehicle circulation restrictions in the Metropolitan Area of the Valley of Mexico.
New Environmental Standards Proposed
The proposal, introduced by the Mexican Climate Initiative (ICM) and currently under review by the Environmental Commission of the Megalopolis (CAMe), aims to align vehicle classification more closely with actual environmental impact. According to the ICM, the current system relies too heavily on vehicle age, which does not always accurately reflect how much a vehicle pollutes.
Key Proposed Changes
The initiative suggests incorporating three new parameters for vehicle evaluation:
- Fuel Efficiency: Energy efficiency and consumption rates will be considered.
- Evaporative Emissions: Measurement of pollutants released during fuel evaporation.
- Certified Emissions Durability: Verification that vehicles maintain established emission levels throughout their operational lifespan.
One of the most significant shifts involves the ‘Exento’ (Exempt) hologram. Under the new proposal, this status would be reserved exclusively for vehicles that produce zero tailpipe emissions, effectively excluding many internal combustion engine vehicles that currently qualify.
Addressing Air Quality Concerns
The Metropolitan Area of the Valley of Mexico currently has approximately 6.5 million registered vehicles, with about 300,000 new units added annually. With ozone contamination levels showing an upward trend in recent monitoring, authorities are under pressure to refine environmental policies. The ICM argues that many vehicles currently eligible for restricted circulation holograms may have degraded emission control systems, undermining the effectiveness of the existing verification program.
Next Steps for Implementation
It is important to note that these measures are currently in the proposal stage and are not yet in force. The CAMe must conduct a thorough review before any new regulations are approved and officially published. Until such time, motorists must continue to follow the current verification requirements.
If approved, the new criteria are expected to be implemented during the first half of 2027. Authorities have not yet set a definitive date for the potential changes, and current rules remain fully operational for all drivers in the region.
