Comprehensive Assessment of the Vehicle Inspection Program in the Metropolitan Area of the Valley of Mexico -2010
The Mandatory Vehicle Inspection Program (PVVO acronym in Spanish) has the purpose of controlling exhaust emissions from the main source of air pollution in the Valley of Mexico, so its proper operation is vital to ensuring good air quality in the country’s most populated metropolitan area. In response to citizens’ concerns about the efficiency and usefulness of this program, in this comprehensive assessment we present a performance diagnosis of verification/inspection centers (“vericentros”), with the purpose of providing the Metropolitan Environment Commission and the governments of Mexico City and the State of Mexico a set of technical elements that will allow them to develop strategies and immediate actions for improvement. It is important to point out that this study was carried out in 2010, prior to the installation of GDF-2009 equipment which replaced the CAM-97.
In general, Verification Centers in the Metropolitan Area of the Valley of Mexico (ZMVM acronym in Spanish) presented technological obsolescence and 42% of them did not comply with current environmental regulations. However, the direct benefits of the program – proven and estimated in lab testing and measurement campaigns of vehicle emissions with remote sensors – imply reducing 340,000 tons of carbon monoxide and 5,000 tons of volatile organic compounds. To this benefit, derived from stimulus to tune up vehicles before taking them to verification centers, we should also add the renewal of vehicle induced by the “Hoy No Circula” program and detection campaigns of visibly polluting vehicles; a circumstance that has caused the vehicular fleet in the Valley of Mexico to be the most technologically advanced and best maintained in the country.
