Campaign to Measure Vehicular Emissions in Ciudad Juarez

CAMPAIGN TO MEASURE VEHICULAR EMISSIONS IN CIUDAD JUAREZ

2006

Abstract

The present study conducted an environmental impact assessment on the results of importing used vehicles into Ciudad Juarez, Chihuahua. We found that in comparison to the average emissions emitted by private cars in Mexico City, the vehicles that come from the United States to this border city have higher emission levels of nitrogen oxide, hydrocarbons, and carbon monoxide 101, 99, and 61%, respectively. The absence of governing regulations on emissions for cars crossing the northern border limits the incorporation of cleaner technologies, and directly impacts on air quality and public health.

At the time of the study, Mexican law does not contemplate that imported used vehicles -temporarily or permanently- meet certain emission levels of pollutants when they cross the border or enter the country. Between October 2005 to May 2012 the light vehicle fleet increased by 11 million 356 thousand 790 units, 43% of which was comprised of imported used units and 57% of new cars sold in the country.
