The most important environmentalbenefit of the day is the reduction of pollutants associated with private cars shall also be expected in the reduction of PM with the great reduction of ACPM-diesel.

Duringthe day is expected to decrease in the concentration levels of major pollutants in O3 and CO besides reducing noise in lighter traffic infrastructure.

And at the end of the daythere will be a consolidated report of the pollutants analyzed.

Analysis and results of the pollutants in the last five years in Bogota on the day of no car.

Theconcentration of particulate material from previous years making a comparison has a great tendency to decrease in concentration as shown in the graph

Has improved air quality byimproving the quality of diesel fuel also delivered by Ecopetrol.

The average of the particular material is influenced by the 2007 wildfires that occurred in early 2010 and 2011.Ozone and behavior analysis of Car Free Day.

for Car Free Day in the early years of this initiative was only reported O3 mainly in parks and increasing its coverage in2010 and early 2011.
