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.
