This research presents the design of a system for air quality managing: case Cali - Colombia. This structure facilitates to the interested parts to establish policies of emission and unmission of atmospheric pollutants of mobile and stationary sources, to define the environmental and sanitary priorities and to adopt the strategies to reduce his spoilage. It was used concepts of environmental management were in use as the evaluation of the environmental risk for identifying the emission sources, for evaluating the level of emission and concentration of atmospheric pollutants, for
