Poor air quality in large cities such as Bogotá, due to fixed and mobile emission sources of particulate matter, negatively affects the social, economic and ecological systems of the city. Population growth is one of the main causes that influence air pollution. Therefore, it is considered necessary to analyze the cause-effect relationships of pollution, its sources and the effects on the population. For this reason, developing a model using computer tools such as system dynamics, which can evaluate different environmental policy scenarios, will help to reduce pollution levels and improve the life quality of the population. The methodology used was quasi-experimental with a quantitative approach, divided into four stages, gathering information, proposing the causal diagram, developing the simulation model and evaluating scenarios. Vensim® was the software used as the simulation tool. As a result, it was found that highly polluting stationary and mobile sources cause an uncontrolled increase in PM10. It was also found that annual conversion rates to clean technologies must be 10% per year or higher to achieve a 50% reduction in PM10 levels, in the medium and long term. The main conclusions were to determine that the use of simulation technologies such as system dynamics are very useful to formulate more effective environmental policies. The simulation presented the need for environmental policies to be long-term structural policies that do not vary depending on the change of government.
