RESUMO

This study presents an analysis of the levels of vehicles emissions related to the pollution problems in São Paulo City. Using a methodology called bottom-up, this thesis presents a theoretical evaluation on the rates of pollutants coming out the exhaust pipe of the largest light vehicles fleet in Brazil. Issues related to daily city activities such as the fleet growth, fuels, public transportation, air pollution and its effects on the population health and the atmospheric influence in the region as well are presented. Simulations for scenarios drawn were based on a simple but efficient, implementation of bottom-up approach that employs, for calculations, the emission factors according to the changing phases of PROCONVE (the Brazilian National Program for the Pollution Control of Vehicles) for the amount of pollutants emitted per year. The scenarios consider that replacement of older vehicles by new ones is positive for the environment. Some scenarios may be considered as non-conservative alternatives and others can be seen as conservative, but all demonstrate significant improvements to the quality of air in São Paulo City. The evolution of the phases mentioned have brought many benefits to the environment through new technologies developed for new vehicles and represent a solution for the future, when improvements in atmospheric conditions must be met. Issues such as public policies and laws specific to the replacement of old vehicles still have to be improved. In practical means, the traffic is increasingly chaotic, in part by the amount of cars in poor use that still run and break every day, directly affecting the air quality in metropolitan region.
