This work has as its purpose to evaluate the greenhouse effect gases (GHGs) emissions from ethanol-powered buses, which were introduced in the urban transportation system of the city of São Paulo, in 2007, by means of Project BEST - BioEthanol for Sustainable Transport with the goal of promoting ethanol usage in substitution to diesel in public transportation, aiming at the reduction of atmospheric pollution in great urban centers and at the reduction of global warming. The engine is advanced even for the strict European emission standards, because it meets the EURO 5 specifications and the Enhanced Environmental Vehicle (EEV), besides surpassing the limits imposed by the P-7 stage of PROCONVE. Today, ethanol-powered buses became a reality, because the chassis and the engine, then imported, as well as the additive for the ethanol, are already manufactured in Brazil.
