Currently, urban buses represent less than 1% of the vehicle fleet in the São Paulo metropolitan region, but account for 21% of vehicle emissions, mainly due to the use of diesel as a fuel. In combustion transport, it assumes the predominant role in the daily displacement of the population, accounting for a large part of pollutant emissions from large urban centers. Thus, the objective of this work is to analyze governmental strategies for the gradual reduction in pollutant emissions in urban public transport in the metropolitan region of São Paulo. One of the alternatives for the decarburization of the urban public transport sector focuses on a combination of technologies and alternative fuels. Ethanol, hydrogen, electric and natural gas are the fuels in question most rated for this replacement, each with its specificities, advantages and disadvantages. Thus, aiming at a low carbon economy in the transport sector in the state of São Paulo, this study focuses on promoting efficiency measures, improvements in public transport infrastructure and technological challenges, environmental impacts, and climate change policies. With the use of these fuels, considered alternative, it is planned to reduce greenhouse gases, mainly CO2, in urban public transport.
