Abstract: This paper deals with the risk of global warming as intensified by the carbon dioxide (CO2) emissions of the transport sector, particularly in gasoline-powered vehicles in Brazil. Car ownership and use are increasing rapidly partly because of very poor public transport quality, which, in turn, is causing higher emission levels of CO2. In this connection, the use of ethanol in Brazil for the transport sector may prove to be an important alternative, furthering the efforts to stabilise the actual level of gases in the atmosphere. The energy derived from biomass, and in this case, from a renewable, ||clean|| source, i.e., from sugar-cane, has the unquestionable advantage of permitting the almost complete reabsorption of CO2 emitted through the combustion of fuel alcohol. This closed cycle allows, in principle, the increase of the energy supply, essential for economic development, with fewer hazards to the environment.
Keywords: global warming; air pollution; ethanol; transport.
