THE USE OF BIODIESEL TO REDUCE CO2 EMISSIONS CAUSED BY THE URBAN BUS FLEET OF RIO DE JANEIRO

For several years, the use of oil to move vehicles, transport people, generate energy and other activities necessary for social life, has made the world very dependent on this input. Among the alternative fuels studied, we have the biodiesel, a fuel obtained through the transesterification process of vegetable oils or animal fats, which has become a potential substitute for petroleum diesel. Among the advantages of using this fuel, the following stand out: being renewable, reducing the country’s dependence on oil, and having lower rates of greenhouse gas emissions than petro diesel. Among those gases stands out the CO2, which contributes to the global warming and will be the target of this study. Based on the calculations made taking into account the consumption of petro diesel in Rio de Janeiro, it is intended to quantify the emissions from its use up to 2030 in the fleet of urban buses of the city of Rio de Janeiro and, in parallel, calculate the potential to reduce emissions with the use of biodiesel in the percentages established by the Brazilian Government in the same period.
