| Sumario: | To work sustainability issues in the urban environment is one of the great challenges in current. One of the ways to reach goals of this size is through the insertion of sustainable technologies in the public transportation sector. Examples include the use of biofuel instead of fossil fuels and the adoption of hybrid electric buses. Such replacements have been carried out in the collective transportation of the city of Curitiba, Paraná, which has been a pioneer in this type of management and has 1.7 vehicles per inhabitant. Therefore, the proposal of the article is to question the extent to which these actions contribute to the sustainability of the planet. For this purpose, emissions from the vehicles that compose the city's bus fleet were quantified over a one-year period, with evaluation of opacity tests and greenhouse gas emissions [GHG's]. In the period, the public transport sector was responsible for the emission of approximately 200,000 metric tons CO2 eq. The use of biodiesel in public transportation in Curitiba prevented the emission of approximately 10,000 metric tons of CO2. The results of the opacity tests indicated that the hybrid model operating the B100 emits about 93% less black smoke. It was verified that there is a significant contribution by the city to reduce the emission of GHG's. By economic analysis, if the entire fleet of the city of Curitiba were hybrid, with the total volume of fuel used, an economy of R $ 62,558,868.08 would be obtained, which would cover public health expenditures emissions from public transportation, for example, from the city of São Paulo, the most populous in South America. |
