Abstract: Worldwide, Brazil is the seventh largest contributor to greenhouse gases emissions. Public transport, which is highly dependent on fossil fuels, accounts for 17% of all emissions from the Brazilian energy sector. This paper aims to identify the carbon dioxide emissions reduction potential by switching Curitiba's public transport bus fleet from diesel fueled buses to electric buses. The calculation, which was based on data collected from the system management company and from the literature, was applied into three scenarios. In the first, we estimate the system's CO2 emission for the current fuel choice, diesel; in the second, we consider the adoption of electric buses, by meeting the energy demand with the national energy matrix; and in the third, the demand would be fed by photovoltaic systems. The results indicated a CO2 emission reduction potential of about 81%, 90% and 93%, considering three different analysis: (1) buses energy demand supplied by the national electric matrix in a context of a rainfall worst-case; (2) buses energy demand supplied by the national electric matrix in a context of a rainfall best-case; and (3) energy demand supplied by solar energy. It would represent a reduction of, respectively, 68, 75 or 78 thousand tons of carbon dioxide emitted into the atmosphere per year. The results suggest that a switch from fossil fuel run buses to electric buses has a great potential to contribute to decarbonising transport, especially in cities with a large bus fleet and distance traveled.
