Over the last few decades, discussions on addressing climate challenges have unfolded even as we experience their effects. Although cars and motorcycles are the primary emitters of pollutants, buses also play a significant role in greenhouse gas emissions and the rise of illnesses related to air pollution. In this regard, adopting new technologies, such as electric buses and alternative fuels, is essential to reducing their impact on public health and the environment.
According to MobiliDADOS, public transit accounts for 40% of trips taken in Brazilian metropolitan areas, with buses being the most widely used mode of transportation. The use of fossil-fuel-powered engines in bus fleets is the primary driver of increased air pollution-related illnesses, as the size of the particulate matter emitted during combustion makes them more dangerous than those from private motorized vehicles. According to the World Health Organization, air pollution was the leading cause of death in the country in 2016.
