[Introduction]: Mobile sources, both globally and nationally, play a critical role in generating black carbon emissions, a short-lived climate forcer that has a major impact on the climate. [Objective]: Solutions are proposed that allow the mitigation of black carbon emissions generated by the transport sector within a framework of economic and technical viability. [Methodology]: The emissions generated by mobile sources were modeled, taking as the base year 2016, for which Copert 5.2 software was used. Subsequently, scenarios of reduction opportunities were established, which were evaluated taking into account their potential for decline, concordance with public policies and the cost of technology. [Results]: Mobile sources emitted 471.9 tons of black carbon into the atmosphere during 2016, equating to 217 031.7 and 707 712.2 tons of CO2e (taking as global warming potential 460 and 1500, respectively). It is proposed to: the use of low-emission fuels, the incorporation of electric vehicles and technological improvements in the engine system to reduce exhaust emissions. [Conclusions]: The most feasible emission mitigation measures are those related to the incorporation of low-emission fuels, such as biodiesel and low sulphur diesel. It is vitally important to include concrete actions for the reduction of black carbon emissions within national climate change policies, as the reduction of these has positive short-term impacts.
