Emissions generated by the transportation sector continue to be one of the main causes of air pollution in Latin American cities. Despite major technological improvements in the automotive industry, motor vehicles continue to rely primarily on fossil fuels. Electromobility is emerging as a potential solution for the transport of the future, but there are still several decades of transition, during which conventional engines will coexist with zero-emission vehicles. Emission inventories from mobile sources must be able to incorporate these changes, with high-resolution spatial disaggregation, offering emissions of local and global pollutants, on urban and national scales. This paper presents results of three studies, where emission inventory estimation methodologies are combined with local information on activity and emission factors, as well as projections of new technologies and forms of mobility that seek to achieve carbon neutrality by the year 2050. A bottom-up, high-resolution national inventory of exhaust emissions for on-road transportation is presented for Chile, covering the period 1990-2020. Recent advances are also shown in the measurement of local emission factors, using portable emission measurement systems, as well as real-time vehicle counts with specialized algorithms and low-cost equipment. Finally, preliminary results of a forecast analysis for the years 2020-2050 are presented, which considers various official strategies for all modes of transport in Chile, with the aim of evaluating the feasibility of achieving carbon neutrality by 2050, while reducing emissions of criteria pollutants in urban areas.
