We used the COPERT IV model for computing annual emissions. Data collection and main criteria for the selection of activity data and emission factors are discussed in Sections 2.1 and 2.2 respectively. A quality control system consisting of routine accuracy checks on data acquisition and calculations and the use of customary procedures used in our Laboratory for archiving information was implemented. verification is dealt within Section 2.4.
The MABA was analyzed by its 25 districts and also according to four geographical zones, the city of Buenos Aires and the western, northern, and southern regions, grouping those districts that share similar socioeconomic characteristics (Fig. 1). Emissions of greenhouse gases and criteria pollutants were estimated. Our estimates of PM emissions account for exhaust and non-exhaust components.
