Buenos Aires	Traffic emissions using EDGAR database; Concentrations from WHO database:No data available for Buenos Aires. For now, we are using Cordoba city’s estimate – 32% in 2010. Source: WHO source apportionment database. Since, Buenos Aires is coastal and Cordoba is not, there could be some bias in this number.

Santiago	Traffic emissions using EDGAR database; Concentrations from WHO database		V:\Studies\MOVED\HealthImpact\Data\TIGTHAT\global transport source apportionment ; http://apps.who.int/gho/data/view.main.AMBIENTCITY2016?lang=en		ITHIM-R\code\processing traffic emissions	EDGAR estimates of transport emission shares across the modes do not seem correct. It reports 4% of transport emissions from passenger cars. This is similar to Brazilian cities where we know ethanol is used. But I checked Chile doesn’t have that. We used a non-ethanol city such as Bogota to estimate. Transport emission estimates for Mexico City and Santiago using Bogota: Using travel surveys, calculated the distance travelled (in relative terms also works) by ‘road-based’ motorised modes but excluding LDV and HDV as these are not included in the travel surveys. The distance calculated corresponds to the city population and not just the sample. Using this distance, we calculate emissions per km for each mode, and then estimate emissions for other cities using the corresponding distance travelled by each mode. Once the emissions for different modes are calculated (for LDV and HDV emissions are same as reported in EDGAR database), we calculate the percent contributions by each mode. Corrected emission shares: Buses (0.0728), heavy duty vehicles (0.0263), light duty vehicles (0.187), motorcycles (0.00565), passenger cars (0.708) Two estimates in Santiago city transport emission shares—one corrected and one using EDGAR
