A simple procedure is proposed in order to develop an inventory of emissions with high resolution (9 km) for the transport sector based on a geographic information system using readily available information. The basic variable used is the vehicle activity (vehicle - km transported) estimated from fuel consumption and fuel efficiency. This information is distributed to a spatial grid according to a road hierarchy and segment length assigned to each street within the cell. Information on fuel is obtained from district consumption, but weighted using the DMSP-OLS Earth at night satellite image, to allow an urban scale distribution. Comparison with internatio- nal databases showed a better spatial distribution of greenhouse gases (GHG) emissions in the transport sector, but similar total national values.
