ABSTRACT We describe the EMITEMA-EIM atmospheric emission model, and how it has been used along with CORINAIR emission factors to estimate the annual emissions in the Barcelona area in 1990. The study area is a 39 x 39 km2 square with a high population density and important industrial activities. The space and time resolution of the emissions is, respectively, 1 km2 and 1 h. The pollutants considered were NOx, CO, SO2, particles, methane and several VOCs (alkanes, alkenes, aromatics and aldehydes). The emission sources studied were road traffic, air traffic, industrial activities, gas stations, domestic heating and biogenic emission from forests. Methodologies for each of these sources are described in this paper. Finally, we present and analyse the results.

    ABSTRACT: A vehicle emission model has been developed in order to estimate spatially desegregated emissions (highway, roads and streets) from road traffic using the ARC/INFO geographic information system (GIS), with a spatial resolution for each cell of 1x1 km 2 , and a temporal time-scales for the calculation of emissions on an annual, monthly, daily and hourly basis.. The model takes into account the hot, cold and evaporative emissions and uses CORINAIR's emission factors. It considers the following pollutants: CO, NO x (NO and NO 2), SO 2 , particles and several VOC. This model has been applied to obtain the emission inventory for Catalonia (Spain) for year 1994 from this source. The total amount of pollutants emitted is 407,309 tones/year: 69.6% of total emissions correspond to CO, 19.11% to NO x , 8.61% to VOC's, 1.65% to SO 2 and 1.03% to TSP.

    ABSTRACT: Emissions of greenhouse gases for the City of Barcelona are estimated for the period 1987-1994. The sources considered are: public and private transportation; industrial, commercial and domestic activities; and municipal solid waste disposal. The results show that the main source of CO2 emissions in Barcelona is private vehicle transportation, which accounts, as an average for the period studied, for 35% of total emissions. The second most important source is the municipal solid waste landfill facility of the city (24% of total emissions). The percentages for the remaining sources under consideration were: 14% electricity, 12% natural gas, 5% incineration, and 3% liquefied petroleum gases. However, the values for CO2 emissions per inhabitant over the period studied are lower than those for any other industrialized city available for comparison. This is closely related to the high percentage of electricity generation from nuclear power stations and hydro power facilities, and also to the extensive use of natural gas for domestic uses.
