Abstract

The domestic and industrial gaseous emissions are estimated in order to complete the high resolution inventory of biogenic and pyrogenic emissions performed over the Côte d’Ivoire (Ivory Coast). In this study, domestic emissions are estimated from the regional population density including rural or urban character, the amount of fuel (wood and charcoal) used per cape per year and emission factors. The population density and the amount of fuel are two key parameters that make up the regional emissivity (0.0081 to 0.0685 kg/m² per year), which discriminates the nineteen regions of Côte d’Ivoire into seven groups. Domestic emissions range from 0.016 to 0.1 g/m² per year for NO_x, 3.9 to 33 g/m² per year for CO and 35.2 to 297 g/m² per year for CO₂. Regions with high domestic emissions are located in forest areas and are both producers and consumers of charcoal. Côte d’Ivoire emits 1.6 × 10⁷ kg per year of NO_x domestic, 3.8 × 10⁹ kg of CO and nine times more CO₂. All these results are consistent with the Emission Database for Global Atmospheric Research (EDGAR). Industrial emissions are not calculated but taken from the EDGAR database to produce a distribution map. These emissions come from the release of major industries (Abidjan, Bouaké and San Pedro) and the manufacture of charcoal. The maximum of industrial emissions is around Abidjan with 10⁷ kg per year for CO and 10⁶ kg per year for NO_x.
