Côte d’Ivoire—Preliminary Greenhouse Gas Inventory

Abstract

The IPCC Methodology has been used to conduct a preliminary greenhouse gas emission inventory for 1990 for the energy, waste management, and agricultural sectors in Côte d’Ivoire. Emissions from the energy sector were estimated at 6.223 Tg of carbon dioxide-equivalent. Biomass burning represented almost 50% of these emissions compared with the second largest emission source, transportation, with 24%. In 1990, carbon dioxide emissions from fossil fuel burning amounted to 3,241 Gg CO2. Carbon monoxide, methane, nitrous oxide, and nitrogen oxide emissions from traditional biomass consumption were 1,119 Gg CO, 127 Gg CH4, 0.669 Gg N2O, and 4.26 Gg NOx, respectively. Charcoal, the predominant biofuel, contributed 95% of the methane, 78% of the carbon monoxide, 60% of the nitrous oxide, and 25% of nitrogen oxide emissions. By sector, residential areas are, by far, the primary biofuel emission source. Emissions from bunker fuels (to be excluded in final estimation) were 0.841 Gg CO2.Methane emissions from solid waste landfills amounted to 266 Gg CH4 in 1990. The Akouedo-Abidjan landfill contributed 63% of these emissions, with the rest coming from the other landfills in the country. Methane emissions from liquid wastes were estimated at 13.3 Gg in 1990. In the agriculture sector, emissions estimates were 311 Gg CH4, 255 Gg CO, 0.07 Gg No, and 2.46 NOx. Rice cultivation was responsible for over 80% of the CH4 emissions. Savanna burning was the main source of carbon monoxide emissions. Field burning of agricultural residues contributed most of the nitrous oxide and nitrogen oxides emissions.
