It balances of greenhouse gas emission were to be draw up, it would allow the relative contributions of various sectors to be evaluated in their respective countries and, taking their impact on the global environment and socio-economic development into account, enable the necessary corrective measures to be defined. In terms of the direct warming potential of certain gazes alone, the contributions of land clearing, in Senegal and Ivory Coast respectively, reach 50 and 66% of the overall emissions, those of biomass converted into energy 20 and 23%, while those due to the use of fossil fuel reach only 14 and 5%. When the admittedly hard to quantify indirect effects are taken into account, the contribution of bush fires is no langer negligible : 22 and 14% for these same two countries. The total contribution per capita is thus 4.5 TE CO 2 (tonne equivalents of CO 2) in Senegal, 7.5 in the Ivory Coast as against over 8 in Brazil, 16.5 in France and 28 in the United States.
