Environmental and economic accounting for biomass energy in Ethiopia.

Background: Energy consumption is inextricably linked with the economy and the environment. The interlinkages are particularly important in low-income countries such as Ethiopia where biomass fuels account for more than 85% of the total energy consumed. This paper aims to assess the energy and economic values, and environmental emissions of solid biomass fuels in Ethiopia. Methods: The study considered four common solid biomass fuels (firewood, charcoal, crop residues, and cattle dung) in Ethiopia. The amount of biomass fuels during the Ethiopian fiscal year 2015/2016 was compiled from various data sources. Prices, net calorific values, and emission factors per mass of fuels were then used to calculate the economic, energy, and emission values of the solid biomass fuels. Results: The study showed that, in 2015/2016, the consumption of the four solid biomass fuels contributed between 33,327 and 44,547 ktoe to the total energy consumption with an estimated economic value of 4.4–7.7% of the GDP at current market prices. The stationary combustion of the biomass fuels could result in 165–219 Mt of CO₂eq emissions, whereas the fuelwood consumption could potentially impinge on the size or quality of 730 thousand ha of forest, woodlands, and shrublands. Conclusions: The results suggest that the country should scale-up its policy measures aimed at increasing households' access to modern energy sources and energy-efficient cooking stoves while at the same time strengthening its afforestation and reforestation activities.
