Globally, over 3 billion people i.e. almost 40% of world population still depends on biomass fuels such as fuel wood, charcoal, Agricultural residue, dung and coal for household energy use. The biomass energy has a share of more than 30 percent of the energy consumed in Africa. However, in most Sub-Saharan African countries accounted for 90-98 percent of household energy consumption. More than 95 percent of households in Ethiopia depend on biomass as energy source. To understand the importance of efficient wood stove technologies in mitigating the greenhouse gas emission due to burning of woodfuel for household energy use, different published scientific papers were reviewed. The findings shown that combustion of solid fuels for cooking using in efficient wood stoves emits greenhouse gases which have substantial addition to climate change, even though; dissemination and sustained use of improved cook stoves have a potential in mitigating the greenhouse gas emissions due to burning of biomass fuels for household energy use. Furthermore, it reduces the amount of fuelwood consumption which also leads to reduce deforestation and forest degradation. Therefore, achieving dissemination and sustained use of efficient wood stoves at household level have a significant benefit in mitigating the greenhouse gas emission due to burning of fuelwood for household energy use.
