Abstract
The use of low efficient cookstoves has several severe negative impacts. Burning solid fuels
kills about 4 million people every year, a number which is higher than the combined impact
of HIV-AIDS, malaria and tuberculosis. Moreover, most of the people affected are located
in rural areas of Sub-Saharan Africa and other developing countries, where over 80% of the
population still relies on biomass as their primary source of energy, being the electricity
access only 43%. Low-efficiency cooking systems are also a major source of greenhouse
gas emissions since solid fuel cooking in Sub-Saharan Africa accounts for 1.2 and 6% of
global CO
2
and black carbon emissions, respectively. Furthermore, widespread biomass
collection by an increasing population in Sub-Saharan Africa is unsustainable, contribut-
ing to deforestation. Therefore, the impact of using traditional cooking systems is a chal-
lenge for the achievement of sustainable development targets in Sub-Saharan Africa and as
a whole globally. There are several cooking technologies used in those rural locations, but
there are no clear frameworks or polices to support sustainable cooking options, as well as
a guide for users. This paper assesses several cooking technologies with its associated fuels
and evaluated each technology in terms of energy consumption, CO
2
emissions, health
impacts and costs. It was concluded that compared with traditional wood fuel cookstoves,
electric cookstoves can reduce the energy consumption by 95.7%, CO
2
emissions by 100%
(assuming renewable carbon-free electricity) and the life cycle cost by 94%, also avoiding

concentrations per/household per year. Also, this paper indicates
that a strong and collective effort is necessary from key stakeholders to switch from tradi-
tional and unsustainable cooking technologies and fuels to cleaner and sustainable cooking
systems.
