The purpose of this paper is to evaluate the costs and benefits of interventions to reduce indoor‐air pollution arising from the use of solid biomass fuels for cooking and heating in Nigeria.

The authors use cost‐benefit analysis and assess two intervention scenarios: providing access to improved stoves; and providing access to cleaner fuels (liquefied petroleum gas – LPG – burners). Both intervention scenarios are compared with the current situation, i.e. the “business as usual” scenario where there is no attempt to reduce the present level of exposure to indoor‐air pollution from solid fuel use.

The result shows that the cost‐benefit ratio of the stove intervention is 0.388 while that of LPG is 0.371.

While providing access to cleaner fuels (LPG) has a larger health impact on the population than improved stoves, the low income level of the participants will favor the stove option because of the lower recurrent cost which is usually borne by the participants. From a public health point of view, there is need for a continued emphasis on the promotion of improved stoves to reduce exposure in households using solid fuels until everyone can have access to cleaner fuels. Furthermore, since choice of cooking technologies is influenced by income level, the intervention policy should be implemented alongside other socio‐economic development programmes.

The paper bridges the knowledge gap with respect to the indoor‐air pollution issue in Nigeria. It offers policy makers an insight into the potential net benefit of intervening to reduce indoor‐air pollution arising from the use of solid biomass fuels in Nigeria.
