Fuel-based lighting is generally of low quality and expensive and the same is true for Nigeria households that are heavily dependent on kerosene. Even though the Nigerian government spends millions of dollars annually on its kerosene subsidy, because of a data deficiency, not much is known about the kerosene situation in Nigeria. The Power for All Nigeria campaign along with the United Nation Environment Program (UNEP) want to support Nigeria in phasing out kerosene lamps and to promote a market transition to off-grid and energy- efficient lighting products. To do so, Power for All and UNEP engaged in a project that included country-specific kerosene market assessments, policy formulation, advocacy and market participation. As part of the project, Power for All conducted a study on the state of kerosene lighting in Nigeria, including the financial costs, health and safety risks of kerosene use, environmental impacts of kerosene use and the benefits of transition to solar lighting.
