The extensive use of solid fuels in food preparation such as firewood and charcoal presents problems for the environment, human health, and the economy. In Nigeria, more than 175 million people rely on traditional biomass for daily cooking. While significant research has been done on access to clean cooking fuels among households, particularly households in rural areas, there is a gap in the study of access to clean fuels among food vendors in developing countries, including Nigeria. This study explores factors influencing access to clean cooking fuel among food vendors in Nigeria. The study adopts a cross-sectional survey design, a pretested questionnaire was administered to all the registered food vendors in the study area. The results show that a significant number of the food vendors in the study area use solid fuels such as firewood and coal. Probit regression result indicates that education and income are significant factors that increase predicted probability of the use of clean fuel among food vendors. Empirical findings also show that financial constraints, availability and distribution of clean fuel, technical issues, and lack of information on the importance of clean fuel usage are some of the attention-seeking challenges inhibiting the adoption of clean cooking fuels among food vendors. Thus, the study suggests the need for integrated strategies that aim at increasing awareness of the benefits of adopting clean cooking fuels among food vendors, improving the affordability of clean cooking fuels, and providing technical assistance for transitioning into clean cooking fuels.
