This study examines the socioeconomic impact of the ban on single-use plastics (SUPs) in Lagos State, Nigeria, with particular attention to households, small businesses, and informal sector workers. The research explores how the ban has affected economic activities, behavioural adaptation, and environmental conditions across the state. A mixed-methods approach was employed, combining quantitative data from questionnaires distributed to traders, households, and micro and small enterprises across selected local government areas with qualitative insights from interviews conducted with officials of the Lagos State Ministry of the Environment, LAWMA, and market leaders. Grounded in the Theory of Planned Behaviour, Just Transition Theory, and the Environmental Kuznets Curve, the study analyses the relationship between behavioural change, economic transition, and environmental sustainability. The findings are expected to reveal both environmental gains—such as improved sanitation and reduced pollution—and economic challenges for low-income groups, offering valuable guidance for a more inclusive and sustainable
transition away from single-use plastics in Lagos State.
