Strengthening the Polluter Pays Principle in Ghana: governance reforms for ecological and economic sustainability

Sustainable natural resource governance in developing countries often falters due to weak institutional frameworks, limited enforcement capacity, and fragmented accountability mechanisms. In Ghana, the Polluter Pays Principle (PPP), which was designed to ensure that environmental degradation costs are borne by polluters, is fraught with challenges due to weak enforcement in key sectors—mining, oil, and waste management. This study critically evaluates the institutional and operational barriers to effective PPP enforcement in Ghana. Drawing on a multi-level governance framework and the theory of environmental accountability, the research integrates policy analysis, institutional mapping, and stakeholder interviews across key regulatory bodies. The study assesses institutional coordination, financial accountability, and transparency mechanisms influencing PPP implementation. It further explores the socio-environmental consequences of ineffective enforcement in the context of illegal mining (galamsey) and industrial pollution. The findings revealed that PPP enforcement in Ghana remains fragmented and uneven across sectors, primarily due to overlapping mandates among regulatory bodies and poor coordination among agencies such as the Environmental Protection Agency and the Minerals Commission, resulting in limited accountability and transparency. However, multi-level governance reforms via key innovations such as harmonising institutional roles, strengthening financial accountability, and integrating digital tools for transparency lead to effective PPP enforcement. Ultimately, the study positions PPP not only as an environmental policy tool but also as a robust governance mechanism capable of balancing ecological protection with inclusive economic growth to advance Ghana’s sustainable resource management and contribute significantly to achieving the Sustainable Development Goals (SDGs).
