All 14 districts in Ghana’s Western Region are set to take part in the Independent Review Process (IRP) under the Infrastructure Transparency Initiative (CoST), marking a significant scale-up of efforts to strengthen transparency and accountability in public infrastructure delivery at the sub-national level. The IRP (also referred to as the assurance process) involves systematically reviewing disclosed infrastructure data to assess completeness, accuracy, and compliance with legal and procedural requirements; this builds on earlier pilot assurance activities and expands them to cover all local government jurisdictions in the region. Stakeholders from district assemblies and civil society are being oriented on the IRP methodology, implementation plans, and timelines as part of the rollout, with emphasis on enhancing citizen participation, value for money, and governance in infrastructure projects. Government and technical partners have underscored the importance of rigorous independent review work to ensure truthful disclosures, enable oversight, and foster public trust, while broader efforts continue to align CoST processes with broader national infrastructure transparency goals.
