Sustainable performance assessment of public–private partnership infrastructure projects in Ghana

Purpose Ghana is increasingly making use of public–private partnership (PPP) investments in infrastructure projects. There are 30 national projects and numerous contracts at the local government level under the PPP contracts with the goal of using PPPs to address the country’s huge infrastructure gap by 2030. However, there is an assessment gap on the projects meeting the sustainable development goals because there are no established sustainable performance measures for the projects. Therefore, this study aims at identifying and analysing the key sustainable performance measures for PPP infrastructure projects in Ghana. Design/methodology/approach The research approach in this study follows three steps of literature review, collection of questionnaire data from 249 PPP practitioners and fuzzy synthetic analysis of the data. Findings The results indicate climate resilience, inclusive and cultural diversity, least carbon emissions and adequate collection of revenue as the key sustainable performance of PPP infrastructures in Ghana. Research limitations/implications This article is useful for local (within Ghana) and international research into sustainable assessment of PPP projects. Practical implications The findings will guide the development of socially inclusive, environmentally conscious and sound governance performance assessment policies and practices to deliver PPP projects. Originality/value The study should be valuable for PPP practitioners to effectively assess sustainable development goals in the outcomes of PPP projects.
