Examining the implantation of sustainability into state procurement decision models: An experiential overview of the Nigerian public sector

Green Public Procurement (GPP) is a public policy tool that facilitates the embedding of the Triple Bottom Line (TBL) goals of sustainable development. Several research studies have examined the embedding of sustainability into state procurement decisions; however, in the main, empirical studies on the incorporation of sustainability into public procurement processes, frameworks and decision-making in Sub-Saharan Africa (SSA) countries have been overlooked. Using data gathered from a questionnaire survey, this paper aims to examine the embedding of sustainability into public procurement decisions in Nigeria. Specifically, the research measures the impact of procurement policy, lifecycle analysis (LCA), procurement processes and supplier relationships in the implanting of sustainability in public procurement. Results were obtained from a questionnaire sent to 103 respondents working in procurement departments in the Nigerian public sector. 58 responses were returned representing a 57% response rate. The findings show that, cumulatively, there are inadequate policy measures to address the TBL of sustainability. The research outcomes also show that supplier relationships are not optimized and LCA is not sufficiently utilised in the public procurement decision making process in Nigeria. In terms of policy, the study will enable governments in developing countries to formulate and implement effective GPP policies.
