The study evaluates the effectiveness of Nigeria’s regulatory frameworks in fostering multi-stakeholder engagement for sustainable public procurement practices. Although Nigeria’s Public Procurement Act was implemented in 2007 to create a framework for efficiency and transparency, there remains an issue of the operationalisation of the standards for environmental, social and economic sustainability, as well as effective stakeholder engagement. The data were collected from 341 purposely chosen stakeholders from public, private and civil society organizations (CSOs) and local communities from twelve organizations and communities using a quantitative approach and a descriptive survey design. The data indicates minimal systemic coordination between all stakeholders (Mean=2.77), while local communities’ participation and public policy impacts procurement results the most. According to the results of the study, high costs of green alternatives (mean = 4.04) (institutional resistance to change (mean = 3.74) and weak enforcement of existing regulations (mean = 3.40) are important barriers to sustainable procurement. The study concludes that Nigeria should strengthen participatory framework for truly inclusive stakeholder engagement in policy making and implementation; provide tax incentives for the private sector; and stricter regulatory monitoring and enforcement for sustainable public procurement (Mean = 4.12). In order to promote productivity and sustainability, the legislation should be in line with the best practices.
