Sustainable Public Procurement: The Impact of Ability, Motivation, and Opportunity on the Implementation of Different Types of Sustainable Public Procurement

Public organisations develop sustainable public procurement (SPP) policies to compel suppliers to contribute to societal goals. Studies show that the ability, motivation, and opportunity that procurers have to procure in a sustainable manner affect the uptake of SPP. Most studies into SPP examine these factors only in the context of one type of SPP (e.g., green procurement). The goal of this paper is therefore to examine the relationship between ability, motivation, and opportunity and six types of SPP: (1) green public procurement, (2) social return on investment, (3) circular economy, (4) bio-based public procurement, (5) innovation-oriented public procurement and (6) international social criteria. An online survey was administered amongst procurers working in Dutch public organisations. The research shows that ability, motivation, and opportunity affect Green Public Procurement (GPP). Opportunity did affect green public procurement, innovation-oriented public procurement and circular economy, but not the other types of SPP. We were unable to identify an antecedent of more social types of SPP in this research. This research shows that findings based on GPP cannot be directly generalized to other types of SPP, and that there is a need for research into the antecedents of social types of SPP.
