In construction industry, sustainability is no longer an option but an imperative. It turns to be an essential element for project stakeholders. Although green procurement is an environmental policy instrument that considers the impact of procurement and purchasing process for the sustainability of project development. However, the concept in Malaysia is still in its early stages and encounters barriers to make a paradigm shift towards a greener approach. This paper tends to shed light on the key success factors and to develop a roadmap for implementing green procurement in building and infrastructure projects. This could pave the road for establishing a transformation plan that could gradually overcome the current challenges. In this study, 380 Malaysian corporations were surveyed to determine their perspective on 50 factors affecting procurement delivery. A number of 142 questionnaires were assessed as valid responses. Results revealed that there is an excellent consistency in the investigated factors which have been statistically analyzed. The significant factors can be categorized into themes namely, perception, organizational management, regulative, logistical, contractual, technical, strategic and financial factors. © 2020 IOP Publishing Ltd.
