Green public procurement in construction: A systematic review

Abstract

Green Public Procurement (GPP) is an increasingly important environmental policy being incorporated with national action plans (NAP) across the European Union (EU). The aim of this paper is to look at related literature in the construction industry with a goal of identifying any gaps in literature. In addition, the review defines different facilitator and barriers to implementing GPP in the construction field. The paper employs a relatively unique approach using a theoretical framework to explore a wider set of variables within the GPP field. All papers from year 2000 onwards in English were considered for the review. The review finds a lack of emphasis on systems modelling within the reviewed paper set and a need for more diverse economic evaluation metrics that incorporate social and environmental costs. Furthermore, the paper discusses broad range of subjects varying from behaviour to tendering procedure, highlighting potential avenues of future research.
