Level of awareness and knowledge of procurement practitioners on green public procurement: a systematic review

Purpose - Green public procurement (GPP) is critical to achieving sustainable development goal 12, which focuses on sustainable consumption and production. However, GPP adoption is fragmented, suggesting the need to raise awareness and knowledge. This study aims to systematically review the literature on the level of awareness and knowledge of procurement practitioners (PPs) on GPP. The objectives are to assess PPs’ awareness and knowledge of GPP and identify the factors that enhance their awareness and knowledge. Design/methodology/approach - The study used the preferred reporting items for systematic reviews and meta-analysis protocol. Thirteen papers were retrieved from Scopus, Web of Science, Wiley Online Library and Google Scholar databases. The papers were thematically analysed for discussion. Findings - The study shows that PPs’ educational level, working experience and statutory regulations positively affected their knowledge of GPP. Also, training programmes, technological know-how, statutory regulations, performance monitoring and evaluation, transformational leadership by top management and employees joining professional groups enhance PPs’ awareness and knowledge in public institutions. Research limitations/implications - This study is a systematic review that does not contain original empirical data to support its findings. Practical implications - This study encourages investment in education and training to enhance GPP performance. Findings should guide managers in improving GPP knowledge through employees’ enhanced working experience and educational status. Employees’ awareness and knowledge levels will improve by joining professional bodies, training programmes and transformational leadership. Findings should help suppliers to improve their green knowledge to keep up with changes in the public sector. Social implications - Awareness and knowledge of PPs increase green consumption and production, creating a cleaner environment. Originality/value - This research improves understanding of how awareness and knowledge of PPs enhance GPP performance. The study identifies areas managers should prioritise to increase employees’ awareness and knowledge of GPP for improved performance.
