How to advance the adoption of Sustainable Public Procurement (SPP)? This issue is not fully apprehended yet. This bibliometric analysis investigates the variables related to SPP adoption from the Change Management (CM) and Change Readiness (CR) perspective, correspondingly mapping the research themes emerging in this topic. The source articles search used a Systematic Literature Review (SLR) protocol referring to the PRISMA 2020 statement. We explore paper articles in the databases of Emerald, SAGE, Science Direct, Springer, Taylor & Francis, Wiley, MDPI, IOPscience, and ProQuest. Then We conducted clustering and in-depth analysis of co-occurrence keywords and terms used in the manuscript reviewed for mapping research themes and variables related to CM and CR to adopt SPP. The contribution of this review shows research themes that are currently emerging researched on the topic of CM and CR for the adoption of SPP based on the time distribution of each research themes cluster.
