The smart green supply chain (SGSC) is an emerging phenomenon because of the advancement of sustainable smart business and information technology trends. Various small and large enterprises are putting all their efforts into imbibing Industry 4.0 (I4.0) based disruptive technologies to transform their green supply chain management (GSCM) to be a smart green supply chain management (SGSCM) to fetch advantages of increased efficiency that leads to financial gain. Smart green supply chain management practices (SGSCMP) involving I4.0 disruptive technologies can provide greater transparency and quick decision-making. The SGSCMP must be assessed to work for I4.0 readiness to compete the global competitions. Hence, the present research attempts to assess the SGSCM-based practices adopted by manufacturers in KSA. Various SGSCMPs have been identified by carrying out the literature review. The Analytic hierarchy process with group decision-making (AHP-GDM) is used using the expert judgment of the expert group consisting of five experts. The expert group assessed the SGSCMP for their importance and three companies adopting such SGSCMP are analyzed for their ranking.
