Furthermore, for a company, boosting economic and financial viability by utilizing sustainable component procurement partnerships might assist in the transition to a sustainable supply chain management, which includes environmentally acceptable products from green manufacturers and suppliers Furthermore, the hypothesis testing of the study helps to address the third research question, i.e., the relationship between EPTs and GPP for the sustainable supply chain management. The results of the study indicated that E-informing has a significant influence on the green procurement practices and supply chain performance in ISO 14001-certified organizations (\(\beta\) = 0.029, t-value = 0.604), in line with studies by [2; 11; 33; 40; 137; 138; 139]. The enhanced availability and accessibility of information for E-informing have contributed to greater procurement intelligence. In the case of employees/respondents of ISO 14001-certified organizations, the adoption of technology effectively leads to the free flow of communication. E-informing was found to enhance the innovation process that leads to greening the procurement process, and thus the performance of organizations [137]. The use of internet technologies such as E-informing to acquire and distribute procurement information from and to internal and external parties increases procurement transparency. Moreover, Ref. [138] concluded that E-informing had a significant impact on the intention to participate in the exchange of information across organizations and government activities regarding policies and citizenship. Similarly, E-ordering was also found to have a significant and positive effect on green procurement practices (\(\beta\) = 0.021, t-value = 0.604). Similar findings were reported by [33; 48; 67; 112; 127; 129], who asserted that the ordering of products and services through an electronic platform such as websites and frameworks leads to saving time and sustainability in the procurement process and performance. Moreover, the results are in line with the previous studies by [33; 140], which suggested that E-ordering has great importance in terms of social, economic, and environmental aspects. The hypothesis was related to E-tendering's influence on green procurement. The empirical outcomes do not provide the supporting evidence in favor of (\(\beta\) = 0.056, t-value = 0.213) the proposed hypothesis, and contradict previous research findings related to electronic tendering [33; 141; 142; 143; 144]. Previous studies clearly state that E-tendering helped in reducing costs and other administrative expenditures due to low corruption as well as less supplier complicity. Moreover, E-tendering has a higher impact on customer satisfaction and performance when implemented in organizations [145]. Further, the hypothesis was related to the influence of E-reverse auctioning on green procurement practices. The results do not provide supporting evidence in favor of (\(\beta\) = 0.019, t-value = 0.619) the proposed hypothesis, and contradict previous research findings related to electronic reverse auctioning [146; 147; 148; 149; 109]. To avoid making an erroneous purchase decision, vendors should ensure restraint in their electronic request for proposals (E-RAs), compare overall bidding activities to the corporation's business model, and make rational bid price comparisons in the closing seconds. However, [PERSON]. [148; 110] concluded that, for the construction industry, with the right principles and limits, E-RA may be used effectively to buy products, resources, and projects for building through government procurement. Finally, the last hypothesis for the study, i.e., E-sourcing, was found to have a significant impact on green procurement and performance with significant values (\(\beta\) = 0.881, t-value = 2.931). Findings by [37] stated that the E-sourcing or online sourcing platforms on the internet give such chances for SMEs to move their focus from the supply to a demand orientation, increasing their marketing pace.
