This research investigated how the National e-Procurement System contributes to sustainable public procurement by analyzing its contribution to sustainable public procurement through four dimensions: reduction of paperwork, carbon emissions reduction, cartridge reduction, and reduction of transportation and communication cost for procuring organizations and suppliers. The study is guided by the natural-resource-based view, transaction cost economics, and the technology-organization-environment framework. An empirical desktop-review design was employed. Data was deliberately selected from Tanzanian laws; Public Procurement Regulatory Authority reports and guidelines; the National e-Procurement System sources; the 2025 Methodology for Assessing Procurement Systems report; and precisely 20 peer-reviewed journal articles published between 2024 and 2026. Thematic analysis was employed to analyze the data. The findings reveal that e-tendering, bidding, evaluation, approval, contract management, and communication minimize the use of paper, copy, bind, and storage processes. Also, the National e-Procurement System saved 617.85 tons of carbon dioxide emissions in one year. Moreover, Tanzania’s National e-Procurement System also eliminates the need for travel on behalf of both the suppliers and the purchasing organization, as well as officers of the purchasing organization. In this way, costs of fuel, fare, accommodation, courier services, and opportunity costs are reduced along with expanding geographical reach for tender documents. The study recommends that Public Procurement Regulatory Authority should integrate a sustainability dashboard into Tanzania’s National e-Procurement System to monitor resource savings and independently verify avoided carbon dioxide emissions. Also, Tanzania’s National e-Procurement System should promote environmentally friendly supplies while the government improves connectivity, training and support to prevent supplier exclusion.

Public procurement performance is critical to the public sector due to the substantial public funds spent on acquiring goods, works, and services. The study aimed to examine the moderating effect of political interference on staff competency toward the achievement of procurement performance in parastatal organizations in Tanzania. Grounded on the stakeholder and the resource-based view theories, the study adopted the explanatory research design. A structured questionnaire was used to collect data from heads of departments from 93 state-owned organizations in the Dar es Salaam Region. A sample of 256 respondents was randomly selected using the Yamane formula from a population of 712 heads of departments. Data were analyzed using SPSS and the PROCESS macro (Model 1) to examine whether political interference moderates the relationship between procurement staff competence and procurement performance. The findings revealed that staff competence has a positive influence on the performance of the procurement function within the organization. On the other hand, the study found that political interference in the procurement process, particularly during the tendering stage and contract implementation, negatively affects procurement performance. However, the results further indicated that political interference does not significantly moderate the relationship between staff competence and procurement performance. The study concluded that improved procurement performance within the organization is largely attributable to competent staff, whereas political interference contributes to poor procurement performance. The study recommends that organizational management should invest in enhancing staff competence, particularly through training, certification, clear career paths, and competence management systems in order to improve procurement performance, and should ensure that the procurement function is protected from political interference; as such interference has a detrimental effect on procurement processes.
