Abstract
This study examined the relationship between e-procurement practices and environmental sustainability at Kampala Capital City Authority (KCCA), Uganda. Specifically, the study assessed the effects of mandatory environmental criteria in e-procurement templates, e-procurement contract management, and supplier compliance monitoring on environmental sustainability outcomes. Anchored in Institutional Theory, the research adopted a quantitative case study design, using a structured questionnaire administered to 80 selected respondents, of whom 57 provided usable responses. Data were analyzed using descriptive statistics, Pearson correlation, and multiple regression analysis with the aid of SPSS.
The results obtained showed that e-procurement practices have a positive relationship with the outcomes of environmental sustainability. Correlation results revealed that among all the three dimensions of e-procurement and sustainability outcomes were strongly correlated and had significant relationships. The regression analysis further revealed that supplier compliance monitoring had the greatest and statistically significant impact on environmental sustainability, with mandatory environmental criteria and contract management showing positive but also marginally significant impacts. In general, the model had a high predictive ability, with 68.2% of the variation in the level of environmental sustainability explained. The research finds that although KCCA has achieved significant progress towards embedding environmental concern into e-procurement, more can be done in terms of enhancing supplier compliance monitoring efforts to achieve more significant sustainability results. The research suggests to strengthen the enforcement mechanisms, to enhance the digital monitoring system, and to develop the capacity of the procurement employees and suppliers. The results are useful both in policy and practice because they provide empirical evidence of how the use of e-procurement can be exploited to promote environmental sustainability in public sector procurement in Uganda.
