Abstract: The study evaluated the impact of green procurement strategies on project sustainability in Isiolo County Government, Kenya. This study singled and checked the influence of supplier selection, supplier relationship management, monitoring and evaluation, and inventory management on sustainability of projects in the county. Informed by the Resource Based View and Lean Inventory theories, the study adopted a descriptive research design and targeted 70 procurement and project officers drawn from departments at the county level. Data was collected through structured questionnaires, where responses were analyzed using both descriptive and inferential statistics, including multiple regression and ANOVA. Based on the model summary, there exists a strong relationship between green procurement strategies and project sustainability (R = 0.806), and a further explanatory power of 65% (R² = 0.650). From the ANOVA results (F = 24.87, p < 0.001), all the predictors jointly and significantly affect project sustainability. Results from the individual predictors depicted inventory management and monitoring and evaluation having the strongest pull-on project sustainability. Nevertheless, supplier relationships and supplier selection also depicted strong effects. Additional diagnostic tests including linearity, normality and homoscedasticity were all met, supporting the reliability on the model. The findings make significant claims on inventory systems and consistent monitoring, and structured partnership with suppliers to drive project sustainability, in the devolved units’ projects. Among the key recommendations, the study urges the Isiolo County government to adopt lean inventory management, effect real time monitoring and evaluation frameworks and through deliberate policies, strengthen green supplier relationships. These recommendations, inferred from the study provide empirical evidence for counties to institutionalize green procurement strategies as a tool towards achieving sustainable development.
