The study employed a cross-sectional design. The study also used quantitative approaches in collecting and analyzing the data both descriptively and inferentially. The study population was 675 manufacturing entities. Using the purposive sampling technique, the study took a sample of 248. Data were obtained from 186 usable questionnaires. The researcher applied Statistical Package for Social Scientists (SPSS) to test all four hypotheses.

Results indicate that Pearson’s correlation results indicate a relatively moderate, positive and significant association between Green Sourcing and Environmental Sustainability in Kampala industries (r= 0.558, sig .000, p< .01) ; Multiple regression results indicated that Green sourcing (β = 0.387) was found to significantly predict Environmental Sustainability in Kampala industries. Green sourcing has a significant effect on Environmental Sustainability in Kampala industries.
