This research report investigates the multifaceted economic effects of the East African Crude Oil Pipeline (EACOP) on Uganda's economy. The EACOP, a $3.5 billion transnational project, is set to transport crude oil from Uganda’s oil fields in the Lake Albert region to the port of Tanga, Tanzania. The research adopted a quantitative approach using multiple linear regression analysis to establish relationships among the study variables. The dependent variables included economic growth and project success, while the independent variables comprised pipeline investment, employment creation, government revenue, foreign direct investment, policy and regulatory delays, environmental concerns, funding constraints, land acquisition disputes, stakeholder collaboration, government policy support, technological innovation, and community engagement. Specifically, pipeline investment, employment creation, government oil revenue, and foreign direct investment significantly influenced the country’s GDP growth, explaining about 74% of the variance in economic performance. The findings further indicated that policy and regulatory delays, environmental concerns, funding constraints, and land acquisition disputes negatively and significantly affected the success of the project, accounting for 65% of the variation in project performance. On the other hand, effective stakeholder collaboration, government policy support, technological innovation, and community engagement emerged as strong positive predictors of project success, explaining approximately 70% of the variance. It was concluded that the EACOP project is a transformative economic initiative capable of driving Uganda’s long-term development through infrastructure investment, employment creation, and revenue generation. However, its full potential could only be realized through addressing institutional inefficiencies, ensuring environmental sustainability, and strengthening social inclusion. The study further concluded that the success of EACOP largely depends on transparent governance, policy stability, and technological advancement supported by community participation. The study recommended that there should be harmonized and transparent policy frameworks, enhanced environmental protection measures, and strengthened financial management systems to ensure effective and accountable use of oil revenues. There should also be deliberate efforts to promote community engagement, technological innovation, stakeholder collaboration, and regional cooperation between Uganda and Tanzania. Additionally, there should be continuous monitoring, evaluation, and public reporting mechanisms to promote accountability and sustainability.
