Beginning with the emergence of Green Project Management (GPM), GPM has become an increasingly important framework for incorporating environmental, social, and governance considerations in order to achieve long-term organizational value and sustainability during the project delivery process. This research paper assesses the effects of practicing GPM on both long-term cost-benefit analysis and the creation of organizational value by conducting a thorough literature review of all relevant contemporary literature. The study demonstrates that the application of GPM practices directly and positively influences organizational performance in several ways, such as cost savings, risk reduction, increased stakeholder engagement, and sustainable competitive advantages. As demonstrated in the findings, organizations that implement GPM practices will realize significant long-term financial gains in addition to their initial investment with benefit-to-cost ratios in the range of 4.8 to 30 in Green Infrastructure Projects. The study identified the Triple Bottom Line Framework as the methodological framework for assessing the impact of GPM across the economic, environmental, and social dimensions. Additionally, the study indicates that key mechanisms of how GPM generates organizational value are improved resource efficiency, enhanced reputation/brand value, decreased operational costs, and increased stakeholder relationships. Finally, the study concluded that GPM is a strategic necessity rather than an operational option, with organizations that integrate sustainability principles into their business model achieving greater long-term performance and resilience. Recommendations for practitioners include implementing Life Cycle Costing methodologies, engaging stakeholders throughout the project lifecycle, and leveraging digital technologies to improve decision-making and transparency in the sustainable delivery of projects.
