The pursuit of sustainable project management practices is becoming increasingly important in contemporary project management discourse. This review explores the integration of sustainability principles and environmental considerations within project management frameworks, aiming to identify specific strategies that lead to eco-friendly project outcomes and foster long-term sustainability. By examining a broad range of scholarly works, empirical studies, and industry reports, this review highlights key methodologies for embedding environmental consciousness into project planning, execution, and evaluation. The findings reveal that incorporating sustainability principles into project management not only enhances project outcomes but also significantly reduces adverse environmental impacts. Specifically, the review identifies effective approaches such as life cycle assessment (LCA) and stakeholder engagement, which are shown to be instrumental in promoting sustainable practices across different project stages. Moreover, the study sheds light on common challenges, such as resistance to change and the lack of standardized sustainability metrics, and offers actionable recommendations for overcoming these barriers. In addition, the review discusses opportunities for advancing sustainable project management through the application of emerging technologies and cross-disciplinary collaboration. Insights from behavioral studies, environmental sciences, and management theories provide a comprehensive understanding of the factors driving the successful adoption of sustainability practices among project stakeholders. Ultimately, this review consolidates theoretical perspectives and empirical evidence to present a clear and detailed understanding of how sustainable project management practices can be effectively implemented to achieve environmentally responsible and enduring project outcomes.
