Implementing Lean Construction for Sustainable Project Delivery: Enhancing Efficiency to Meet the UN SDGs

The construction industry is under increasing pressure to deliver cost-effective, environmentally sustainable projects. Lean Construction (LC) provides a framework for improving efficiency by minimizing waste and optimizing resource use, making it well-aligned with global sustainability goals such as the United Nations Sustainable Development Goals (UN SDGs). This paper explores the strategic application of LC principles to promote sustainable practices throughout the construction lifecycle. By reviewing LC's alignment with the SDGs, we propose a framework for integrating Lean practices to enhance environmental, social, and economic outcomes. The paper highlights how LC contributes to goals such as climate action, resource efficiency, and sustainable cities. Additionally, case studies and best practices are analyzed to demonstrate successful implementations, offering valuable insights for construction professionals seeking to balance efficiency with sustainability.
