Abstract The concept of sustainability is becoming more widely understood, and green construction approaches are becoming more widely adopted. Both the public and private sectors are concerned about environmental sustainability, which is driving the rise. Some construction firms view the green building movement as a threat, while others see it as a significant chance to set themselves apart from other commercial builders and gain a competitive edge. His study examines how adopting green certification for projects influences developers', investors', and organizations
business decisions And propose mitigation measures to overcome the unfavorable impact on business.
