Which certification must a project lead contractor have in construction environmental management?

The correct answer is C, ISO 14001, which is the certification specifically related to environmental management systems. This standard outlines criteria for establishing, implementing, maintaining, and improving an environmental management system within an organization. Achieving ISO 14001 certification demonstrates that a project lead contractor understands the importance of managing environmental responsibilities and is committed to sustainability practices, which are crucial in construction projects.

ISO 14001 provides a framework for organizations to reduce their environmental impact and ensure compliance with applicable regulations, making it a vital certification for contractors involved in projects governed by environmental management practices, like those under the Estidama Pearl Building Rating System.

In contrast, ISO 9001 focuses on quality management systems, ISO 50001 addresses energy management, and ISO 45001 pertains to occupational health and safety management. While these standards are important for various aspects of construction and organizational operation, they do not specifically address environmental management, which is the key requirement for a project lead contractor in this context.
