What family of standards provides guidance for developing environmental management systems?

The correct choice is ISO 14000, which is a family of international standards specifically focused on environmental management systems (EMS). These standards provide organizations with guidelines and frameworks to create, implement, maintain, and improve their environmental management efforts. This is crucial for ensuring that enterprises effectively manage their environmental responsibilities and comply with applicable laws and regulations.

The ISO 14000 series emphasizes a systematic approach to environmental management, which includes continuous improvement, stakeholder engagement, and integrating environmental considerations into business processes. This structured framework helps organizations assess their environmental impact, set objectives, and track their performance over time, fostering a culture of sustainability.

The other options relate to different areas of management standards. ISO 50000 focuses on energy management, which, while related to sustainability, does not cover the full spectrum of environmental management. ISO 15000 is associated with e-business and electronic commerce, and ISO 9000 pertains to quality management systems, which are essential but do not focus specifically on environmental aspects. Hence, ISO 14000 is the most relevant family of standards when it comes to developing environmental management systems.
