Which of the following are types of Air Force Environmental Management Systems?

The correct answer identifies the types of Air Force Environmental Management Systems as installation, multi-site, and organizational.

Installation environmental management systems are tailored to manage environmental impacts at a specific base or facility, ensuring compliance with regulations and focusing on local concerns. Multi-site systems encompass multiple installations, providing a broader framework for environmental management practices across different locations, allowing for resource sharing and consistency in policy implementation. Organizational systems refer to the overarching framework and policies that guide the environmental management practices across the entire Air Force. This structure ensures that all levels of the organization, from command to local bases, are aligned in their efforts to manage environmental responsibilities effectively.

The other options do not accurately reflect the established types of Air Force Environmental Management Systems as recognized in current policies and frameworks. Thus, the distinction among installation, multi-site, and organizational is crucial for understanding how the Air Force addresses environmental management comprehensively at various levels.
