An EMS relies on a cycle of continuous improvement consisting of four steps – Plan, Do, Check and Act. This model serves as a framework for installations to clearly identify, prioritize, manage, and check progress toward meeting environmental objectives and targets, minimizing environmental risks, and identifying areas for continual improvement of mission support and environmental performance.
The International Organization for Standardization developed the ISO 14001 standard to provide a set of internationally recognized criteria for EMS. The Army adopted the ISO 14001 because it provides a proven, systematic approach to managing the environmental risks associated with an organization's activities, products and services. ISO 14001 offers flexibility, allowing the organization to pursue its own performance goals as long as they are consistant with its environmental policy. Organizations commit to continuous improvement, prevention of pollution and compliance with legal requirements.
An EMS applies a methodical approach to identifying risks, focusing resources, measuring performance and meeting mission requirements. Through an EMS, an installation can manage the full scope of its environmental programs. Many installations integrate strategic sustainability efforts with their EMS. This ability to incorporate diverse initiatives into one encompassing system, along with the information power it provides, enables garrison commanders to meet their responsibilities to strengthen Soldier and Family readiness, enhance installation sustainability, improve infrastructure and enable business transformation.
EMS uses the Environmental Performance Assessment System (EPAS) program to provide external audits and support internal audits that help Army commanders attain, sustain and monitor compliance with federal, state and local environmental laws and regulations, and DoD and Army requirements. EPAS now provides the external check on an installation's EMS that enables continuous improvement of the management system.
PLAN
Establish the system processes and set objectives to develop programs necessary to deliver results in accordance with the installations environmental or sustainbility policy. For example: "Set objectives targets and programs to increase availability of training lands." "Review the environmental aspects of the installation's activities, products and services."
DO
Implement the system processes through defined roles and responsibilities, systematic communication, training and documented controls, including: "Procedures in place to ensure current shop operational controls are in place at the point of use." "Cross-functional teams guide work toward EMS/sustainability objective or goal."
CHECK
Monitor and measure results by periodically checking compliance, auditing the system, and ensuring effectiveness of corrective or preventive actions such as: "The installation maintains its Installation Corrective Action Plan to ensure the effectiveness of preventive actions." "Environmental officers and environmental inspectors evaluate compliance and ensure effective communication."
ACT
Take action to continually improve the performance of the EMS. For instance: "The Environmental Quality Control Committee guides the EMS and ensures its continued suitability, adquacy and effectiveness."
