This document discusses environmental management systems (EMS). An EMS allows an organization to evaluate, control, and reduce its environmental impacts through a set of management processes. The commonly used framework is the ISO 14001 standard, which involves four phases - getting started, planning, implementation, and checking/acting. Key benefits of an EMS include improved efficiency, environmental management, and relationships with regulators. Successful implementation requires top management support, dedicated resources, strong implementation teams, and training.
