Sustainability and Environmental Programs

Mission — The Office of Sustainability and Environmental Programs (SEP) functions as part of the Office of the Chief Readiness Support Officer, through leading, governing, integrating, managing and resource planning of sustainability, environmental compliance, energy, and environmental planning and historical preservation programs.


SEP supports and enhances DHS mission readiness and resilience by ensuring that energy and environmental programs, as established by laws, public policies and best practices, are appropriately integrated throughout activities, operations and programs of DHS.


SEP plays an important role in securing the nation and ensuring the Department can prepare for, respond to, and mitigate against the full spectrum of threats both natural and man-made. Under the leadership of an Executive Director, the work of SEP is an essential aspect of field efficiency efforts, and is performed through three main focus areas with overlapping scopes of responsibility:

  • Energy Management and Resilience
    • DHS Wind Farm Policy
  • Environmental Management and Sustainability
  • Environmental Planning and Historic Preservation Programs

SEP provides policy, guidance, training, technical support, and Department oversight through coordination with DHS Components and consultation with the public. As a result, energy management, resilience, environmental management and sustainability, and environmental planning and historic preservation programs, are appropriately integrated throughout activities, operations, and programs of DHS and its stakeholders.
