DHS Actions: Climate Change

The climate crisis poses a multi-level threat to the American people, the global community, and DHS operations at home and abroad. It is vital for the Department to provide leadership and act to minimize its own environmental impact, to promote resilience against the risks posed by climate change, and to facilitate adaptation, so as to reduce harms and threats to the American people and abroad.

Addressing the climate emergency is a priority for DHS as sea-level rise, extreme weather events, workforce health, and other direct and indirect impacts of climate change will affect the Nation’s preparedness and national security over the long term.  To combat this ongoing threat, DHS will implement a new approach to climate change adaptation and resilience, and it will do so with the sense of urgency this problem demands.

In the following video, Secretary Mayorkas announces new Department commitments to address the climate emergency at the White House Virtual Leaders Summit on Climate on April 22, 2021.

Overview of DHS Actions

DHS recognizes the threats climate change poses to the Homeland and the American people.  Sea-level rise, extreme weather events, drought, workforce health, and other direct and indirect impacts of climate change are already affecting the Homeland Security  enterprise and the Nation’s preparedness and national security over the long term.

Mitigation, Resilience and Adaptation

DHS leads the federal government in smart business solutions, approaches, and technology. The Department is committed to reducing greenhouse gas emissions, energy and water use, and generated waste as well as operating high-performance, sustainable buildings and fleets. DHS is committed to increasing resilience and adaptation through an assortment of measures designed to reduce the risks associated with climate change.

Stakeholder Engagement

Partnership constitute the foundation for securing the homeland. Preparedness for and resilience to catastrophic events requires the Department to collaborate with state, local, tribal, and territorial governments, and our brave local first responders. DHS work with the public must also:

  • Address the disproportionately high and adverse climate-related impacts disasters have on disadvantaged communities;
  • Reduce unnecessary barriers to participation and effectiveness;
  • Increase equity; and
  • Promote preparedness and resilience at the individual level.
