In 2021, the Biden Administration released Executive Order 14008: Tackling the Climate Crisis at Home and Abroad. In part, this order mandated a coordinated effort among U.S. foreign policy and national security agencies to address the effects of climate change, specifically focusing on the concepts of mitigation, adaptation, and resilience. The Department of Defense, the Department of State, and the U.S. Agency for International Development (USAID) separately created foundational documents that address the challenges of climate change, each addressing mitigation, adaptation, and resilience. Despite this common thread, each agency varies in how it perceives these concepts. How might the differing perceptions on the challenges of climate change affect policy coordination among these agencies? Using the Institutional Analysis and Development Framework and the Institutional Grammar 2.0, this study examines how the constitutive statements within these four seminal policy documents define the institutions that address climate change within the national security construct. From this parameterization, a policy network structure can be analyzed to explore the level of cooperation and coordination inherent in the newly created policy, particularly focusing on the constitutive properties of mitigation, adaptation, and resilience.
