The United States military was one of the first institutions in government to acknowledge the threat posed by climate change, as well as the science behind it, and yet it remains the largest single energy consumer in the country and the largest institutional greenhouse gas emitter in the world. To talk through this strategic disconnect, Lawfare managing editor Tyler McBrien sat down with Dr. Neta Crawford, Montague Burton Chair in International Relations at the University of Oxford, co-director of the Costs of War study at Brown University, and author of the new book, “The Pentagon, Climate Change, and War: Charting the Rise and Fall of U.S. Military Emissions.” They discussed what Dr. Crawford calls the irony and tragedy of the military’s carbon emissions, how war drives emissions and industrialization, and why climate activists may be skeptical about framing climate as a security issue.
