In this eye-opening interview, Professor Neta Crawford discusses the research in her new book The Pentagon, Climate Change, and War focussing on the huge carbon footprint of the Pentagon — the world’s largest single greenhouse gas emitter. She tracks the interconnect long-term cycles of economic growth, and fossil fuel use-and growth of the US military. Crawford believes the most effective way to cut military emissions is to rethink U.S. grand strategy, which would enable the United States to reduce the size and operations of the military.
