When people express concern about climate change caused by greenhouse gas emissions, why do they ignore the Pentagon’s massive contribution? The Department of Defense burned 90 million barrels of oil in 2013, according to an article by Sharon Burke in the May/June 2014 issue of Foreign Affairs.

Using the U.S. Department of Environmental Protection’s carbon calculator, and multiplying 90 million barrels x 0.43 metric tons of carbon dioxide per barrel of crude oil, one can determine that the carbon footprint for 90 million barrels of crude oil is 38.7 million metric tons of carbon dioxide.
