Neta C. Crawford, a political scientist at Oxford University, aims to fix that in her new book, The Pentagon, Climate Change, and War: Charting the Rise and Fall of US Military Emissions. 

Although the Pentagon has been at the forefront of climate change research since the mid-20th century, Crawford writes, the US Department of Defense is also the single largest institutional fossil fuel user in the world. 

Since 2001, the military has been responsible for 77 to 80 percent of federal energy consumption. 

The DOD maintains more than 560,000 buildings on about 500 bases around the world, making up a large portion of its emissions. And like a goliath multinational corporation, it relies on an extensive network of fossil-fueled equipment's  from dropping bombs to delivering humanitarian aid.

And although recent research has demonstrated that the US military is one of the largest polluters in history, it still tends to be overlooked in climate change studies.
