In the fall of 2018, Neta C. Crawford, a political science professor at Boston University, prepared to teach a class on climate change designed to help students think about the issue in a big-picture way. Crawford’s research expertise is in war, so she wanted to include a statistic on the military’s contribution to greenhouse gases.

“I thought, ‘Well, maybe I should just tell them what the emissions are for the U.S. military,’” Crawford says. “It was meant to be a line on a slide in a lecture.”

But when she went to look up the figure, she couldn’t find anything reliable. Instead, she found scattered and incomplete data on how much fuel the military consumed and how much carbon it emitted. The information that did exist largely didn’t include overseas operations, even though the United States had been at war for nearly two decades. Major categories of fuel consumption, like much of the fuel used for aviation, seemed to be missing.

In 1997, the Kyoto Protocol—the world’s first legally binding, international climate treaty—created a reporting loophole for militaries, exempting many of the greenhouse gases emitted during military operations from counting against a country’s emissions totals. While the 2015 Paris Accords did away with this exemption, they didn’t replace it with an obligation. Rather, the decision of whether to report military emissions—and how to calculate them—was left up to individual countries.

The result is a gap in our understanding of the United States’ climate footprint. [Continue reading…]
