The Real Reason the Military Is Going Green

Retired Brig. Gen. Steven Anderson calls himself "an accidental environmentalist."

His epiphany about climate change started with a tactical problem. In 2006 and 2007, when he served as the military's chief logistician in Iraq, he coordinated the transport of millions of gallons of fuel across the country to power everything from vehicles to the large compressors used to cool individual tents—or, as Anderson puts it, for "air conditioning the desert." He was taking one casualty for every 24 fuel convoys, and he was doing 18 convoys a day. That's one casualty every other day. He needed to get the trucks off the road. He needed to find a way to reduce the military's fuel use.

"There's a direct relationship between energy and the military. The more energy consumed, the less effective you are militarily because you're more vulnerable," said Anderson, who reported to General David Petraeus. "They love to take out our field trucks. They make a big boom when they do."

Since then, Anderson, like many military leaders, has realized that guzzling oil makes the United States vulnerable in other ways. "I'm a soldier," Anderson said. "Why should I be concerned about climate change? Climate change brings about global instability. That makes the world more vulnerable and it's more likely that soldiers like myself will have to fight and die somewhere."

Never mind D.C. conservatives who claim to be tough on defense and suspicious of climate science: The Department of Defense isn't denying that climate change is a major national security threat. "The change is happening. It's just a reality," said retired Marine Col. Mark Mykleby, a former strategy assistant to the Joint Chiefs of Staff. "Science tells us it's coming our way."

The Defense Department first acknowledged climate change as a factor in its operations in its 2010 Quadrennial Defense Review. "[Climate change] may act as an accelerant of instability or conflict, placing a burden to respond on civilian institutions and militaries around the world," read the report.
