Must shrink this war machine: US military bigger polluter than 140 nations

If the US military were a country, its fuel usage alone would make it the 47th largest emitter of greenhouse gases in the world, sitting between Peru and Portugal

The US military’s carbon bootprint is enormous. Like corporate supply chains, it relies upon an extensive global network of container ships, trucks and cargo planes to supply its operations with everything from bombs to humanitarian aid and hydrocarbon fuels. Our new study calculated the contribution of this vast infrastructure to climate change.

Greenhouse gas emission accounting usually focuses on how much energy and fuel civilians use. But recent work, including our own, shows that the US military is one of the largest polluters in history, consuming more liquid fuels and emitting more climate-changing gases than
