U.S. Pentagon emits more greenhouse gases than Portugal, study finds

(Reuters News, 12 Jun 2019) Using and moving troops and weapons accounted for about 70% of its energy consumption.

The United States creates more planet-warming greenhouse gas emissions through its defense operations alone than industrialized countries such as Sweden and Portugal, researchers said on Wednesday.

The Pentagon, which oversees the U.S. military, released about 59 million metric tons of carbon dioxide and other greenhouse gases in 2017, according to the first study to compile such comprehensive data, published by Brown University.

The Pentagon's emissions were "in any one year ... greater than many smaller countries' greenhouse gas emissions," the study said.

If it were a country, its emissions would make it the world's 55th largest contributor, said Neta Crawford, the study's author and a political scientist at Boston University.

"There is a lot of room here to reduce emissions," Crawford said.

Request for comments to the Pentagon went unanswered.
