Study finds the Pentagon creates more greenhouse gas emissions than some industrialized countries

A new study has found that the Pentagon emits more greenhouse gasses in one year than several industrialized countries, including Sweden and Portugal.

The Defense Department is the world's single largest consumer of oil, and in 2017, the Pentagon released 59 million metric tons of carbon dioxide and other greenhouse gasses into the atmosphere, the study states. "If it were a country, it would have been the world's 55th largest greenhouse gas emitter," writes study author Neta Crawford, a political scientist at Boston University.

Most of the Pentagon's energy consumption is related to maintaining 560,000 buildings at 500 military installations and the jet and diesel fuel used to move soldiers and weapons. Crawford said the military has been using more efficient vehicles, and it would make a huge difference if the Pentagon started rethinking certain missions and whether they are necessary. "There is a lot of room here to reduce emissions," Crawford said.
