The U.S. military and armed forces of countries around the world will no longer be automatically exempted from emissions-cutting obligations under the U.N. Paris climate deal.
Although the U.S. never ratified the Kyoto Protocol, it won an opt-out from having to fully report or act on its armed forces’ greenhouse-gas emissions, which was then double-locked by a House national-defense authorization bill in 1999.
Under the Paris agreement, countries would not be obliged to cut their military emissions but, equally, there would be no automatic exemption for them either.
U.S. officials privately say that the deal adopted on Saturday has no provisions covering military compliance one way or another, leaving decisions up to nation states as to which national sectors should make emissions cuts before 2030.
“If we’re going to win on climate we have to make sure we are counting carbon completely, not exempting different things like military emissions because it is politically inconvenient to count them,” Stephen Kretzmann, Oil Change International’s director, told The Guardian. “The atmosphere certainly counts the carbon from the military. Therefore we must as well.”
The U.S. military is widely thought to be the world’s biggest institutional consumer of crude oil, but its emissions-reporting exemptions mean it is hard to be sure.
According to Department of Defense figures, the U.S. army emitted more than 70 million metric tons of CO2 equivalent per year in 2014. But the figure omits facilities including hundreds of military bases overseas, as well as equipment and vehicles.
Activities including intelligence work, law enforcement, emergency response, tactical fleets, and areas classified as national-security interests are also exempted from reporting obligations.
The U.S. military requested the original Kyoto exemption on national-security grounds. While the Obama administration is not looking to the military for emissions cuts before 2030, U.S. Republicans argue that future presidents, such as the socialist candidate Bernie Sanders for the Democrats, could.
“Lets face it, vast swathes of our military are big carbon emitters—tanks, Jeeps, humvees, jet planes—and of course much of our navy is not nuclear-powered, so [the Paris agreement] could be used as a trojan horse,” said Steven Groves, a senior research fellow at the Heritage Foundation.
He added: “This might be a good opportunity for people concerned with national security to go to Congress and get some type of legislative exemption in the same way as was done during the Kyoto time period.”
One of the first advocates of the House double-lock on the Kyoto exemption was Dick Cheney, according to a book called The Greening of the U.S. Military by Terry Lee Anderson, a senior fellow at Stanford University. Cheney argued that the Kyoto clause would not cover U.S. unilateral actions in a letter, which was also signed by other former security officials.
The Iraq war was responsible for 141 million metric tons of carbon releases in its first four years, according to an Oil Change International report. On an annual basis, this was more than the emissions from 139 countries in this period, or about the same as putting an extra 25 million cars onto U.S. roads for a year.
The paper found that projected U.S. spending on the Iraq war could cover all global investments in renewable energy needed to halt global-warming trends in the period to 2030.
