The US military is the world's largest consumer of oil
The US military is the world's single largest consumer of oil and, as a result, one of the world's top greenhouse gas emitters. In 2017, the Pentagon's greenhouse gas emissions totalled over 59 million metric tons of carbon dioxide equivalent. If the Pentagon were a country, it would have been the world's 55th largest greenhouse gas emitter, with emissions larger than Portugal, Sweden or Denmark. The US military uses more oil than any other institution in the world, with over 100 million barrels of oil consumed annually to power ships, vehicles, aircraft, and ground operations. This is enough for over 4 million trips around the Earth, assuming 25 mpg.
The US Department of Defense is one of the largest single consumers of energy worldwide, responsible for 93% of all US government fuel consumption in 2007. The Air Force is the largest user of fuel energy in the federal government, accounting for 52% of the DoD's fuel consumption, followed by the Navy at 33% and the Army at 7%. The DoD uses approximately 4.6 billion US gallons of fuel annually, averaging 12.6 million US gallons per day.
Recognizing the environmental and strategic implications of its oil consumption, the US military has prioritized renewable energy strategies. The DoD established the Office of the Assistant Secretary of Operational Energy Plans and Programs in 2010 to coordinate energy issues and promote renewable energy technologies. The DoD also plans to invest $9 billion to improve energy use in military operations through 2017, including solar power installations on base housing and the development of biofuel refineries that meet military specifications.
The US military's efforts to reduce its dependence on oil are driven by both environmental and tactical considerations. Oil dependence has strategic implications for military operations, particularly in the Middle East, and the large convoys required to transport oil on the battlefield present a significant target. Additionally, reducing oil consumption can enhance force safety and budget stability while mitigating climate change.

The US military is one of the world's top greenhouse gas emitters
The US military is the world's single largest consumer of oil, and as a result, it is one of the world's top greenhouse gas emitters. In 2016, the Defense Department consumed about 86 million barrels of fuel for operational purposes. The B-2 stealth bomber, for example, holds over 25,600 gallons of jet fuel and emits more than 250 metric tons of greenhouse gas over a 6,000-nautical-mile range. The US military's emissions are estimated to be more than those of most countries, with 51 million tons of carbon dioxide emitted in 2020. If the US Department of Defense were a country, it would rank 34th in the world in average daily oil use.
The US military's vast fuel consumption and emissions are due in large part to its aircraft. The Air Force alone uses 10% of the nation's aviation fuel, with 82% of that being jet fuel. The workhorse equipment used by the military is notoriously inefficient, with even non-armored vehicles like the Humvee getting only 4 to 8 miles per gallon. Aircraft, however, are the most fuel-thirsty, as evidenced by the B-2 stealth bomber's fuel consumption and emissions.
The US military has taken some steps to reduce its fuel consumption and emissions. The Marine Corps established the Expeditionary Energy Office to reduce the need for liquid fossil fuel by 50% by 2025, using liquid fuel only for mobility. The Defense Department invested $9 billion to improve energy use in military operations through 2017, and the SolarStrong program installed 300MW of PV installations on 120,000 roofs of base housing. The Air Force, the federal government's leading purchaser of renewable energy, has also been working to certify its entire fleet on coal-to-liquid synthetic fuel blends and plans to fuel half of its domestic transportation with US-produced synthetic blends by 2016.
Despite these efforts, the US military's emissions remain a significant concern. In 2018, Neta C. Crawford, a political science professor at Boston University, attempted to find data on the military's greenhouse gas emissions but found the information to be scattered and incomplete, with major categories of fuel consumption, such as aviation fuel, seemingly missing. This lack of transparency and comprehensive data makes it challenging to fully grasp the scope of the military's emissions and implement effective reductions. The Deputy Secretary of Defense, Kathleen Hicks, acknowledged the need to optimize energy use and reduce emissions, with President Joe Biden setting a goal of net-zero greenhouse gas emissions by 2050 for the Department of Defense.
