The US military is one of the largest polluters in history, emitting more carbon dioxide than entire countries like Denmark or Portugal. If the US military were a nation-state, it would be among the top 50 largest emitters of greenhouse gases globally. With over 750 overseas military bases and a vast infrastructure, the US military's carbon footprint is significant, and its emissions are contributing to climate change. China, on the other hand, has one military base, but the rivalry between the two countries leads to an increase in military emissions as they respond to the security dilemma. The US military's pollution has had devastating effects on the environment and human health, with nuclear weapons tests and water contamination being notable examples.

The US military's nuclear weapons tests
The US military is one of the largest polluters in history, with its carbon footprint being compared to that of entire countries. If the US military were a nation-state, it would be the 47th largest emitter of greenhouse gases in the world.
One of the most devastating cases of US military pollution activity was the nuclear weapons tests they performed in the Marshall Islands. From 1946 to 1958, the United States tested 67 nuclear weapons in what is now known as the Republic of the Marshall Islands. These tests have been said to be 1,000 times greater than the Hiroshima bomb, and the fallout from the tests had the most significant impact on four northern atolls: Enewetak, Bikini, Rongelap, and Utrok. Each of these islands was evacuated due to radiation, and residents continue to suffer from radiation poisoning, birth defects, leukaemia, and cancer, more than 75 years later.
The United States conducted six atomic tests before the Soviet Union developed their first atomic bomb (RDS-1) in 1949. The US had a dedicated test site on its own territory (the Nevada Test Site) and also used a site in the Marshall Islands (Pacific Proving Grounds) for atomic and nuclear testing. During the 1950s, these tests included new hydrogen bomb designs and improved fission weapon designs. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield of approximately 20 kilotons of TNT.
Nuclear weapons tests are designed to gain information about the effects of weapons on structures, equipment, organisms, and the environment. They are used to assess and improve survivability in the event of nuclear explosions and to develop the tactics of nuclear warfare. Atmospheric testing involves explosions that occur in the atmosphere, generally as devices detonated on towers, balloons, barges, or islands, or dropped from airplanes. The United States performed nuclear weapons tests from 1945 to 1992, with an official count of 1,054 nuclear tests, including 215 atmospheric and underwater tests.
The US military has recognised climate change as a threat multiplier and has invested in developing alternative energy sources like biofuels. However, these comprise only a tiny fraction of their spending on fuels, and the military's vast infrastructure continues to rely heavily on hydrocarbons.

US military wars' impact on economies
The US military's involvement in wars has had a significant impact on the economy, and this impact is often negative. While there may be short-term economic gains, the long-term costs of war are severe and numerous. War is expensive and destructive, affecting long-term economic growth through population changes, reduced investment, and worsening educational outcomes.
A study of six major US wars, including World War II, the Vietnam War, and the wars in Afghanistan and Iraq, found that the costs of war negatively affect the national economy, taxes, debt, jobs, investment, and inflation. The study showed that in most wars, public debt, inflation, and tax rates increase, while consumption and investment decrease. Military spending also diverts funds from more productive government investments in high-tech industries, education, infrastructure, and social welfare, all of which are crucial for long-term economic growth.
Military spending by the US federal government is often considered vital to supporting employment and economic recovery. However, research consistently shows that military spending produces fewer jobs than investments in education, health, infrastructure, or clean energy. For instance, $1 billion in military spending creates approximately 11,200 jobs, while the same amount spent on education or healthcare would generate over 26,000 and 17,000 jobs, respectively. This is because sectors like education and healthcare are more labor-intensive, and a greater percentage of spending stays within the US, creating more domestic jobs.
The US military-industrial-congressional complex (MICC) is a powerful system that influences decisions to go to war. This complex involves the deep integration of arms manufacturing in the national economy and the revolving door between lawmakers and weapons lobbyists. The arms industry uses lobbying and campaign donations to promote spending that serves its interests, often independently of America's actual security needs. This has led to the expansion of the military-industrial complex into Silicon Valley, with a growing portion of the Defense Department's spending going to tech firms.
The negative economic impact of military spending is particularly apparent in wealthier countries, including the US. Over a 20-year period, a 1% increase in military spending decreased economic growth by 9%. While there may be short-lived gains for certain industries, these do not offset the long-term economic costs of war.
In conclusion, the US military's involvement in wars has had a significant and often negative impact on the economy. War and military spending divert resources from more productive investments, reduce transparency in government spending, and hinder long-term economic growth.

US military's carbon footprint
The US military is one of the largest polluters in history, with a vast carbon footprint. It emits more carbon dioxide than entire industrialised nations, such as Portugal and Denmark, and if it were a country, it would be the 47th largest emitter of greenhouse gases. The US military's carbon footprint is so large due to its extensive global network of trucks, cargo planes, and container ships, as well as its reliance on fossil fuels for its operations. The Department of Defense is the world's largest institutional consumer of petroleum, and 70% of its energy is consumed by moving troops and equipment. The US military also owns a lot of property, with 585,000 facilities spread over 27 million acres in 160 countries, requiring energy for heating and electricity.
The US military's carbon footprint has devastating consequences for the environment and human health. For example, the US military has performed nuclear weapons tests in the Marshall Islands and the Navajo Indian reservation, resulting in radiation poisoning, birth defects, and cancer for residents. The US military has also contaminated groundwater in North Carolina, leading to cancer and other illnesses for servicemen. Additionally, the US military's intervention in Iraq has contributed to the desertification of 90% of Iraqi territory, destroying the economy and forcing the country to import most of its food.
Despite the US military's significant contribution to climate change, it tends to be overlooked in studies and is not included in decarbonisation efforts. This is partly due to the challenge of gathering data about the US military's fuel consumption and emissions, especially overseas operations. The US military's withdrawal from the 1997 Kyoto Protocol also exempts it from reporting emissions, although the 2015 Paris Accords removed this exemption.
Reducing the US military's carbon footprint requires addressing its fuel consumption and emissions in domestic policy and international climate treaties. This includes reducing the Pentagon's budget and capacity to wage war, as well as transitioning to alternative energy sources and reducing overall military spending and deployment.

US military's overseas bases
The US military is one of the largest polluters in history, with a carbon footprint that surpasses that of entire countries. A 2019 report by Durham and Lancaster University found that the US military consumes more liquid fuels and emits more carbon dioxide than most nations, and if it were a country, it would rank 47th in greenhouse gas emissions. The US military's vast infrastructure and global operations contribute significantly to its pollution output.
The US military maintains a significant number of overseas bases, with a global network of trucks, cargo planes, and container ships supporting its operations. As of July 2024, the US operated at least 128 military bases outside its national territory, spanning 49 countries. Japan hosts the most US military bases, with 14, followed by the Philippines (9) and South Korea (8). Camp Humphreys in South Korea is the largest overseas base in terms of area. The presence of these bases in non-democratic states has drawn criticism, with accusations of collaboration with oppressive regimes.
The US military's overseas bases serve strategic security priorities, particularly in Europe and East Asia. For example, the base in Djibouti is situated on the Bab-el-Mandeb Strait, a key shipping route connecting the Gulf of Aden and the Red Sea. This strategic location has attracted other nations, including political rivals like China. The US military's presence in Syria has also been a source of controversy, with Syrian officials considering it an "illegal" occupation without their consent.
The environmental impact of the US military's activities, including its overseas operations, has been significant. Nuclear weapons tests in the Marshall Islands and the Navajo Indian reservation, water contamination at Camp Lejeune in North Carolina, and the release of radioactive toxins from the Hanford Nuclear Reservation in Washington state are among the most harrowing instances of US military pollution. The US military's contribution to climate change has also exacerbated the economic and population challenges in countries where it has intervened, such as Iraq, which now faces desertification and increased food imports.
Addressing the US military's carbon footprint is crucial in mitigating climate change. As one of the world's largest consumers of hydrocarbons, the US military's efforts to develop alternative energy sources like biofuels only comprise a tiny fraction of its fuel spending. Reducing the Pentagon's budget and shrinking its capacity to wage war could significantly decrease global demand for liquid fuels. However, this requires breaking the cycle of militarization and emissions, which is a challenging task in the face of potential rivals like Russia and China.

US military's fuel consumption
The US military is one of the largest consumers of liquid fuels in the world. In 2007, the Department of Defense (DoD) was responsible for 93% of all US government fuel consumption, with the Air Force consuming the most at 52%, followed by the Navy at 33% and the Army at 7%. The DoD uses 4.6 billion US gallons of fuel annually, averaging 12.6 million US gallons per day.
The US military's fuel consumption has led to it being labelled as one of the largest climate polluters in history. A 2019 report by Durham and Lancaster University found that the US military consumes more liquid fuels and emits more CO2 than most countries. If the US military were a country, it would be the 47th largest emitter of greenhouse gases. The report also highlighted the US military's vast infrastructure and its reliance on a global network of trucks, cargo planes and ships to supply its operations.
The US military's fuel consumption has had significant environmental and human impacts. Two notable cases of US military pollution include nuclear weapons tests in the Marshall Islands and on the Navajo Indian reservation, resulting in radiation poisoning, birth defects and cancer. Additionally, the US military's reliance on fossil fuels contributes to climate change, which has led to the desertification of 90% of Iraqi territory, affecting the country's economy and food security.
Recognizing the environmental impact of its fuel consumption, the US military has taken some steps towards reducing its dependence on fossil fuels and investing in renewable energy sources. The Defense Department has set a goal to improve energy use in military operations, investing $9 billion through 2017. The Air Force, the largest purchaser of renewable energy within the Federal government, has prioritized the use of synthetic fuel blends and biofuels. The Marine Corps has also established the Expeditionary Energy Office, aiming to reduce the need for liquid fossil fuel by 50% by 2025.
