What if the machine supposed to protect the planet from future crises actually contributes to making them worse? Behind American military power lies a troubling paradox, where global security and climate change sometimes advance hand in hand.
A global military power with a carbon footprint exceeding that of many countries
At the heart of the American military system, one striking reality is its gigantic carbon footprint. Indeed, bases cover all continents. The air and naval fleets remain active constantly. The logistical chains are sprawling. Each operation therefore consumes an enormous amount of fuel.
According to research published in the scientific journal PLOS Climate, the cumulative emissions between 2010 and 2019 amount to approximately 636 million tons of CO2. Furthermore, this figure surpasses the annual emissions of many industrialized countries. It reveals an extraordinary energy power.
However, this observation is not only based on the number of soldiers. It is mainly due to a global energy-intensive infrastructure. As a result, deploying fighter jets or refueling aircraft carriers requires constant flows. Maintaining isolated bases further strengthens this dependence on fossil fuels.
A planetary network of bases and operations that relies on massive energy consumption
Behind every military mission lies a highly complex organization. In practice, the United States has hundreds of installations abroad. Each one requires a continuous supply of energy. Thus, this global web forms a permanent military logistics system.
Additionally, kerosene plays a central role. Indeed, combat and transport aircraft are among the most fuel-consuming equipment. This is in addition to land vehicles and ships. Consequently, the overall system creates an extraordinary energy consumption.
Even in times of relative peace, these activities continue. Exercises and patrols do not stop. Maintenance remains constant. Thus, this operation transforms the military into a discreet climate actor. However, its impact remains significant and often overlooked.
Rising military expenditures leading to a mechanical increase in emissions
A direct link is evident between military expenditures and emissions. Analyses show that when budgets decrease, fuel consumption also decreases. Thus, this correlation reveals a structural relationship between defense and climate. However, the current trend is moving in the opposite direction. Indeed, global military expenditures increased significantly in 2024.
They reached unprecedented levels. Consequently, this dynamic results in an increase in indirect emissions. Therefore, a question arises. Can the carbon footprint be reduced without reconsidering priorities? In practice, security still relies on massive energy power. Thus, any ecological transition in this field faces deep limitations.
An institution that acknowledges climate risk while contributing to its exacerbation
What remains most troubling is the official position of military institutions. Indeed, climate change is recognized as a major threat. Thus, rising sea levels, floods, and migrations are identified as factors of future conflicts. However, at the same time, military activities exacerbate these risks.
Thus, a loop is created between preparation and disruption. Consequently, military power also becomes an unintentional accelerator of climate disruption. Finally, this paradox goes beyond the American case. It questions the very notion of security. As environmental threats intensify, a persisting question remains: should we accumulate power or rethink what it truly means to be secure?
