Military operations and wars significantly contribute to climate change and biodiversity loss, yet their environmental impacts are often overlooked due to national security concerns. The military-industrial complex is a major source of greenhouse gas (GHG) emissions, with the U.S. military alone accounting for 31.2% of historical emissions. Military activities, including fuel consumption, base operations, and weapon production, generate substantial emissions, with the U.S. military's fuel usage equivalent to that of a major nation. Wars and conflicts exacerbate environmental damage through fuel use, destruction of ecosystems, and pollution. For example, the Vietnam War caused widespread ecological damage, while the draining of the Mesopotamian Marshes and ISIS attacks on oil wells in Mosul led to significant environmental degradation. These conflicts also lead to biodiversity loss, ecosystem destruction, and long-term environmental hazards, such as residual radiation from nuclear weapons. The lack of transparency in military emissions reporting, due to national security concerns, creates a "military emissions gap." Only a few countries report their military emissions in line with UN guidelines, while others keep the data classified. Efforts are underway to address this blind spot, with environmental groups and scholars advocating for more comprehensive reporting. However, reducing military emissions presents complex challenges, including the long lifecycles of military equipment, reliance on fossil fuels, and the need for structural changes in military operations. The environmental and humanitarian impacts of war and military operations underscore the urgent need for global peace and environmental management. Peace is not only a moral imperative but also essential for preserving biodiversity and mitigating climate change. The call for peace is intertwined with the need for sustainable and peaceful activities, as war and conflict deplete resources and create long-term environmental and social harm. As the military sector becomes more aware of its environmental impact, there is a growing push for transparency and accountability in military emissions. This shift is crucial for addressing the global climate and biodiversity crises.Military operations and wars significantly contribute to climate change and biodiversity loss, yet their environmental impacts are often overlooked due to national security concerns.
