Global militaries generate 5.5% of worldwide greenhouse gas emissions yet report less than 10% of their actual carbon footprint to the UN. Scientists for Global Responsibility's November 2025 report reveals systematic underreporting requiring UN figures to be multiplied by 10-14 times to match reality. Military emissions remain exempted from international climate agreements including the Kyoto Protocol. The US military alone surpasses emissions of 140 countries, consuming 80% of US government fuel. NGOs including Conflict & Environment Observatory & Transform Defence intensify campaigns demanding accountability. The 2024 military spending climate cost reached $163 billion, 50% higher than previous years, while reporting quality deteriorates.
