• Military emissions are difficult to track and often exempt from reporting.
• The US Defense Department is the largest energy user and emitter in the country.
• Estimates suggest global military emissions could be over 200 million metric tons of CO2 equivalent.
• War and post-war reconstruction also contribute to significant greenhouse gas emissions.

The lack of comprehensive accounting of military emissions may hinder efforts to reduce them, which could have significant implications for global climate goals. The sheer scale of estimated military emissions suggests that addressing this sector could be crucial in mitigating climate change, and may require international cooperation and agreements to standardize reporting and reduction strategies.
