Global Emissions Soar

The U.S. military is belching more global-warming pollutants than some industrialized nations, with about a third of its emissions occurring in major conflict zones such as Afghanistan and Iraq, according to a new study.

American armed forces -- with a globe-spanning array of bases, warships, planes and land vehicles -- are the world’s largest institutional emitter of greenhouse gases, topping countries including Sweden and Denmark, according to the study from Brown University’s Costs of War project. A spokesman for the Pentagon didn’t immediately return a request for comment.
