1 Pentagon Fuel Use, Climate Change, and the Costs of War Neta C. Crawford 1 Boston University June 12, 2019 Summary In its quest for security, the United States spends more on the military than any other country in the world, certainly much more than the combined military spending of its major rivals, Russia and China. Authorized at over $700 billion in Fiscal Year 2019, and again over $700 billion requested for FY2020, the Department of Defense (DOD) budget comprises more than half of all federal discretionary spending each year. With an armed force of more than two million people, 11 nuclear aircraft carriers, and the most advanced military aircraft, the US is more than capable of projecting power anywhere in the globe, and with “Space Command,” into outer-space. Further, the US has been continuously at war since late 2001, with the US military and State Department currently engaged in more than 80 countries in counterterror operations. 2 All this capacity for and use of military force requires a great deal of energy, most of it in the form of fossil fuel. As General David Petraeus said in 2011, “Energy is the lifeblood of our warfighting capabilities.” 3 Although the Pentagon has, in recent years, increasingly emphasized what it calls energy security — energy resilience and conservation — it is still a significant consumer of fossil fuel energy. Indeed, the DOD is the world’s largest 1 Neta C. Crawford is Professor of Political Science at Boston University and Co-Director of the Costs of War project.

Conclusion

EvenastheUSsaysitwillscalebackthesizeofitsmilitarypresenceinAfghanistan,Iraq,andSyria,theUShasbegunamassivebuild-upofitsmilitarycapacities.TheUSmilitarybudgetislargerthanithaseverbeensincetheendoftheColdWar.TheUSseemstobeontracktocontinuepolicingthePersianGulfevenasitturnstowhatitperceivesisanemergingthreatfromChinaandhasanincreasingmilitarypresenceinAfrica.Alloftheseactivitiesdemandfuelconsumptionandarehencegreenhousegasemissionintensive. TheUShasanimportantpublicpolicydecisiontomake.Dowecontinuetoorientourforeignpolicyandmilitaryforceposturetowardensuringaccesstofossilfuels?Ordowedramaticallyreducetheuseoffossilfuels,includingthemilitary’sowndependency,andthusreducetheperceivedneedtopreserveaccesstooilresources?

Reductionsinmilitaryfuelusewouldbebeneficialinfourways.First,iftheUSweretodecreaseitsdependenceonoil,theUScouldreducethepoliticalandfuelresourcesitusestodefendaccesstooil.IftheUSfurtherreduceditsimportsofoilfromthePersianGulf,includingfuelusedbythemilitarytoprotectthoseimports,itcouldthenreevaluatethesizeoftheUSmilitarypresenceintheregionandreevaluateitsrelationshipwithSaudiArabiaandotheralliesintheregion.TheUSwouldreappoliticalandsecuritybenefits,includingreducingthedependenceoftroopsinthefieldonoilanddecreasingdependenceonoilandthosewhoprovideit.

Second,bydramaticallydecreasingfossilfuelconsumption,theUSmilitarywould

reduceoverallUSgreenhousegasemissionsandperhapspromotecarbonsequestration(takingcarbonoutoftheatmosphereandfixingitinthesoilandtrees).Therearemanywaystodothis,frommoremodestmeasuressuchasincreasingfueleconomyandusingalternativefuels,whichthePentagonhasbeguntodo.Somebaseclosureswillbenecessitatedbyclimatechangeitself.MoresignificantreductionsingreenhousegasemissionswillbegainedbyrestructuringtheUSmilitaryposture,includingreducingUSmilitaryoperationsandinstallationsworldwide,andclosingbasesintheUS.Baseclosurescouldalsoleadtosignificantcarbonsequestrationifthosepubliclandsarereforested.SeeAppendix2formodestsuggestionsforCongressionalaction.

Third,byreducingtheuseofgreenhousegas-emittingfuels(coupledwithemission

AtKyoto,theparties...tookadecisiontoexemptkeyoverseasmilitaryactivitiesfromany emissions targets, including exemptions for bunker fuels used in internationalaviation and maritime transport and from emissions resulting from multilateraloperations,suchasselfdefense,peacekeeping,andhumanitarianrelief.

This exempts from our national targets not onlymultilateral operations expresslyauthorized by the U.N. Security Council, such as Desert Storm or Bosnia, but,importantly,alsoexemptsmultilateraloperationsthat theU.S. initiatespursuant totheU.N.Charterwithoutexpressauthorization,suchasGrenada.104
