Final week, all 27 EU heads of state met in Brussels to supervise the continent’s largest navy growth in a long time—a response to Chilly Battle-level tensions. But, as Europe re-arms, an even bigger risk looms: local weather collapse, which no arsenal can deter.
With unchecked local weather change poised to halve world GDP in a long time, safety now hinges on rethinking power itself—beginning with the navy.

Insurance coverage specialists warn that unchecked climate change could slash global GDP by 50% in the coming decades, destabilizing economies and societies alike. Safety isn’t nearly protection budgets and troop deployments; it’s about sustaining the financial foundations that nations depend on.
As Europe re-arms, the vital query is that this: Will it put money into a navy that locks itself into fossil gas dependence—or will it seize the chance to guide in inexperienced protection innovation, securing each its nationwide safety and financial future?

The Case for a Fossil-Free Army
Army Emissions: A Hidden Weak spot
Fashionable warfare is fueled by oil, and that’s an issue.
- International militaries account for as much as 5.5% of total CO₂ emissions, surpassing the emissions of whole nations like Japan or Russia.
- The U.S. Division of Protection alone emits greater than Sweden or Portugal, making it the world’s largest institutional consumer of petroleum .
- Gasoline transport missions in Iraq and Afghanistan uncovered the excessive price and vulnerability of oil-dependent provide chains. In 2007 alone, an estimated 170 servicemembers were killed or wounded safeguarding gas convoys—casualties that starkly illustrate how these missions, relentlessly focused by insurgents, grew to become a deadly legal responsibility for American troops.
European navy leaders acknowledge this threat:
“If the navy are the one ones utilizing fossil fuels, then we might want to do our personal exploration, our personal refineries, our personal logistics of the entire gas chain, and that can’t be actuality.”
“We thought we had a take care of Gazprom, however we truly had a take care of Mr. Putin.”
A fossil-free navy would considerably cut back these vulnerabilities, lowering dependence on adversary-controlled power sources and unstable gas provide chains. Whereas jet gas and diesel stay important on account of their unmatched power density, a transparent, phased transition towards biofuels, hydrogen, and electrification—beginning with logistics and base operations—may meaningfully decrease dangers from geopolitical threats, unstable power markets, and rising operational prices.
Critics argue that fossil fuels’ power density stays unmatched for fight, however phased transitions—beginning with bases and logistics—show the shift is possible with out sacrificing readiness.
The Greatest Nationwide Safety Danger Is Not a International Adversary
But navy emissions are solely a part of the problem. The deeper problem is power dependency itself—one which exposes provide chains to geopolitical shocks and battlefield vulnerabilities.
For many years, navy energy has relied on oil-fueled logistics chains, diesel-powered armored autos, and jet fuel-reliant air forces. However as local weather change accelerates, this dependence has turn out to be a direct nationwide safety threat.
That threat isn’t simply tactical—it’s financial. As talked about earlier than, insurance coverage specialists warn that unchecked local weather change may slash world GDP by 50% within the coming a long time—pushed by crop failures, mass migration, and useful resource wars—triggering financial and social destabilization on a scale by no means seen earlier than.
Geopolitical power shocks additionally stay a big risk. Russia’s invasion of Ukraine uncovered Europe’s harmful reliance on Russian fossil fuels, a vulnerability that instantly extends to navy power provide chains.
In the meantime, China is quickly positioning itself as a world chief in navy clear power innovation. From hydrogen-powered drones and AI-driven autonomous fight autos to nuclear-powered warships, China is integrating next-generation expertise into its protection technique. Maybe most ambitiously, it’s exploring space-based solar power—aiming to beam limitless, renewable power from orbit to maintain navy operations with out reliance on fossil fuels. If Europe delays its transition, it dangers not solely an financial setback but in addition a strategic drawback within the energy-driven warfare of the longer term.
Protection Spending Has Traditionally Pushed Innovation
Rheinmetall participating in EU challenge for sustainable ahead working bases
“A big enchancment in power ratios can be achieved for navy operations. Optimizing power effectivity throughout deployed operations locations particular calls for on expertise. We sit up for utilizing our abilities and expertise to assist our clients’ sustainability targets.”
Army R&D has reworked world industries earlier than, and it may achieve this once more:
- The Web & GPS- Initially developed for navy use, now important for world commerce.
- Medical Developments– Battlefield medication has revolutionized civilian trauma care.
- Nuclear Energy– First utilized in navy submarines earlier than turning into a world fossil-free power supply.
A European dedication to inexperienced navy expertise would guarantee each strategic dominance and cleantech management.
Confirmed Examples of Fossil-Free Army tech

A complete array of current examples show that clear protection tech just isn’t a pipe dream. Sweden’s JAS 39 Gripen fighter has efficiently flown on 100% biofuel, demonstrating that high-performance navy plane can transition to renewable power. In France, the navy has applied “Eco Camp 2025,” deploying solar-powered discipline bases to scale back reliance on gas convoys. In the meantime, the British Military has developed hybrid-electric armored vehicles that decrease gas consumption and enhance stealth, with future fashions probably incorporating hydrogen propulsion to additional cut back emissions.
The battle in Ukraine
The battle in Ukraine is demonstrating the strategic benefit of low-emissions weaponry. Ukrainian forces have efficiently built-in low-cost, commercially accessible drones into frontline operations, lowering reliance on fuel-intensive navy autos and plane. These drones supply enhanced battlefield agility, cost-effectiveness, and tactical flexibility—delivering precision strikes and reconnaissance at a fraction of the price and carbon footprint of conventional weapons techniques. This shift not solely improves operational effectivity but in addition underscores the way forward for warfare: adaptable, decentralized, and fewer depending on fossil fuels.
China taking the lead
The race for clear navy expertise is already underway. China has quickly positioned itself as a pacesetter in inexperienced protection innovation, integrating next-generation power options into its navy technique. If Europe delays, it dangers not solely an financial setback but in addition lacking a vital alternative to guide the way forward for protection.
In 2024, China’s funding in clear power reached almost the size of world fossil gas investments, totaling roughly $940 billion. Greater than half of this funding went into its electrical car, battery, and photo voltaic industries, considerably outpacing different world markets. Importantly, Beijing controls vital minerals like lithium, copper, and uncommon earth metals, securing a key benefit within the subsequent technology of navy and civilian power
If Europe fails to transition to a fossil-free navy, it dangers not solely being outmaneuvered in battle but in addition turning into strategically depending on overseas power applied sciences.
Conclusion: Fossil-Free Army Energy: Europe’s Financial Lifeline
The elemental function of navy energy is to not wage battle, however to forestall it. A well-equipped, energy-independent navy serves as a deterrent, lowering the chance of battle. However whereas a robust navy can deter adversaries, it can’t deter local weather collapse.
If Europe integrates clear power innovation into its navy modernization, it’ll safe long-term power independence, releasing itself from unstable oil markets and making certain operational resilience. By main the world in navy cleantech, Europe has the chance to realize each strategic and financial dominance, setting the worldwide commonplace for sustainable protection. On the similar time, investing in fossil-free navy expertise will cut back world safety dangers, addressing climate-driven instability earlier than it escalates into full-scale battle.
Nevertheless, if Europe stays locked into one other century of fossil gas dependence, it dangers being outpaced by China, which is quickly advancing in navy clear power innovation. Operational prices will rise as fossil gas costs fluctuate and provide chains turn out to be extra fragile, making European forces more and more weak to power shocks. Even its personal deterrence capabilities may weaken, as outdated power infrastructures fail to maintain tempo with the evolving calls for of recent warfare.
The selection is evident: Europe can lead the way forward for protection by embracing a fossil-free navy—or threat falling behind within the new period of safety and energy.
When Militaries Fail to Spend money on Inexperienced Innovation
Europe is at a crossroads: it may embrace navy clear tech—or double down on outdated techniques. Sadly, current protection procurements counsel that some nations are nonetheless caught up to now.
Regardless of the clear strategic and financial advantages of a fossil-free navy, many protection procurements proceed to lock in outdated expertise. A putting instance is Sweden’s current €1.4 billion procurement of 775 military trucks. As a substitute of investing in fashionable, lower-emission alternate options, all autos had been ordered with diesel engines based mostly on the Euro III emissions commonplace—a regulation that’s 25 years previous and has been changed a number of occasions. These vehicles will stay in service for many years, additional entrenching fossil gas dependency in Sweden’s navy infrastructure. The reasoning? A perceived want for ‘upkeep simplicity’ and avoiding reliance on fashionable emissions-control applied sciences like AdBlue. But whereas Sweden locks itself into fossil gas dependence, different militaries are proving that hybrid and electrical alternate options are already combat-ready and operationally efficient.
This failure to modernize isn’t just an environmental problem—it’s a missed alternative for strategic management. Whereas China and different world powers make investments closely in inexperienced navy expertise, Europe dangers falling behind by making procurement selections based mostly on outdated assumptions fairly than future safety wants.
The query is not if militaries should decarbonize—however whether or not Europe will lead or be pressured to observe
With €800 billion in navy investments deliberate, the EU faces a decisive second: lock in fossil gas dependence or form the subsequent technology of world safety.
To prioritize safety, Europe should mandate inexperienced procurement in its protection finances, speed up military-to-civilian tech transfers, and foster public-private cleantech partnerships—steps that overcome oil trade resistance to make sure power independence and management. No navy can defend towards local weather collapse, however innovation and funding can. The window is narrowing—Europe’s future is determined by performing now.
