It may be some time before sustainable aviation fuel plays a role in reducing military aviation emissions, all the more reason for ensuring comprehensive and transparent military emissions reporting now. bsky.app/profile/ryan...

The populist and extreme right would love military sustainability, and environmental and climate security discourse, to be a culture war issue. It's quite important that they are called out on this, at least on the platforms populated by humans.

Some say the UK Ministry of Defence "is too large and complex an organisation for net zero targets, and it must prioritise its mission." Anyway, here's the NHS's latest report on its decarbonisation journey: www.kingsfund.org.uk/insight-and-...

Any politicians who believe investment in green energy is not an investment in security are frankly deluded. www.bbc.co.uk/news/article...

PhD Studentship in War and Climate Change: University of Reading, UK. This looks like a great opportunity for someone wishing to study the military's contribution to the climate crisis: www.jobs.ac.uk/job/DPU288/p...

While the International Criminal Court's new environmental policy guidance considers the atmosphere part of the "natural environment" this explicit mention of atmospheric damage in relation to the crime of aggression is of particular relevance for conflict GHG emissions.

As #Ukraine announced that it will seek climate damage reparations from Russia, we spoke to Time about the climatic and wider environmental impact of war time.com/7335449/ukra...

“We have to prioritise #ClimateAction even in a time marked by war and conflict.” Well done #Denmark. www.euronews.com/green/2025/1...

New report reveals even the most transparent nations are only reporting a tiny fraction of their true military carbon footprint... www.sgr.org.uk/publications... 🧪

If armed forces were a country, they’d be the 4th-largest emitter.

At COP30, Ukraine’s Ministry of Economy, Environment & Agriculture has announced a $43 billion claim from Russia for the climate damage caused by the invasion, based on conflict emissions calculations by the Initiative on GHG Accounting of War.

At COP30, military emissions continue to be left off the UNFCCC agenda. Through our side event, we were proud to address the intersection between climate, conflict and militaries directly, alongside @qmul.bsky.social, @sipri.org, @ecodiya.bsky.social, HI, and the Initiative on GHG Accounting on War.

New #COP30 @thewaronclimate.bsky.social policy brief exploring the #UNFCCC’s military emissions reporting blind spot, how rising military spending is exacerbating the problem and what needs to be done to address it: ceobs.org/briefing-acc... Recommendations🧵1/4

As #COP30 kicks off in Belém, here’s where you can find @ceobs.org and friends across the next two weeks:

Les armées du monde entier alertent sur la nécessité urgente de se réarmer, alors que le dérèglement climatique devient une menace majeure pour la sécurité, même si leurs propres émissions de carbone continuent d'augmenter. www.bbc.com/afrique/arti... #COP30

Wars affecting every corner of the globe, military spending at a record high, and 1.5 degrees breached. Our #COP30 preview wonders what, if anything, will be delivered on conflict, climate and militarism. ceobs.org/cop30-what-t...

#Military spending and GHG emissions are rising but reporting is getting worse. Our new analysis finds that the the top three military spenders are either no longer reporting emissions to the #UNFCCC (US and China), or the data is useless (Russia): ceobs.org/new-data-rev... #COP30

It's #EnvConflictDay; we're making progress but the challenges are huge. More people are aware and care than ever before but the rules that are supposed to protect the environment in war are broken daily, and it's people and ecosystems paying the cost.

Our new analysis finds that military spending and GHG emissions are rising but national emissions reporting to the #UNFCCC is getting worse. Some major military spenders have stopped reporting, including the US, Russia and China. ceobs.org/new-data-rev... #COP30

A welcome #COP30 preview on military and conflict emissions. NATO declined to comment for it, a rather different tone than in the Stoltenburg era... www.spglobal.com/commodity-in...

Failing to count the GHG emissions from conflicts "underreports and distorts our understanding of global warming and undermines the ability of the international community to tackle its causes." theconversation.com/how-wars-rav...

In a new post on @ceobs.org, Usman Ali explains how South Asia is being hard hit by the #ClimateCrisis but #India and #Pakistan's security postures are diverting money from adaptation and contributing to emissions: ceobs.org/militarisati...

Militaries are betting on SAF as a bridging fuel. A new @carbontracker.bsky.social report finds that even if all existing, under development and announced projects operate at full capacity, production would only supply around 5% of global jet fuel demand by 2030 carbontracker.org/sustainable-...

Rheinmetall's proposed Giga PtX project aims to establish a Europe-wide network of several hundred modular e-fuel production plants; capable of producing 5-7,000 tonnes of military use diesel, marine diesel, or kerosene/facility/year. www.rheinmetall.com/en/media/new...

Did you ever wonder why politicians and militaries talk up the use of small modular reactors? Military dependence on civil #nuclear industries is a key factor. theconversation.com/the-hidden-m...

ICYMI last week retired senior military personnel call for spending renewable energy to be counted as defence expenditure under the NATO GDP spending pledges. www.theguardian.com/environment/...

New paper suggests that the GHG emissions for a decade of reconstruction in #Ukraine would be 741 Mt CO2, 4x Ukraine’s pre-war annual territorial emissions. iopscience.iop.org/article/10.1...

Whether they like it or not, militaries face a future of low carbon warfare, and without change, they risk being locked into outdated technologies even as global energy systems shift, argues @duncandepledge.bsky.social. 🦕 www.lboro.ac.uk/news-events/...

#EU green transition and defence policies are at times contradictory, e.g. exempting military spending from the “do no significant climate harm” principle. This @ecfr.eu report instead argues that the two areas can be mutually reinforcing ecfr.eu/publication/...

The climate crisis is increasing the risk from wildfires on military training ranges, even as increased military spending may increase training intensity and militaries explore the potential of lands to sequester carbon, offsetting their emissions 1/2 www.stripes.com/theaters/asi...

How's your autumn going? Intense? Us too. It's always our busiest time of the year thanks to all the international events that take place. They are amazing opportunities to speak up on conflict and the environment but it's A LOT. Right now we're two down, five to go. 👇

Exciting to see this new project launching today, when the question of what genuine security looks like has never been more important. Be sure to follow @transitionsec.bsky.social and find out more in their launch essay: jacobin.com/2025/10/milita…

How has 3 years of Russia’s invasion of Ukraine impacted emissions? The latest report from IGGAW escalates the climate damage of the war to over £43bn, with emissions matching the annual outputs of Austria, Hungary, Czech Republic and Slovakia combined. en.ecoaction.org.ua/climate-dama...

Our #IUCNcongress briefing examines the intersection between militaries, armed conflicts, nature and the climate crisis. It's a critical time for IUCN to consider how it can advance dialogue on this. ceobs.org/briefing-mil... 1/2

Countries in Europe's east are looking to peat bogs for military defence; #Latvia's MoD is now a fan of rewetting and #peat restoration. So far the talk has only been about security, surely we'll soon hear that these projects offset military emissions too? www.mod.gov.lv/lv/zinas/nac...

Today we're briefing the Irish Senate on the climate implications of the #ReArmEurope Plan/Readiness 2030, in our view the plan is inconsistent with Europe's #NetZero targets: www.oireachtas.ie/en/press-cen...

On Wednesday we're giving evidence to the Irish Senate's Joint Committee on Finance on the climate implications of proposed increases in EU #military spending. EU progress on military decarbonisation and emissions reporting is being sidelined in the rush to rearm.

Africa needs $70 bn/year for climate adaptation; in 2023 it received just $14.8 bn, now at risk of falling as donors cut aid. Meanwhile world #military expenditure reached $2.7 tn in 2024, rising by 9.4% from 2023. www.context.news/climate-just...

An important new report from @responsiblesci.bsky.social published today finds that a $100bn rise in military spending adds ~32 million tonnes of planet-warming gases to the atmosphere. Found out more ⬇️

Great to see @theconversation.com running a War on Climate series. Their third post looks at the potential role of sustainable aviation fuels in military decarbonisation. Last week a study in Nature suggested a hard limit of 50% life cycle emission reductions theconversation.com/sustainable-...

“The greatest risk is not necessarily the territorial threat of a neighbouring country’s army ... it is cyberterrorism; the next pandemic for which we are not prepared; and most certainly the domino effect of runaway climate change.” www.theguardian.com/environment/...

A new analysis of the climate impact of sustainable aviation fuel finds that its maximum benefit over fossil jet fuel is ~50%. Military aviation is one of the primary sources of military GHG emissions and this study should come as a reality check. www.nature.com/articles/s41...

EU countries are about to spend billions more on military equipment, they have an opportunity to shift towards a lower carbon pathway, will they take it? illuminem.com/illuminemvoi...

This accessible overview by Duncan Depledge explores how war exacerbates #ClimateChange; why climate change demands military responses; and how armed forces will need to adapt: theconversation.com/three-reason...

In a world transitioning to clean energy, and where the #ClimateCrisis has been recognised as a threat to national security for decades, this is a heroically dumb take thehill.com/opinion/ener...

Wildfires on firing ranges can be a significant source of peacetime military GHG emissions, the scale of emissions is often increased because the presence of UXOs makes the fires too difficult to fight, meaning they are left to burn out.

Interest in rewetting eastern Europe's peatlands as a defensive measure against Russian invasion continues to rumble on, apparently inspired by the flooding of the Irpin valley in #Ukraine. Some thoughts... 1/5 www.politico.eu/article/russ...

In the 'biggest case in human history', the International Court of Justice has outlined the legal responsibility of States to address climate change. In our latest blog, @aradami.bsky.social explains what the outcome means for military and conflict emissions. ceobs.org/what-the-icj...
