International Affairs | Low-carbon warfare: climate change, net zero and military operations

16.02.23
Defence has a carbon problem. This article introduces the concept of ‘low-carbon warfare’ as a means of capturing recent developments, the extent to which they dovetail with existing concerns regarding the business of war in the twenty-first century, and the prospect of significant changes to how militaries operate in the years ahead as the global energy transition unfolds.

Nature | Decarbonize the military — mandate emissions reporting

01.12.22
This article in Nature outlines the state of military emissions reporting so far and presents a way forward for academia and civil society to combat the problem.

Pentagon fuel use, climate change and the costs of war

01.09.19
Neta Crawford explores the U.S. military’s contribution to climate change. She finds that although the Defense Department has significantly reduced its fossil fuel consumption since the early 2000s, it remains the world’s single largest consumer of oil – and as a result, one of the world’s top greenhouse gas emitters.

CEOBS | The COP where we began talking about conflict emissions

20.12.22
A month on from COP27, Ellie Kinney reflects on her time in Sharm El-Sheikh. Ellie landed at the COP with our newly published policy brief, and with a mission to advocate for better reporting of military greenhouse gas emissions.

CEOBS | Climate trackers: join us in shining the spotlight on militaries

02.09.22
Pressure from campaigners, researchers and journalists has been instrumental in driving climate action by states and large corporations. Climate action tracking websites and reports play a vital role in informing this process but as Ellie Kinney writes, the leading climate tracking sites are silent on military emissions.

CEOBS | NATO won’t say how it will count its carbon emissions

30.06.22
NATO has pledged to reduce its instituational emissions but won't publish the methodology it will use to count them. Doug Weir argues that this lack of transparency underscores the importance of military emissions instead being addressed by the UNFCCC.

MEG Conference 2023 | Panel 4: Military carbon footprints: how do we decarbonise?

01.11.23
Decarbonising the military will require a combination of mitigation solutions, including developing and adopting new technologies, use of nature-based solutions across the military estate, education, behavioural change and even rethinking military strategy. This panel will discuss the broad and diverse range of possible mitigation actions, and the challenges of implementing them.

MEG Conference 2023 | Panel 3: Understanding wartime emissions: lessons from Ukraine

01.11.23
Russia’s war in Ukraine has contributed to unprecedented interest in the emissions footprint of armed conflicts, encouraging novel efforts to comprehensively estimate its emissions. Emissions from the war zone, and its impact on emissions elsewhere were estimated for the first 12 months of war. This panel will discuss the initial results, and the numerous challenges in determining impact emissions sources,…

MEG Conference 2023 | Panel 2: From bases to bombers: assessing the military’s organisational emissions
