Preventing wars, demilitarisation and promoting peace are vital strategies for tackling climate change, writes Dr Sue Wareham OAM, President of the Medical Association for Prevention of War. She also urges the Defence Department to lift its game on climate action, and to commit to improved measurement, reporting and scrutiny of military emissions.

It is encouraging and long overdue that the preservation of health is now recognised as a key reason for urgent climate action. All those who have worked hard to achieve this result should feel very proud.

Theconsultation paperwhich was released recently for Australias first National Health and Climate Strategy rightly also recognises health equity as one of the important guiding principles.

However, there is one glaring inequity in climate strategies globally that continues to be overlooked. It is the virtual blind eye turned toward military greenhouse gas (GHG) emissions, while health and other civilian sectors attempt the hard yards of reducing their emissions.

Consider the climate impacts of wars and their preparation.

It is estimated that the worlds militariesmay be contributing 5.5 percent of global GHG emissions a percentage so significant that it cannot be ignored.

If the worlds militaries were a country, it would have the fourth highest carbon footprint (after China, the USA and India). As just one example of wars intense thirst for fuel,one B52 fighter jetconsumes about as much fuel in one hour as the average car driver uses in seven years.

The richest countries are spending30 times as much on their armed forcesas they spend on providing climate finance for the worlds most vulnerable countries. This is inequity on a grand scale. Notions of security and threat have been hijacked by militaries to justify wars and threats of wars that destroy prospects of genuine security for all on a sustainable planet.

War and its preparation also createnew and significant sources of GHG emissions, including huge transport operations, the destruction of vegetation, and the need for reconstruction of destroyed infrastructure.

Climate and other environmental concerns are deprioritised when nations are at war, and cooperation between nations ends. As of early 2021, seven countries were yet to ratify the Paris Agreement, and five of the seven were or had recently been involved in a conflict: South Sudan, Iraq, Eritrea, Yemen and Libya (seehere).

Defence lacking

In Australia, where military activity is rapidly increasing, the Defence Department is paying grossly inadequate attention to climate change.

The Australian Security Leaders Climate Group commented on the unclassified version of the recent Defence Strategic Review, stating that it largely ignores the significance of climate risk. The group stated their impression that the review regards climate change as a one paragraph concern, which should not be allowed to interfere with the far more serious business of military mobilisation in preparation for WW3.

The Australian Defence Force says it has initiated a range of investments to drive GHG reductions, but there is no information about the level of current ADF emissions, how they are measured, or how it deals with operational emissions.

In the period 2001-2012, the Defence Department was responsible for_66 percent_of total Australian Government emissions. In the same period (2001-12) the Department of Health and Ageing was responsible for_less than one percent_of public sector emissions.

Since 2012, no emissions data from the Defence Department has been made public, and reporting on energy use has been incomplete. It does not take into account military supply chains, a source of considerable embedded carbon emissions given the hardware needed to fight wars. Therefore, Defences contribution to national emissions is likely to be much higher, and to have increased proportionately since 2012.

Internationally, the reporting of military emissions is voluntary rather than mandatory, and it is most often not done. At the 1997 Kyoto negotiations, final-hour demands made by the United States led to the exemption of such emissions from climate negotiations and from emissions reduction targets, creating a significant emissions gap.

There are moves in civil society to change this, such as from theConflict and Environment Observatoryin the UK. In Australia, the Medical Association for Prevention of War is joining these efforts and advocating some steps that Australia must take to make climate action, and the National Health and Climate Strategy, genuine whole-of-government matters.

Australia should take the following steps:

• Commit to improved measurement, reporting, and scrutiny of military emissions
• Include military emissions from all sources and supply chains in overall calculations of Australias emissions, and mandate a reduction target that reflects the urgency of the problem
• Work with other states to ensure that military emissions are on the table at the COP28 meeting in December this year.

Work for peace

To achieve the necessary GHG emissions reductions, both in Australia and globally, we must reduce military activity.

As just one part of this, we must reverse the current trajectory towards a further major war, between the US and China, which would be a disaster for the climate quite apart from its other multiple impacts. Talk of war distracts attention and funding from where it is really needed, which is in global cooperation to address our common threats.

Demilitarisation is a highly effective means of decarbonisation. A green militaryis a fantasy, but one that many militaries including our own will probablytry to pursue at our expense.

Only a peaceful planet can be healthy and sustainable.
