#Military emissions make a significant contribution to #ClimateChange, our new blog explores why this is and what needs to change. A lack of transparency means we don't know how large their contribution is but we do have some stats⬇️ ceobs.org/the-militarys-…#ClimateAction 1/6
Global military expenditure rose to almost US$2 trillion in 2020, this is important for military emissions because a large proportion are indirect and come through supply chains and lifecycle costs. Here's a chart. It's really not all about emissions from engines. 2/6
Which isn't to say that engines don't matter. As of 2021 the global #military aircraft fleet is 53,563, which is double the projected civilian fleet (23,715). But because the military don't report where they fly and how much fuel they use we don't know what it contributes. 3/6
Military training areas cover between 1-6% of the global land surface. This means that if militaries improved their land management practices they could optimise carbon sequestration and minimise carbon losses from soil. This means not setting fire to ranges. 4/6
Until they start tracking and being open about their emissions, it's going to be difficult for the military to do anything to reduce them. This would be helped enormously by setting some specific, timebound emissions reductions targets, say at #COP26. ceobs.org/governments-mu… 5/6
Anyway, there are lots more stats and perspectives on the sources and scale of military emissions in the blog, as well as on the many gaps in the data. We really need to keep building momentum on this issue if we want anything to be done about it ceobs.org/the-militarys-… 6/6

In focusing on the security risks of #ClimateChange have we neglected to ask how conflicts affect emissions? Our new overview explores how the environmental and social changes that occur in war influence emissions, and why we need to track them ceobs.org/how-does-war-c… 🔽 1/7
The direct emissions in conflict are the most obvious, for example attacks on oil infrastructure, or scorched earth policies. But we also see significant changes to land use that have a major bearing on whether areas store or release carbon. 2/7
Peace can also generate emissions, we almost always see spikes in deforestation, and we need to factor in the emissions costs of managing conflict debris and of reconstruction. Conflicts impede environmental governance, which also has a bearing on emissions. 3/7 #EWIPA
