The climate costs of war and militaries can no longer be ignored.  More than 5% of global emissions are linked to conflict or militaries but countries continue to hide the true scale. Guardian Doug Weir 9 Jan 2024 In early 2022, journalists began to ask us how Russia’s full-scale invasion of Ukraine was affecting the climate crisis. While we could point to landscape fires, burning oil refineries and the thirst of diesel-hungry military vehicles, the emissions data they sought just wasn’t available. When it came to the reverberating consequences of Russia’s manipulation of Europe’s fossil fuel insecurity, or to the weakening of the international cooperation necessary for coordinated global climate action, our guesses were no better than theirs.

Two decades of international analysis and debate over the relationship between climate change and security has focused on how our rapidly destabilising climate could undermine the security of states. But it has largely ignored how national security choices, such as military spending or warfighting, can have an impact on the climate, and so undermine our collective security. With climate breakdown under way and accelerating, it is imperative that we are able to understand and minimise the emissions from all societal activities, whether in peacetime or at war. But when it comes to military or conflict emissions, this remains a distant goal.

Russia’s war in Ukraine has seen the first attempt to comprehensively document the emissions from any conflict, and researchers have had to develop their methodologies from scratch. Their latest estimate puts the total as equivalent to the annual emissions of a country like Belgium. Ukraine is not a one-off, with a similar clamour for emissions data around Israel’s war against Hamas. While the devastating ongoing conflicts in Sudan or Myanmar are yet to see attention on their emissions, the trend is clear: the carbon cost of conflict needs to be understood, just as the humanitarian, economic or wider environmental costs do. A proportion of those carbon costs come from military activities. For these, understanding is hampered by the longstanding culture of domestic environmental exceptionalism enjoyed by militaries, and how at the US’s insistence, this was translated into UN climate agreements. An exclusion to the 1997 Kyoto protocol became voluntary reporting under the 2015 Paris agreement. But when we began to collate and publish the emissions data that militaries report to the UNFCCC (United Nations Framework Convention on Climate Change), we found that only a handful of countries publish even the bare minimum required by UN reporting guidelines. Many countries with large militaries publish nothing at all......read on     https://www.theguardian.com/commentisfree/2024/jan/09/emission-from-war-military-gaza-ukraine-climate-change
