IPCC's 6th Assessment Report was published in much fanfare back in August 2021. In the ever heated conversation about the climate emergency, Net Zero and the future of the planet, and the zealous act of singling out the culprits of CO2 emissions, the IOCs (International Oil & Gas Companies), regulated utilities, automobile manufacturers, steel and building materials and civilian airlines are the usual suspects. And yet one industry and the biggest emitter in the world is nowhere to be seen and absent from the carbon trackers of U.N, IPCC, WMO, US EPA or IEA for that matter. The armed forces and defence sector are the single biggest contributors to CO2 emissions of the planet.
