@silence7 I don’t think there will be anything more than a rough estimate for the militaries, given that many are developing secret projects, or have their number of various vehicles classified.

But war, sadly, ads a lot to greenhouse gas emissions. Literally every single vehicle could at some point be set ablaze, and it doesn’t matter how much that vehicle emits. It will just burn to the ground and all these rubber and plastic components will go in the atmosphere.

Also, explosions can set everything ablaze, not just vehicles. And it’s also the modified terrain after the explosions, forests destroyed and if we also happen to bring nuclear weapons in the field, it’s game over for the planet.
