This is just insane. Not only are cars themself mostly unnecessary, if the right infrastructure is provided, but SUVs also use more resources to run and be produced then small cars, without any advantage over them. So an obvious waste, which could easily be cut to reduce emissions.

That would be my uneducated guess as well. Taking everything like processing, shipping, storing, growing the feed and all it requires into account for meat production, I would be shocked if it weren't higher than passenger vehicles combined.
