The only subtle detailed you missed, which is not surprise, is that Sweden and Norway (not sure which if the other skandies, maybe this is a EU thing, hm) use those letters, with those colors, and those arrows to indicate energy efficiency rating. So, it could be a nudge at the relationship between reducing emissions or suffer consequences of global warming, which will eventually lead to famine and war.
