Another fun fact - any developed country X (and you cant get much more developed than Switzerland currently globally, when ignoring some tax haven micronations) emits more bad ABCD than developing country Y having population N-times greater than population of X.

What you say is true, but useless on its own. Whole world knows that, its perfectly logical, but thats about it.

It's definitely not the case that the whole world knows that. I have recently been told by someone that European green policies are useless and manipulative since there are 7 billion other people in the world who pollute. The notion that not everyone pollutes the same never crossed their mind.
