Even places like Dubai and qatar there will be air pollution and not only becouse of oil the heavy raining but now the war Will couse Also not balanced climate.
There is large establishment of emirates in London UK so the wealthy ones can go there while war is in middle East.
Btw....the air will become bad there it's not healthy you pay some huge money for Dubai Luxury but you can't breethe clean air ..only way will be stay indoors with filtered air.
As for researching, there are only two countries that are zero carbon dioxide emission countries. They're named by this source:
https://net0.com/blog/net-zero-countriesThese countries aren't being heard a lot but I think Suriname has been named by a netflix movie that's quite bad so, the government became made onto that movie but I forgot the name of it. As for Bhutan, it seems a peaceful country but getting visa or entering the country there is quite expensive, tricky and hard. While with the progressive countries, those that have a lot of rich people, expect that air pollution will continue to add more until the government starts to be strict with it.
And seemingly with the rumors of war in those regions, those ballistic missiles, rockets, fire arms and all other weapons that will release some gases and smoke, they'll add more to it. It is a meme that I see that people breathe air through cans, I hope that we don't get onto that reality someday and we can still breathe clean air on our areas.
