It's not up to individuals to fix it. Your impact is nothing.
Cars matter very little in the big picture as well -- it's a distraction to blame the little people.
The vast majority of pollution is caused by industrial processes. The fix here is simple: regulate and enforce the regulation.
The main polluting countries are:
the USA: too afraid to do anything in case it affects their economy, political caste too corrupt to do what's needed.
Russia: doesn't give a shit, mostly see global warming as a way to get more influence, more usable land, and have such a little population density anyway they can afford to fuck some of it.
India: polluting as a result of too many people and trying to catch up economically, but might get their shit together like China did.
Saudi Arabia: has built their whole state on an unsustainable dependency on burning more than half of the oil they extract just for AC and water, and is completely fucked regardless.
We don't care about pollution, for climate change only the pollution of carbon dioxide matters. The majority of carbon dioxide is produced by transportation and heating, much of that from individuals.
There are a lot of people that want to deflect from action on climate change by focusing on the oil refinery and not the tailpipe.
Your list is suspiciously missing China, the biggest producer of CO2. Saudi Arabia is down the list, after South Korea and Germany; their CO2 per capita is but not abormally. It is the per capita emissions and population that matter. Then USA (300 million), Russia (147 million), Saudi Arabia (40 million), India (1.4 billion). The first three have large per capita emissions, double the others. The list of CO2 producers are basically a list of large and/or rich countries.
World society is just a bunch of individuals so some have to do something.
Re global regulation you need to get the main players like the US, China and Russia to agree some sort of policy which is tricky but might be possible if people lobby their politicians.
There is already a global agreement that the US keeps getting out of.
China has already solved their problem and significantly improved air quality in its cities, and is the world biggest builder of nuclear power plants. They ceased being a problem already.
