In general, in all countries where the number of cars with internal combustion engines exceeds the threshold of 25 per 100 people, air quality drops sharply in any area where there is dense construction and a concentration of people inefficiently using private transport, but on the whole the air on the planet was cleaner. With the advent of electric cars, it will a priori become dirtier everywhere, and it will be decades before the overall level of environmental improvement becomes lower than when using a car with an internal combustion engine.
This is the key problem - selfish city dwellers in "developed" countries, who suffer from poor ecology and smog in cities and suburbs due to hundreds of millions of cars with internal combustion engines, for the sake of improving the local ecology, are ready to sacrifice worse air for everyone for decades (because for city residents, the air will become many times cleaner, but not for rural residents!), without the consent of residents living outside cities and suburbs, whose air was cleaner, but will now obviously become dirtier with the massive spread of electric cars, therefore the overall impact on the ecology of the industry in general, it will increase until technology improves several times and the impact of battery production and distribution of electrical energy decreases, its accumulation is several times the current technological capabilities.
And again the rich (more like pseudo-rich, until someone finally shouts that kings are naked) dictate the agenda to the residents of third countries (even supposedly "independent" Russia agreed to pay a tax on "environmental damage", which in itself is nonsense, which, obviously, goes in favor of the "developed" countries and strengthens their dominance) of the day, and with deliberate damage to the latter.
