The EU Commission continues its battle with Poland over air pollution. The air in Poland makes up 33 of the 50 worst urban areas in the EU. Emissions from coal plants, old cars, and household burning are the culprits.
Changing things will require a lot more than electric cars now being encouraged, since they remain charged by coal fired power plants and actually increase emissions.
I don't think that it really any plan in Poland to do anything different. If there is, it is not clearly in public right now and certainly will not be dramatic enough to work any time soon.
