It sounds terrible . What will happend in the future?! The research doesn't differentiate between seasons , and every one knows how polluted the air is in the winter when everyone is heating their home and apartament.
Power plants are usually not placed inside cities. Less gasoline cars inside cities will definitely improve the local situation, not just limited to CO2.
Nuclear power is a good option, wind and solar are usable for charging batteries - either EV batteries or storage banks which can be used to charge EV batteries. The problem with wind and solar is that there is no long-term storage solution as of yet but single-day storage is already achievable. Once enough nuclear capacity has been built up I foresee wind turbines disappearing from the landscape since they are cumbersome bird-killing eyesores. Solar power is there to stay since buildings need roofing anyway and we'll soon be at a point where the price difference between 'passive' roof cladding and PV 'panels' is close to negligible so it makes sense to install PV roof cladding and get some power for free, especially in places where air conditioning is popular.
EVs generate far, far less brake pad dust, most of their braking is regeneration via the motors.
Tires get more efficient every year, dust has reduced as the companies compete to make them last longer, and we're finally seeing the tire industry respond to pressure to reduce toxic runoff. Michelin's been removing phenols, for instance: https://resicare.michelin.com/news/michelin-resicare-resin-1...
One more reason to look to an electrically heated future. Where I live the air becomes unpleasant in winter as some neighbours heat their homes by burning what i can only assume are old tires and horse carcasses.
I remember as a kid visiting the home of a relative who had an old oven for wood/coal heating, even though the primary heating was now a gas (natural gas not gasoline) heater.
The old oven remained though, and was used as a self-emptying trash can. When it filled up, a fire was lit to empty it. I don't remember what the sorting rules were (I assume "does it burn well and not smell up the apartment too badly when lighting it") and how common plastic packaging was back then, but I'm sure that the emissions coming out from the chimney were not a concern.
