Might not be that bad for the environment but holy hell does it turn air quality to shit the next day.

I am not sure whether you talk about those fireworks for few minutes/hours or these quite common rocket explosions + EV fires...

Personally I don't even own a car, so don't go on me with some carbon emissions and polluting enviroment, 95% of year I use public transport (most of the time electric trams), only 1-2 a year a ride a car when visiting mother/father.
