To be of any use at all, a solution needs to be affordable, acceptable and effective.
I haven't seen any thing that fits all those criteria, which means it's probably not going to happen.
For instance, stopping all non essential flights would remove a lot of pollution from the atmosphere, but will it happen- no way.
Banning private cars in cities would help, but is it going to happen- not a chance.
BTW electric cars are polluting to make, to get rid of and might use polluting methods of power generation to charge them.
Unless we return to sailing ships, all those freighters on the ocean are hugely polluting.
There is no reason not to use modern technology sailing ships, but is that going to happen- LOL.
Anyway, so long as the world's human population continues out of control, nothing, IMO, is going to make any difference whatsoever. Just look at all those people from <deleted> countries that are risking their lives to get to western countries where they can become consumers and drive cars etc.
