>road transport (trucks)>shipping>aviation>iron and steel production>cement>plastics productionTransportation is seeing billion of dollars invested into research to fix this problem. Battery powered electric trucks are not as easy as small vehicles, but there is plenty of effort to fix this problem. In the EU, pilot programs to electrify roads with overhead lines that will power trucks are being tested. (the answer is actually to use trains but whatever)
There are designs for hydrogen powered ships. Actually building something and testing it at scale will not happen quickly. The storage facilities for hydrogen would also need to be built along major shipping routes and the technology to make green hydrogen (not from methane) has to mature and be rolled out. I've seen estimates that by 2050 green hydrogen fuel will be cheaper than just burning fossil fuels. Any change that happens in this direction will be comparatively slow.
Airbus is also designing a hydrogen powered plane. I don't know enough about this to comment. I'm skeptical that aviation can replace fossil fuels, since alternative fuel sources are generally not as energy dense and weight is the deciding factor. Maybe for short flights it will have a purpose.
The best way to reduce emissions from production of plastic is to stop fucking using plastic for everything.
The concrete industry is exploring efficiency upgrades and carbon capture tech at the plants. Ultimately, decarbonizing the concrete industry is impossible, but optimization and cutting out unnecessary emissions is the current goal. Similarly for the steel and iron industries.
