To be clear, those three categories combined probably represent (spitball) less than 7% of total global emissions. We have a pretty clear path towards eliminating 80%+ of overall emissions, and that would buy us some time to figure out solutions for the remaining 20%.

But since you asked:

1- Freight trucks, for now, will likely be either carbon capture, or a clever EV retrofit like SixWheel. Batteries probably aren’t quite there (in 2022) to go full EV for all applications but the learning curve slope is such that that could conceivably be only 5 years away.

2- Aircraft are most certainly going to be SAF eg a green/renewable fuel until battery tech improves by an order of magnitude (10-20 years?)

3- Similar story for sea vessels on the batteries front, though for those CCS is likely to be the most promising interim solution.

For all of the categories you mentioned there are relatively promising 10-30 year prospects for full electrification and much more short term prospects for emissions mitigation. And these are part of the hardest 20% of emissions.

Long story short the situation is not nearly as bleak as you make it out to be.

This is a problem that is going to take care of itself. World population is peaking and there's nothing that will get the world back to replacement fertility (2.1 children per woman) in the near term. As the world takes its long gentle slide into depopulation, carbon emissions will taper off. Problem solved.
