I don't follow what you're saying. Is it that other emissions than CO2 are more important to fight? Well, that change is already happening with the ongoing big change towards LNG as the preferred fuel for shipping. But when it comes to reducing CO2 emissions, outside of improving energy efficiency, it seems nobody has anything even remotely viable today. That goes both for deep sea shipping and for most air travel.

There's always sailing, although it's a bit laborious, and fission has a good record at sea :-)

  There is some progress in applying wind power to shipping (other than the traditional fixed sails) - https://www.ship-technology.com/projects/msbelugaskysails/ https://www.ship-technology.com/projects/msbelugaskysails/ The German company SkySails has been working for years on kites that can reduce fuel use on large ships. I think at some point we'll see alternative (renewable) energy taking over shipping as it is gradually taking over other domains.
