They emit a lot, but they transport … a very lot. Trucks are higher emitters per comodity.
Still both should be powered by something else like hydrogen (more interesting for ships I guess) or batteries…
And cruise ships should be IMHO taxed so high (the tax should probably directly go to countermeasures), such that only very rich people are able to (not that I grant them the fun, but they should finance this climate disaster in every possible way…)
Shipping? Shipping is about 2 % of global CO2 emissions.
Large ships emit a lot of sulphur oxides (SOx). E.g. cruise ships emit more than all cars of Europe. SOx is not a greenhouse gas, but it’s a nasty pollutant nonetheless.
