I gave up after ten minutes of being assaulted by ugly cars.

It would have to be sails though as the "bunker fuel" used by big ships is very polluting

Still a ship with several 1000 passangers plus some cargo is no where near as polluting as a plane running on heavy fuel or not.

A liner is a very different ship to a cruise ship, there are none left we would need to build new ones meaning they would have the most efficent engines etc a 2 stroke marine diesel engine with waste heat recovery and shaft generator is approaching 70% efficency or it is on cargo ships. Rotor sails and solar pannels could also be fitted to reduce power generation needs as with a passanger ship unlike a container ship it has a fixed exposed surface instead of an ever changing one. Liners generally have a decent cargo capacity on top of passanger capacity. I work in the marine industry for a container company and we have a stellar environmental record admitidally the cruise ship industry dosent but that is down to bad oversight of them by the governing bodies. If all the rules were obeyed and adheard to it would be far and away less polluting. Plus the govening bodies dont make the punishments strict enough.

Yes i agree with most of that and more needs to be done and is, in 2020 there is going to be a world wide cap on sulphur emissions from ships reducing the content in fuel from 3% to 0.5% or lower in europe there is already a 0.001% cap on fuel sulphur and has been for more than 10 years, and even china and america are now that low too. Ship scrappage is an area which really needs worked on admitadly. But he dose neglect the fact that 90% of the worlds freight is carried by sea. http://www.ics-shipping.org/shipping-facts/shipping-and-world-trade

I don’t think it’s been neglected, the report just highlights that shipping isn’t quite the green utopia you seem to have been lead to believe. For sure it has the possibility to become greener than carting people about by planes but the fact is, currently it doesn’t seem to be, when you compare like for like (ie passengers)
Obviously for freight then shippping is the first choice but for passengers it’s not quite as clear cut as you make out.

A big issue to get over is the time difference too, fly across the Atlantic in 8 hours, how long would you be looking for a crossing by ship? Travel to landlocked countries? It feels like it would be a major step back in time and I reckon there'll be some version of environmentally friendly aircraft before travelling by ship becomes the norm again.

For short haul diesel IC prop planes which could then have emission controls were suggested as being more suited for flying within countries leaving the higher flying jets for long haul.

That was a brilliant send-up. Been out for ages now though.

So just for fun I've recorded my driving habits this week
500 miles, good mix of roads including 160 miles of motorway (Friday)
Started with half a tank of diesel, filled up Wednesday (£108, 5 minutes) and I've just under half a tank left now
I didn't have to plan any journey based on distance or charging points
When I can buy an electric car for £4k that can do that while carrying 800kg of stuff I will buy one
This was a fairly typical week for me, I also never made the same journey twice
