Roman Abramovich’s yachts are said to emit more carbon than many small countries. This is unsustainable, and wrong
“The rich gazed at their superyachts, and decided they were not enough. The new breed of megayachts, which are at least 70 metres (230ft) in length, may be the most expensive moveable assets ever created.”
“First and foremost, owning a megayacht is the most polluting activity a single person can possibly engage in. Abramovich’s yachts emit more than 22,000 tonnes of carbon every year, which is more than some small countries. Even flying long-haul every day of the year, or air-conditioning a sprawling palace, would not get close to those emissions levels.
The bulk of these emissions happen whether or not a yacht actually travels anywhere. Simply owning one – or indeed building one – is an act of enormous climate vandalism.”
I just asked because you said it was hard work on a 2 person vessel. I don’t sail so I was just wondering why that would be. Is it labor intensive with moving the sails, or more mentally fatiguing to constantly calculate where to position sails? I’ve not so seriously considered crossing the Altantic (which I heard requires a year of preparation). So to the question as to whether an automated sailboat for two would be greener, I would say /yes/ to the extent that it might encourage more people to sail.
Cruise ships aren't all that much worse than long haul flights (specifics gonna depend on the ship and the plane but my first google results ended up with a 14 day cruise being roughly equivalent to four transatlantic flights) purely in terms of co2, just bc there are so many people on board. Though flights also need to cut emissions by a lot really, so that's still not great. And cruise ships tend to use fuel that releases other harmful chemicals beyond just greenhouse gases.
Still, to particularly focus on them rather than just one of many things that need to be reduced and also made more efficient feels a bit misplaced to me. Though I'd imagine that if sail container ships actually prove viable, sail cruise ships might follow.
Some of these megayachts are the size of a cruise ship, but only for one dude and his family. Hence all the pollution just for a handfull of people, who do not even use it most of the year.
