I didn't want to fly – so I took a cargo ship from Germany to Canada
- flounder3 7y agoThere is no mention of the type of fuel the cargo ship burned while outside of port (bunker fuel, anyone?). The three citations at the end of the article simply reference generic sites, not specific information.
- Symbiote 7y agoPossibly something awful, but irrelevant for the passenger on the scale of moving a 100,000 tonne ship, so we should consider that issue separately.
- DoingIsLearning 7y agoCouldn't we make the same argument for an airliner: X cubic meters of CO2 divided by 200 odd passagers in an airliner. Vs. Y cubic meters of NOx/SO2/CO2 divided by that person and however purchased the freight goods in the container. We could argue that the cargo ship would sail irrespective of that passenger, but we could equally make the same reasoning for people buying last minute seats that would otherwise fly empty. Without doing the maths this risks making very fortunate people feel good about themselves and distracts from corporation practices that are orders of magnitude more harmful. Again I do not have the numbers but what is the carbon impact of halting all german flights versus decomissioning all german coal plants?
- dwild 7y ago> We could argue that the cargo ship would sail irrespective of that passenger, but we could equally make the same reasoning for people buying last minute seats that would otherwise fly empty. Sure but the cargo ship business isn't moving passenger. If they always fill all the passengers rooms, they won't decide to bring more ships into the equation. Whether there's 0 passenger or 15, the ship will still go through that same amount of fuel. Someone else did gave some good example of energy usage that a passenger will cause, like the water he will consume will need to be desalinated, or if he get sick and that require diverting a ship.
- jocoda 7y ago> ships rarely have room for more than a dozen passengers Reason is that you need a ship's doctor if there are more than 12 passengers.
- gambiting 7y agoI mean....yes. Yes, your carbon footprint is smaller by travelling slower. But you need to be in an extremely priviledged position to be able to afford travelling this way, both financially and time-wise. Cross-atlantic is obviously quite extreme, but even within Europe a train is not really a viable alternative for a lot of people, when I go to visit my family the choice is either a ~£100 Ryanair ticket for a 2 hour flight, or around 40 hour long train journey that will cost at least £500 one way. I just don't have the money or the time to travel this way. I don't know what's the right answer here - I suspect it is "just don't travel then".
- scandinavegan 7y agoI agree with your main point! I want to state that upfront so that you don't think I'm arguing about the current situation, apart from addressing specifics. You will have to add some time to flying scenario. You have to arrive early to the airport to go through security (2 hours?), you have to wait for your luggage after landing (30 minutes?), and since airports are usually located outside of the city center you have to add travel time to and from the airport (45 minutes in each direction?). In my example that's an extra 4 hours added to the 2 hours time flying. It's still a lot less than going by train, but with train you get the convenience of being able to run onto the platform 2 minutes before departure, you end up in the city center, you pick up your luggage and leave, and you usually have more space which makes it easier to work on the train if needed. Also, flying is extremely subsidized and tax-exempt. I just read articles (in Swedish, so I don't know if anyone wants links) claiming that air tickets should be between 50% and 95% more expensive if they had to carry their own costs, if there was a tax on airplane fuel, and so on. So the price for air tickets probably doesn't reflect their real costs, and obviously doesn't take the environmental effect into account. But even adding the extra time and extra cost, it would still be faster and cheaper to fly than to take the train, which is unfortunate from an environmental perspective. I wish we had faster trains, and a lot more overnight trains so that you could start your travel in the evening and wake up in a new city. It wouldn't help with a 40 hour trip, because it would still be two nights with one full day on the train. This might work for people who can work remotely on the train, but not for everyone. Start you journey on Thursday night, work Friday on the train, and arrive Saturday morning at the destination. Someone I know did this recently while traveling to a conference, and the company obviously paid for the tickets. This doesn't help when visiting family, but for work travel, train could be an option. I have an airplane interested colleague and I asked him about environmental fuels. He said that aviation biofuel already exists, and it's just a question of adoption and scale. A carbon dioxide tax might push air companies towards biofuel, or you could have the option of green biofuel departures and let the customers decide if they think it's worth the extra cost. I'm sure my train-traveling conference goer would consider that option if it was available. As I said, I agree with your main point that if you just look at price and travel time today, the less environmentally friendly option makes more sense. It would make more sense if the slower option was also much, much cheaper than flying, because that would encourage more people to use that option.
- ZeroGravitas 7y agoSeems like offsetting would be easier? That's one of those economically sensible things that normal people dont seem to like though.

- dsalzman 7y agoCargo ships are unregulated and burn the lowest grade oil called bunker fuel. These ships can emit the equivalent sulfur emissions of 19 million ICE vehicles.[1] [1]https://www.cadmatic.com/resource/articles/does-one-ship-pollute-as-much-as-50-million-cars- https://www.cadmatic.com/resource/articles/does-one-ship-pol...
- acrooks 7y agoNot as of January 01 - there's a new regulation this year that imposes a sulfur cap on fuel burned by cargo ships [1]. Most ships must now burn more expensive and cleaner fuels. Some ships - mostly larger ones - still burn HSFO but they can only do so because they've installed "scrubbers" which clean the emissions to reduce the amount of sulfur emitted into the atmosphere. It's an open question whether scrubbers are really helping or just a diversion from purchasing higher quality fuel, but it's only economical to install scrubbers on the very big ships and so the large majority of the ~50,000 strong merchant marine fleet don't have them installed.

- asdfadsfgfdda 7y agoThe carbon calculations seems questionable. The author should include all energy used on board the ship, which is entirely from fossil fuels. The energy required to desalinate seawater for drinking/washing was probably greater than a flight. Also, an additional, unnecessary person on the ship is slightly increasing the risk of diverting the ship because of a medical emergency. Imagine how much carbon would be burned if this massive ship had to turn around to drop off a sick passenger.
