That’s hardly low carbon, container ships alone emit almost 20% of the CO2 we are putting into the atmosphere. And Cruise ships emit almost 4x as much as air travel per passenger.
- monk_e_boy 7y agoPer KG of stuff moved it's pretty good.
- DrScientist 7y agoExactly - you need to decouple efficiency of mode, from amount of transport done in that mode if you want to make sensible decisions about which mode is best. Or put it another way - if all that cargo going by sea went by air C02 emissions would be 100x more. Obviously saying sea travel is massively more efficient doesn't obviate the need to reduce that as well.
- Already__Taken 7y agobut once you put people on it you f that number up.
- hwillis 7y agoYou are off by an order of magnitude. Global oceanic shipping of all kinds is <3% of anthropogenic CO2[1]. Closer to 1.5-2% if you include land use changes. You are correct about cruise ships, although it's more like 2-3x.
