    The biggest container ships produce more emissions than every car on the planet. Granted, I think there’s at most a half dozen of those in operation, but that’s still 6x more than every car on Earth.

    I remember hearing that during COVID lockdowns the first year, an estimated 50% of cars were off the road and total annual emissions dropped 2%.

      Is there a souce for that?
      It doesnt seem consistent with this one
      https://ourworldindata.org/co2-emissions-from-transport

      but this is limited to CO2 emissins, so i’m wondering what type of emissions are being counted is there any data on that.

      I had a quick look at the “all GHG” data in EDGAR and that also seems to shows road transport quite a lot larger than shipping.
      But I’d need to spend a bit longer looking at the data to figure out if i’m using it correctly.

      Could it be based on Particulate matter emissions??
      PM emissions don’t do much if anything to directly intensify climate change - not like GHGs

        Yeah it really doesn’t seem to track with my knowledge in regards to shipping efficiency. AFAIK those big ass container ships are on par if not more efficient than a train.

      I just found that the 16 largest Ships emit as much as all cars. Did not check the source further.

      But that really depends on how you measure and define pollution. As others have pointed out container ships are still pretty efficient. But of course they should get better too. Like everything!

      Source: https://cedelft.eu/publications/the-basic-facts-how-do-the-emissions-of-ships-and-cars-really-compare/

      As I have said, I did not fact check it further because it is quite late here. Just wanted to give information to that claim and please correct your statement (:

        Appreciate it, because you and I probably read the same stats but I was pulling it from memory from whenever I heard it (like 7-10 years ago).
