    Well no because it wouldn't be true. Depending on her port of departure, she will contribute between 0.8 and 2 tonnes of emissions.

    Yep let's close down the internet and all intranets. That'll be you out of a job then. Now just who are you going to get to sell this wheeze to the Americans, Chinese, .....?

    If I hitch a ride in Apos 40 ton lorry then my body mass will add an extremelly tiny amount of Carbon as a percentage If I get a bunk in a loaded cargo ship ditto we are not aguing for everyone to stay home just think about what we are doing and make good desisions based on the evidence

    I cant say what one humans presence on said cargo ship equalls and neither can you your examples relate to Cruise ships another thing entirelly I would agree though that what is shipped and why becomes an inportant part of our collective desision making and plastic crap should no longer be part of such cargo

    To answer your points arithmetically

    1 Cargo ship (in your example) = 50,000,000 cars per year? (you dont say)@ 4 Tonnes per car (per year)= 200.000.000 tonnes per year?

    I've only got 5 years left anyway, my sunk carbon cost to the planet is a fact of history as is yours and everyone else's, I'm 60 if I'm lucky I might have 15 years left so something like 80% of my cost to the planet is already spent, I can't undo that.

    The time for doing something about climate change was 30 or even 40 years ago, that's when we really had to start, we should have been off oil by now.

    And you make my point, the action required to mitigate the brick wall event we are rapidly hurtling towards is so large that no population will buy into it.

    What will happen is that more and more people will wake up and start to panic, XR is one manifestation of this but it's already too late, however I support them some action is better than no action.

    We use a cube of crude oil about 1 mile on each side every year 1 CMO (an official energy unit now I believe), that's just the oil, the total energy used by humanity each year is the equivalent of about 3.5 CMO.

    These are figures for 2006 from the link to the CMO definition above.
    upload_2019-8-17_15-40-45.png

    Todays numbers are not much better for the renewables and the total energy use is higher.

    My point is that you cannot have any of the things we take for granted in the modern world without that energy and you can't have a population of 7.7 billion human beings without that energy.

    So when you try to take away that energy from any population that is accustomed to the life provided by that energy they will not accept that change, they might all see the disaster staring them in the face but they will just look around in panic and end up doing nothing.

    Most people in todays modern industrialised western world do nothing of any real value including programmers like me, so what I make a few factories slightly more efficient through scheduling their machines processes, it's not as if we really need those factories in the first place it's just that they are part of the technological organism that we all live in and it's that organism that's killing the planet.

    If another Carrington event or something a few times larger happened tomorrow and the power grids really did actually fail through transformer meltdowns, you would see within a few weeks just what a world on a restricted energy budget looks like, or rather some of you would see it as most of you would just die.

    But climate change will achieve the same thing just slightly slower.

    Just look at that table and you see the scale of the problem.

    That's why I say it is already too late.

    I take his point but the sacrifice, that in reality is going to have to be asked for, is larger than any population will accept.

    Wrong you are talking about Sulphur emissions not CO2, specifically container ship Sulphur emissions.

    You may be right but it wont change the nature of the sacrifice or my responce to it , I cant now go back and not know the reality, or my moral responability to present that awfull choice, in the end how we define ourselves in relation to the fiction of the other is for each of us to decide.

    On the cruise ship hypothesis that is plausible, burning 1 litre of diesel produces about 2.65 kg of CO2

    Cruise ship burns about 4,200 litres an hour that's 100,000 litres a day and about 600 tons of fuel in 7 days.

    So 7 days is about 700,000 litres or 1855 tons of CO2 so a large cruise ship with 2000 passengers yeah 1 ton a piece.

    I am talking about total emissions whose main constituent is carbon. Sulphur is present in all fuel oils to a greater or lesser extent and is/was most prevalent in HFO - heavy fuel oil - which took-over from coal to power steamships. The industry has cleaned-up Marine Diesel quite considerably and removed many contaminents. But all carboniferous fuels contain Sulphur and it is injurious to the environment

    Marine Diesel is a lower fraction (just above HFO and road tar) than Road Diesel and with a high carbon content. It also contains other toxic contaminents which add to its unfriendliness. Transport costs would probably quadruple if ships had to burn clean fuels.

    Our agreed estimates are fine if we're only talking about a ship's main engine. But you'd need to increment that by around 10% for a freighter and around 20-25% for a passenger vessel due to all the generators and pumps that are also oil-burning. And if some mad Mullah decides to go for a bit of piracy, tben yon ship is still burning fuel rather unproductively.

    2010 estimate 1 billion cars in the world.

    1 Litre of diesel is 2.65 kg of CO2
    1 Litre of petrol is about 1.7 kg of CO2

    Lets pretend they all burn 6 litres a day on average and they are all petrol.

    1,000,000,000 cars times 6 litres = 6 billion litres of petrol per day.

    That's about 10 billion kg or 10 million metric tonnes a day from cars (just cars not lorries and buses).

    A container ship burns about 225 tons of bunker fuel a day so 15 of them burn about 3375 tons of fuel a day.

    So 15 container ships generate about 8940 metric tonnes of CO2 per day versus 10 million metric tonnes a day for cars.

    Metric and imperial tons are not the same but they are close.

    So do you think 8940 tonnes is a bigger number than 10 million tonnes?

    People have no concept of scale, you just throw out numbers like 15 container ship generate more CO2 than all the worlds cars and it never crosses your mind that you are at the wrong scale, it's a joke.

    edit: that's 225 tons for an 8000 TEU container ship.

    Jim, I believe my figures to be accurate but I'm having problems posting links on this phone. Google "emissions container ship compared to cars" and look for pages from quora.com and medium.com which make the point.

    Your figures are obviously wrong, you took the 15 ship number from the Sulphur pollution report and then conflated it with CO2 emissions, you're wrong, it's basic arithmetic.

    5000 container ships in the world roughly.

    Total emissions from them probably about 44 million tons a day if they were all 8000 TEU probably more like 30 million tons a day given many will be smaller, yes more than cars, total emissions from 15 ships more than all cars NO.

    Possibly but that doesn't negate the fact that shipping is responsible for massive releases of emissions. And, I would argue, Sulphur is a worse pollutant as it can not be fixed, as carbon is, by vegetation.

    Not possibly, absolutely!!!

    Sulphur it gets washed out of the atmosphere as sulphurous acid, acid rain, like all pollution it's bad but not a fraction as bad as a gas that accumulates and that reflects infrared radiation back to the ground, just to be clear heat.

    And this is what you do and why you get the reactions you continually get from people on this forum, I mean really.

    More like what your actualy doing is trying to justify you attack on Greta using a comercial cargo ship to return to Europe on by trying to compare its carbon footprint to a cruise ship:troll:
