[Debunked] A liner or freighter pollutes as much as 1 million cars...and 1000 tractors? Really ?

I'm sick of seeing the news spread that 1's only big cargo ship or cruise ship would pollute as much as 1 million cars! And who is the stuff of some misinformation sites ... see even major media that relay information in a more or less clear!
I even read recently that the 20 biggest boats pollute as much as ALL the cars of the Earth !!!
Mouahahahhah, as there are more than 1 billion cars on Earth, that would mean that a boat pollutes more than 50 millions of cars, there I am joking and I laugh yellow!
This information, these infox or intox, are nevertheless widely relayed on social networks and for good reason: it makes the use of the car easier! It is well known that in terms of pollution: it is always the fault of the other! We are in it!
This subject is there to take stock and help those who believe in it to see more clearly!
a) 1er lie: there is pollution and pollution!
The people who relay and disseminate this intox assume that it concerns "all pollution" ... serious mistake!
This statement does not concern that fine particles, and why? Because modern cars do everything to minimize this kind of pollution.
Remove the particulate filter (DPF) and the catalyst and the 1 million will melt like snow in the sun !!
Note that:
a.1) the FAP, is only a particle TRAP and it must be regenerated regularly and that in this case, it is possible that a large part of the particles emerge suddenly because the regeneration (= burning in the FAP) did not work properly!
a.2) The catalyst is inactive cold (so 30% of the routes of the French ... moue moue ...)
b) 2ieme lie: the CO2. Boats are the most economical transportation in the world on energy efficiency and therefore energy consumption so the CO2
On the CO2, the big boats are the most efficient to the useful ton transported!
In other words, it is those who pollute the point in "CO2 emission / useful ton.Km"
c) And these particles compared to agricultural tractors? Huh? Come on we laugh!
Agricultural tractors are much less polluted than cars, especially the old park ... in short it smokes black!
I would not be surprised if we could therefore reduce the ratio to 1 boat to 1000 on tractors (in order of magnitude) ... Ah right away that makes less "guilt-free" ... and if we compare to lawn mowers lawn, I presume, that the figure is less than 20 ... How many lawn mowers are there in France?
Finally, some boats inject water and have efficient anti-pollution processes (more modern than on cars!), Like the MAN HAM: consume less-car / ham-and-water-injection-man anti-nox-in-the-motor-marine-t14241.html
Here I stop there for now, if you have other arguments, let's talk about it! The numbers in point c) can be easily refined ... if necessary ...

The last point is confirmed, sulfur oxides largely contribute to lowering the greenhouse effect, thank you Izy: co2-climate-change / the-latest-figures-and-meteorological-consequences-of-global warming-t13878-1480.html # p460649
