Says James Corbett, professor of marine policy at the University of Delaware: "Ship pollution affects the health of communities in coastal and inland regions around the world, yet pollution from ships remains one of the least regulated parts of our global transportation system." It sounds serious, but how bad could it be? Staggeringly, if a report by the UK's Guardian newspaper is to be believed. According to their story, just one of the world's largest container ships can emit about as much pollution as 50 million cars. Further, the 15 largest ships in the world emit as much nitrogen oxide and sulphur oxide as the world's 760 million cars.

The problem isn't necessarily with the ships' 109,000-horsepower engines that endlessly spin away 24 hours a day, 280 days a year. In fact, these powerplants are some of the most fuel efficient units in the world. The real issue lies with the heavy fuel oil the ships run on and the almost complete lack of regulations applied to the giant exhaust stacks of these container ships.

The good news is that pressure is building from various governments around the world, including the United States, which just recently introduced legislation to keep these ships at least 230 miles away from U.S. coastlines. Similar measures are likely to follow in other countries like the United Kingdom.

maybe its becasue those 5 ships transfer 760 million cars :chuckle

that's pretty crazy, i wonder how much green technology has actaully been implemented into the shipping industry

well meat factories (factory farms) produce more green house gases (methane, nitrous oxide) then all of the worlds trucks, cars, planes and ships combined!!!! those damn cows fart a lot...

"Globally, the livestock sector generates 18% of all anthropogenic greenhouse gas emissions measured in carbon dioxide equivalent.57 This is due primarily to its emissions of the potent and persistent greenhouse gasses, methane and nitrous oxide, as well as its production of smaller quantities of carbon dioxide. Remarkably, the livestock sector produces 37% of the world’s anthropogenic methane emissions and 65% of all anthropogenic nitrous oxide emissions.58"

DAMN...but those ships do transport a lot of stuff for us. They'll probably need to add like 5 millions cats to reduce the emissions...

that's a lot of pollution..but ask yourself: if one car could carry 500 kilogrammes of cargo, how many cars would it take to carry 150,000 tonnes worth?

the article ( http://www.guardian.co.uk/environment/2009/apr/09/shipping-pollution )says that cars emit 101 grams of sulfur oxides in a year, while the diesel engines in a container ship emit some 5,200 tonnes. So 300,000 cars x 0.101 kilogrammes SOx each = 30,300 kilogrammes SOx..

when you look at the numbers that way, it starts to show that container ships are actually a lot more efficient than the article says, and that's being generous with car carrying capacities. they're still not great, but a lot better than what's implied.

then consider that a car can't float across the ocean without the aid of a ship :)

I agree that these giant ships are efficient, as stated in the article, but I think the article's point is that the emissions generated by the shipping industry, despite its efficiency, still pumps too much crap into the atmosphere, unregulated.

I'm sure my car runs more "efficiently" if I ran it cat-less too...so how come these ships puffs out unfiltered heavy-oil emissions?
