"15 of the world's biggest ships now emit as much pollution as the world's 760m cars"
Health risks of shipping pollution have been 'underestimated' | Environment | guardian.co.uk
Quote:
This worries me, not simply because of the effect, but because of the lack of alternatives. Bunker fuel, for those who don't know, is what's left over when you distill out all the stuff like gas, diesel, and natural gas. It's barely liquid, and needs to be heated to get it moving through the fuel lines. While we're worrying about miles per gallon on land, these ships are getting a few hundred feet per gallon. In the short term, it seems the way to minimize health risks in the short term is to require burning of clean fuel near land. Here's a post from another forum dealing with cruise ships in Alaska: Quote:
Even when we have clean shipping zones around the coast, out on open water it's still a problem. The quick and easy thing to do about greenhouse gases is to retrofit ships with underwater exhaust pipes that diffuse everything into the water; this, of course, just shifts the problem to water pollution. Suggesting that private industry start operating nuclear-powered ships would rightfully open up a can of worms, but it seems to me like the only thing that could generate enough power to move these ships. I really don't know what can be done about it. |

A few hundred feet per gallon? I don't know where you get your facts, but here's something to think about: On a single litre (about a 1/4 U.S. gallon) of fuel, one tonne of freight can travel 240 km by ship, compared with less than 100 km by train and less than 30 km by truck Every mode of transportation carries an environmental footprint, and it’s important to note that the elimination of one maximum size Seaway vessel would require the addition of 875 truckloads on our highways, or the addition of 225 railcars to the rail system. Any addition of trucks or rail cars to our roads and railways would only serve to exacerbate current issues of congestion faced by those modes of transport and associated environmental effects. Think about that the next time you are idling in traffic with a bunch of transport trucks on the highway. HWYH20.COM Quote:

yes, it would be crazy! North American economy would be in even worse shape than it is now! That's partly why having the Great Lakes system makes such sense. It opens up places like Chicago, Milwaukee, Gary, Indiana and Burn's Harbor, Rochester, Cleveland, Toledo, Saginaw to International shipping via the St. Lawrence Seaway. Most of the road salt used in those cities and surrounding communities comes from Goderich, Ontario (a small town of about 15,000, and one enormous mine), and it comes in on Canadian ships throughout the shipping season.

True. But how much longer can this planet bear an economy – and the lifestyle that is dependent upon that economy – like that of the U.S., especially since now that other countries, like China and India, are coming up to speed?

I don't honestly know and it's slightly off topic, but I always feel a little embarrassed that now that we've enjoyed the lifestyle, we can point our fingers at the 3rd world who are just getting there and say, "oh, you can't do that, it's bad for the environment." On the other hand, some of the 3rd world countries who can't compete in heavy industry are starting to kick the crap out of the 1st world in high technology areas. Also, notice Japan wiping the floor with the Big Three automakers.

this will be met with derision, as people generally have their minds made up about those things, but the US auto industry is making vehicles just as reliable as the rest of the world now. Twenty years ago, the argument could be made that American cars were inferior to those from Asia and Europe in terms of quality; that simply isn't the case anymore, and reliability studies will support that claim.
Of course, that's not going to change anyone's mind who insists that American cars are inferior, even in the face of data that shows otherwise. But it's those misconceptions as much as anything which has crippled the US auto industry.

If a shipping company decides they're becoming green, the rise in costs will probably make them lose customers. The only time politicians react is when a oilspill, or something else that has a huge visual impact happens close to home. Then people get outraged, and politicians who want votes try and get laws passed. I might be a bit cynical, but I believe that's how it happens.

Nucular, it's pronounced Nucular.
Thats about the only way we'll get around this. It's all very well say 'omg, teh ships are teh evilz!', but how else do you propose we get all these goods around the world? Air? That'll be even worse.

so let's think about this. say both msd and lucifer are right. where does that leave us? well, the short of it is that the present model of capitalism is simply not sustainable. ocean shipping is fundamental to the entire globalizing capitalist order...which is a result of a significant mutation in the old centralized production model into one that's liked via automated forms of just-in-time systems, and so is comprised of supply chains..one of the main drivers behind this is that it enables externalization of costs like social and environmental responsibility, and enables the race to the bottom in terms of wages and working conditions---which is of a piece with the autonomization of capital....it's a highly centralized mode of doing things, but one which exploits newer technologies to get around problems of older-style mass production--for example j-i-t systems typically have quite flexible assembly lines, which enable shorter production runs...so it's a mode that in many ways is as or more centralized than was the older factory system, but it appears not to be. costs can be driven down by avoiding social and environmental responsibility and by continually pushing down wages through manoevering bids within the supply pool such that it makes sense from a profit viewpoint--but no other--to spread elements of a production chain all over the place geographically and connect the elements with container ships and combinations of rail and trucking. but there's a downside to this spreading, and it's in the transport linkages that hold the system together that you can really see them, at least from an environmental damage viewpoint.
but these things are invisible for most folk, so there's little in the way of politics surrounding this. this form of centralization is THE problem that explains this entire mess that's being discussed in this thread. to get around it, there'd have to be a different politics of production and distribution--an emphasis on decentralization, say---pressure to move the elements of production closer to the rest of the system (distribution, etc) and to each other--a movement for force capital to accept the social and environmental responsibilities that follow from their ability to extract profit at all---folk would have to start seeing capitalism as a social system, it's outcomes as following from choices, not from forces of nature, not from some magical hydraulics that is somehow assumed to explain how markets operate. this is the world that neoliberalism brought us all--to change it, we'd have to rid ourselves of the whole of the fog that it cast around capitalism and force a very different arrangement. short of that, lucifer's right--and so is msd--and if that's the case, we could all be fucked.

I think, if anything, the OP is simply attempting to inform us of what many do not know. I am with Lucifer on this one. It is a an economy of scale. Yes, the ships are making a lot of pollution but given the amounts of goods they carry vs. the amounts that trucks and trains can carry, they are actually polluting less. Comparing ships to cars is disingenuous. It's not as though people are taking ships to the corner store for a pack of smokes. What needs to be done is that governments and industry need to invest now in clean power generation. Perhaps it is nuclear. Perhaps it is hydrogen. Perhaps it is using nuclear to create hydrogen. Maybe its something that will be invented by a kid in kindergarten today. The point is, we need to invest in this today.

i still think we're looking at this in too narrow a way: the Problem lay with the architectures of the socio-economic system that these transportation elements are part of.
for example if you are managing a supply chain by computer, the components are updated in real time, the system looks coherent and tight in terms of flows of objects and, by extension, geography. but that geography is possible because you have regular connecting transportation linkages--without them, it makes no sense to have, say, a facility in southern china, a facility in sri lanka, a facility in the bahamas and a facility in new jersey be part of the same production cycle. the problem then is ot economy of scale but a particular set of ways to organize production around economies of scale. it's a very basic political question.

As with most major problems, there are many facets to their solutions:
At this point in our technological development, I expect nothing less than attempting to make efficient use of energy wherever possible. This is just one example. roachboy is on the right track in terms of this being more than just a fuel usage issue. The production and distribution channels (not to mention packaging and storage) have been globalized and are another serious aspect to the problem. That I can pick up a cheap bunch of bananas here in Toronto at any given time is something I take for granted.

Even worse than that, do we really want the Somalian pirates getting hold of a ship with a nuclear reactor on it? The Navy can get away with it because no one's gonna be able to take over a naval ship. The civilian ships would have to also be armed to the teeth before they were safe enough to become nuc boats.

A more immediate solution than converting ships to other power sources (e.g. nuclear, fuel cell, etc) is burning cleaner fuel (e.g. diesel vs bunker). But even on existing ship engines that have high pollution emissions, you can add scrubbers that are very effective at cleaning the stack exhaust...this is just like has already been done with many landbased dirty-stack industries. And note that there are scrubber designs that don't just wash the dirt into the ocean, the dirt can be removed from the exhaust, stored (does not take up significant onboard space) and later disposed of properly in a non-polluting manner.

I agree that the global system of production and distribution is the main part of the problem but I don't see that system going anywhere anytime soon and as long as it exists, there will be a demand for shipping massive amounts of goods around the globe. Far better to find cleaner methods of shipping those goods.
Another vote here for Zeppelin shipping. There have been some massive advancements in Germany in the past 10 years.

the global production system could be changed quite rapidly, actually. clamp down on capital flows and make it more expensive to move goods over long distances. for example. the system took shape very quickly and presupposed particular conditions--those conditions can change. we aren't talking about a revolution.
this despite my fondness for everything zeppelin.

Even energy delivery systems need to be changed. If you look at the loss inherent in the current systems, you'd be appalled. Both problems are one of attempting to do everything over long distances, which is wasteful.
We're hanging on to our traditional models despite the fact that they were designed for intercity distribution, rather than international.

This doesn't really apply to this argument, but I work in logistics, and FYI our business is quite slow these days. Luckily I'm on the shipping end of things, so I get all these great rates from trucking companies dying for business. Example: A few weeks ago I scored a FTL (full truckload) from near LA to Baltimore, for $760. The opposite lane (Baltimore-LA) is typically $3-4k.
Also FYI, weight is just one factor in shipping things. Cubic feet (Sometimes I do shipments of pillows - FTL but only 5-6k lbs. FTLs can go up to 50k lbs.), commodity (some carriers won't do fragiles, or stuff that's too expensive.), expedited shipments, trade regulations, etc.
