Truly shocking!

Health risks of shipping pollution have been 'underestimated'

Britain and other European governments have been accused of underestimating the health risks from shipping pollution following research which shows that one giant container ship can emit almost the same amount of cancer and asthma-causing chemicals as 50m cars.
Confidential data from maritime industry insiders based on engine size and the quality of fuel typically used by ships and cars shows that just 15 of the world's biggest ships may now emit as much pollution as all the world's 760m cars. Low-grade ship bunker fuel (or fuel oil) has up to 2,000 times the sulphur content of diesel fuel used in US and European automobiles.
Pressure is mounting on the UN's International Maritime Organisation and the EU to tighten laws governing ship emissions following the decision by the US government last week to impose a strict 230-mile buffer zone along the entire US coast, a move that is expected to be followed by Canada.
The setting up of a low emission shipping zone follows US academic research which showed that pollution from the world's 90,000 cargo ships leads to 60,000 deaths a year in the US alone and costs up to $330bn per year in health costs from lung and heart diseases. The US Environmental Protection Agency estimates the buffer zone, which could be in place by next year, will save more than 8,000 lives a year with new air quality standards cutting sulphur in fuel by 98%, particulate matter by 85% and nitrogen oxide emissions by 80%.
The new study by the Danish government's environmental agency adds to this picture. It suggests that shipping emissions cost the Danish health service almost 5bn a year, mainly treating cancers and heart problems. A previous study estimated that 1,000 Danish people die prematurely each year because of shipping pollution. No comprehensive research has been carried out on the effects on UK coastal communities, but the number of deaths is expected to be much higher.
Europe, which has some of the busiest shipping lanes in the world, has dramatically cleaned up sulphur and nitrogen emissions from land-based transport in the past 20 years but has resisted imposing tight laws on the shipping industry, even though the technology exists to remove emissions. Cars driving 15,000km a year emit approximately 101 grammes of sulphur oxide gases (or SOx) in that time. The world's largest ships' diesel engines which typically operate for about 280 days a year generate roughly 5,200 tonnes of SOx.
The EU plans only two low-emission marine zones which should come into force in the English channel and Baltic sea after 2015. However, both are less stringent than the proposed US zone, and neither seeks to limit deadly particulate emissions.
Shipping emissions have escalated in the past 15 years as China has emerged as the world's manufacturing capital. A new breed of intercontinental container ship has been developed which is extremely cost-efficient. However, it uses diesel engines as powerful as land-based power stations but with the lowest quality fuel.
"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," said James Corbett, professor of marine policy at the University of Delaware, one of the authors of the report which helped persuade the US government to act.
Today a spokesman for the UK government's Maritime and Coastguard Agency accepted there were major gaps in the legislation. "Issues of particulate matter remain a concern. They need to be addressed and we look forward to working with the international community," said environment policy director Jonathan Simpson.
"Europe needs a low emission zone right around its coasts, similar to the US, if we are to meet health and environmental objectives," said Crister Agrena of the Air Pollution and Climate Secretariat in Gothenburg, one of Europe's leading air quality organisations.
"It is unacceptable that shipping remains one of the most polluting industries in the world. The UK must take a lead in cleaning up emissions," said Simon Birkett, spokesman for the Campaign for Clean Air in London. "Other countries are planning radical action to achieve massive health and other savings but the UK is strangely inactive."
The calculations of ship and car pollution are based on the world's largest 85,790KW ships' diesel engines which operate about 280 days a year generating roughly 5,200 tonnes of SOx a year, compared with diesel and petrol cars which drive 15,000km a year and emit approximately 101gm of SO2/SoX a year.

its a good case for nuclear powered ships.

Unfortunately the public will never allow this. It seems to be a trade off:

1) Nuclear Accident that causes sever radiation posioning/death for smaller group of people near the site.

or

2) Smog, Ozone depletion, that is per person less minor that radiation, but effects the whole world...

I'm a big fan of nuclear, true we do'nt know how to dispose of it completely but at one point we will over come this, or we can not use nuclear and smoke and pollute ourselves into oblivion.

Ships have used nuclear power for some time. Russia used miniature nuclear 'reactors' that provided approx 100kw for remote radio repeater and radar installations in far off places. These things worked great, and some still would be operation if they had not been decommissioned.

There is quite a bit involved here but if fuel prices rise enough then you will see many things that are manufactured offshore come back onshore, closer to the end consumer. That being said, people will approve nuke ships if they cant get thier flat panels cheap from walmart.

The following is a good book on Nuculear, as Bushie would say it, Power.

Terrestrial Energy by William Tucker, I consider a must read to rationally discuss alternate energy sources vs. jihadist oil.

Did Mr. C. just get released from one of Obama's Conservative Reeducation Camps?

Actually, he escaped. We tried everything (short of waterboarding, of course) to bring him around to Comrade Obama's Glorious Socialist Revolution, but Mr. C kept jabbering about Locke's magic "unseen hand" and other wacky laissez-faire stuff. Standard cult deprogramming methods failed. We considered using OxyContin "therapy" on him, but that's proven pretty unsuccessful with other folks of similar political persuasion. Personally, I thought a couple of retired Abu Ghraib guard dogs might do the trick, but I was overruled. Something about the Constitution and protection from "cruel and unusual" punishment...
