oil contains high concentrations of toxic fuel compounds banned from use in most<br />

o<strong>the</strong>r industrial <strong>and</strong> consumer applications.<br />

The pollutants emitted from burning this dirty fuel leads to acid rain, global climate<br />

changes, particularly over oceans, <strong>and</strong> damaging health effects for communities living<br />

near major port areas.<br />

Analysis by Carnegie Mellon <strong>and</strong> Duke Universities suggests that smokestack<br />

emissions 52 from ships may account for half <strong>the</strong> sulphur found over <strong>the</strong> world's<br />

oceans, <strong>and</strong> 60 percent of <strong>the</strong> airborne sulphur in <strong>the</strong> North Pacific <strong>and</strong> North Atlantic.<br />

Worldwide, ship sulphur emissions rival <strong>the</strong> sulphur emissions of <strong>the</strong> world's largest<br />

economies, resulting in staggering proportions when compared to sulphur generated<br />

on l<strong>and</strong>. Total worldwide ship sulphur emissions equals 43 percent of <strong>the</strong> sulphur<br />

produced by <strong>the</strong> US <strong>and</strong> 53 percent of that produced by OECD Europe. Researchers<br />

conclude that ship emissions are a critical <strong>and</strong> overlooked element in <strong>the</strong> global<br />

climate change debate <strong>and</strong> in emissions modelling.<br />

Adding to <strong>the</strong>se concerns, to <strong>the</strong> results from <strong>the</strong> Indian Ocean Experiment in 1998-<br />

1999 suggest that aerosol emissions from ships, power plants <strong>and</strong> industrial sources<br />

may be trapping solar heat by "burning away" clouds through emissions of sulphates,<br />

nitrates, soot <strong>and</strong> ash. Such an effect would increase global warming through loss of<br />

heat-reflecting cloud cover."<br />

Research published in 2007 claimed 60,000 people died each year as <strong>the</strong> result of<br />

ships' high levels of sulphate emissions.<br />

Information put out by <strong>the</strong> service, whose centrepiece is <strong>the</strong> website 53 , stresses <strong>the</strong><br />

benefits brought by container shipping, particularly <strong>the</strong> sharp reduction in global<br />

transport costs achieved by <strong>the</strong> industry.<br />

The service marks an unusual foray into <strong>the</strong> public arena by a group of senior<br />

executives at <strong>the</strong> world's 24 largest container carriers. Many of its members,<br />

particularly <strong>the</strong> many family controlled lines, are normally publicity-shy.<br />

The shipping lines reject criticism of <strong>the</strong>ir environmental record, saying large, modern<br />

container ships create far fewer emissions moving a tonne of cargo for a given<br />

distance than any o<strong>the</strong>r means of transport. Most lines have also reduced <strong>the</strong> speed of<br />

<strong>the</strong>ir ships in recent months, <strong>the</strong>y point out. The move, intended to lower consumption<br />

of expensive fuel, has reduced carbon emissions.<br />

Emissions from some shipping lines ships were down 35 per cent following a<br />

reduction in <strong>the</strong>ir average speed from 24 to 20 knots, even after taking into account<br />

<strong>the</strong> emissions produced by <strong>the</strong> extra ship needed to maintain weekly services with <strong>the</strong><br />

slower speeds.<br />

However, like o<strong>the</strong>r debates about <strong>the</strong> impact of transport on <strong>the</strong> environment <strong>the</strong>re<br />

are different claims. Some claim container shipping is <strong>the</strong> most environmentally<br />
