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 />
