As ships get bigger, the pollution is getting worse. The most staggering statistic of all is that just 16 of the world’s largest ships can produce as much lung-clogging sulphur pollution as all the world’s cars.
Because of their colossal engines, each as heavy as a small ship, these super-vessels use as much fuel as small power stations.
But, unlike power stations or cars, they can burn the cheapest, filthiest, high-sulphur fuel: the thick residues left behind in refineries after the lighter liquids have been taken. The stuff nobody on land is allowed to use.
[...]
There are now an estimated 100,000 ships on the seas, and the fleet is growing fast as goods are ferried in vast quantities from Asian industrial powerhouses to consumers in Europe and North America.

Each is a quarter of a mile long and can carry up to 14,000 full-size containers on their regular routes from China to Europe.

Emma – dubbed SS Santa by the media – brought Christmas presents to Europe in October and is now en route from Algeciras in Spain to Yantian in southern China, carrying containers full of our waste paper, plastic and electronics for recycling.

Bunker fuel is also thick with sulphur. International Maritime Organisation (IMO, the UN body that polices the world’s shipping) rules allow ships to burn fuel containing up to 4.5 per cent sulphur. That is 4,500 times more than is allowed in car fuel in the European Union. The sulphur comes out of ship funnels as tiny particles, and it is these that get deep into lungs.
Thanks to the IMO’s rules, the largest ships can each emit as much as 5,000 tons of sulphur in a year – the same as 50million typical cars, each emitting an average of 100 grams of sulphur a year.
With an estimated 800million cars driving around the planet, that means 16 super-ships can emit as much sulphur as the world fleet of cars.
