Shipping a major polluter

16 of the world’s largest ships can produce as much lung-clogging sulphur pollution as all the world’s cars.

Unregulated emissions

"In international waters ship emissions remains one of the least regulated parts of our global transportation system. The fuel used in ships is waste oil, basically what is left over after the crude oil refining process. It is the same as asphalt and is so thick that when cold it can be walked upon . It's the cheapest and most polluting fuel available and the world's 90,000 ships chew through an astonishing 7.29 million barrels of it each day, or more than 84% of all exported oil production from Saudi Arabia, the worlds largest oil exporter." 


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.

Thanks to decisions taken in London by the body that polices world shipping, this pollution could kill as many as a million more people in the coming decade – even though a simple change in the rules could stop it.

There are now an estimated 100,000 ships on the seas, and the fleet is growing fast as goods are ferried in vast quantities
