True scale of C0₂emissions from shipping revealed

From the Guardian:

The true scale of climate change emissions from shipping is almost three times higher than previously believed, according to a leaked UN study seen by the Guardian.

It calculates that annual emissions from the world's merchant fleet have already reached 1.12bn tonnes of CO₂, or nearly 4.5% of all global emissions of the main greenhouse gas.

The report suggests that shipping emissions - which are not taken into account by European targets for cutting global warming - will become one of the largest single sources of manmade CO₂after cars, housing, agriculture and industry. By comparison, the aviation industry, which has been under heavy pressure to clean up, is responsible for about 650m tonnes of CO₂emissions a year, just over half that from shipping.

Sheesh. I am not supposed to fly for holidays anymore, and now even a pleasure cruise is bad. But come to think of it, it would be kind of cool to see giant sailing ships being used for passengers and cargo again.
