OK, so this sounds a little incredible to me, but it’s in The Guardian so it must be true, right 😛
Shipping by numbers
The world’s biggest container ships have 109,000 horsepower engines which weigh 2,300 tons.
Each ship expects to operate 24hrs a day for about 280 days a year
There are 90,000 ocean-going cargo ships
Shipping is responsible for 18-30% of all the world’s nitrogen oxide (NOx) pollution and 9% of the global sulphur oxide (SOx) pollution.
One large ship can generate about 5,000 tonnes of sulphur oxide (SOx) pollution in a year
70% of all ship emissions are within 400km of land.
85% of all ship pollution is in the northern hemisphere.
Shipping is responsible for 3.5% to 4% of all climate change emissions
Whoah!!! So, if countries start introducing carbon trading, will the ships be covered? Unless the oil producing nations sign up I guess that they’ll still be able to get untaxed fuel and they can always sail under the flag of a country that doesn’t care. Can anything be done about them (presuming stuff gets done about any climate change)?
