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
