Why we see the only sustainable transport is fair transport:
- 15 of the world’s biggest ships may now emit as much pollution as all the world’s 760m cars.
- Low-grade ship bunker fuel (or fuel oil) has up to 2,000 times the sulphur content of diesel fuel used in US and European automobiles.
- The calculations of ship and car pollution are based on the world’s largest 85,790KW ships’ diesel engines which operate about 280 days a year generating roughly 5,200 tonnes of SOx a year, compared with diesel and petrol cars which drive 15,000km a year and emit approximately 101gm of SO2/SoX a year.
- 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
