Shipping emissions three times higher than thought

Greenhouse gas emissions from shipping are nearly three times higher than previously believed, according to a leaked UN study.

It calculates that emissions of greenhouse gases from ships have reached 1.12 billion tons of carbon dioxide a year and amounts to 4.5 per cent of all global emissions.

By comparison the aviation industry, which has been under heavy pressure to clean up, is responsible for about 650 million tons of carbon dioxide a year, just over half that from shipping.
