The report also mentions these points:
- " CO₂emissions are set to rise by a further 30% by 2020."
- " Other pollutants from shipping are rising even faster than CO₂emissions. Sulphur and soot emissions, which give rise to lung cancers, acid rain and respiratory problems are expected to rise more than 30% over the next 12 years."
- " A recent peer-reviewed study of shipping emissions found world shipping led directly to 60,000 deaths a year."
The best metric is still around volume or weight measurement. How much cargo is shipped that generates 1.12 billion tons of carbon for ships? How much cargo is shipped that generates the 325 million tons of airborn-shipping carbon?
