Bullsh*t. Oil tankers and the clue is in the name carry oil around the world from where it's found to where it's used. How far would your motorbike go without petrol? Where do you think it comes from? In terms of shite we churn out in terms of tonnes carried per mile it's very low. Also under international law by the end of this year all ship's will have to be fitted with exhaust gas scrubbers or burn fuel with less than 0.1 percent sulphur. These scrubbers cost over a million dollars a pop so require significant investment from owners. People talk shit because they believe what tv said, I am on ships since 1990 and in cruise industry’s since 2004 ships yes pollute but not as much as they present, we clean our exhaust gas and we burn low sulphur fuel, we have electrical connection to connect to shore side while in port so we don’t use our engines, ports are not prepared for it, just few has that possibility. So it is not up to the ships only but ports as well. It is just campaign that recently started in US against big cruise companies, and reasons are completely different. Pollution is just excuse.
