The consultants’ report provides figures for cruise ship they deem typical. Elsewhere in the Report the cruise ship Crystal Symphony is mentioned as the largest that can get into the new dock. This vessel would emit 2.5 to 3 times more NOx than shown in the images.
An argument used by supporters of the terminal was that vessels would be using ‘low sulphur’ diesel which is ‘very similar to automotive diesel’. This is misleading. Since 2009 in the EU the maximum sulphur content for automotive diesel has been 10 ppm, which is 10,000 times less than ‘low sulphur’ marine diesel (we are looking at creating an image to show this too)…The problem of excessive air pollution from stationary cruise ships in cities is however easily solved by installing shore-to-ship power systems, so the national grid can be used and onboard diesel power is not required.
