Ships pollute port cities more than all cars in the region, analysis shows

At 10 ports about 4,000 ships produced an estimated 1.75 times as much nitrogen oxide as almost one million cars

Ships calling at the UK’s most polluted ports produce more nitrogen oxide pollution (NOx) than all the cars registered in the same cities or regions, analysis has shown.

A report from Transport & Environment (T&E) said that ships were continuing to discharge huge quantities of air pollutants at ports, with Milford Haven, Southampton and Immingham topping the list for emissions of harmful sulphur oxides and fine particulate matter (PM2.5) as well as NOx.
