Emissions from cruiseships in Europe are far outstripping those from every car on the road, it has been claimed.
Green group Transport & Environment (T&E) said its analysis shows that in 2017 Carnival vessels pumped out nearly 10 times more sulphur oxide (SOX) around European coasts than 260m vehicles.
The figure for Royal Caribbean Cruises (RCCL) is four times that of the car fleet.
