Levels of pollution on some cruise ships’ decks are worse than in the world’s most polluted cities – an investigation by Channel 4 Dispatches has found.
The undercover investigation on Britain’s biggest crew operator P&O Cruises aimed to find out how clean the air holidaymakers breathe when on a ship is.
It focused on the levels of ‘ultra-fine particles’ found in the air and around the cruise ship and emitted from the fuel the ships’ engines burn.
But while passengers hope to escape the dirty air of cities for some fresh sea air – the investigation found cruise ships are having a negative impact on the environment.
One cruise ship can emit as much particulate matter as a million cars in a day.
