P&O Cruises and Cunard have stated an intention to remove single use plastics from the hotel operation on their ships by the end of 2022.
The move follows a raising of awareness of the problem thanks to programmes such as BBC’s Blue Planet.
Carnival UK president Josh Weinstein said "Whilst we have stringent regulations and procedures on board our ships for recycling, we need to go to the source of the supply chain to encourage changes to packaging and remove single use plastic products from our hotel operation.
"We are in discussions with our suppliers to try to influence the removal of single use plastic in products such as straws, water bottles and food packaging wherever possible, as well as reviewing our wider sourcing strategy of the most environmentally friendly products across the board.
"Programmes such as Blue Planet have shone a light on the impact plastic can have on our seas and it is our responsibility, as an ocean-going cruise line, to take action now, however many hurdles we have to face along the way."
