Ponant takes caring for the sensitive environments in which its ships operate very seriously, says international sales director Stephen Winter.

"Everything from the food we source, interaction with the local people, reducing plastic, and recycling water to teaming up with scientists who can use our ships for research,” he says.

Since 1 January, Ponant has stopped using heavy fuel oil and instead burns low-sulphur marine gasoil — a year ahead of the IMO sulphur cap.
