Cow manure isn’t a subject you would expect a cruise line’s team to get excited about, and yet last month when I was on board Havila Polaris for a journey along the Norwegian coast, it had the brand’s chief executive, Bent Martini, waxing lyrical.
Martini’s aim is for the cruise line to be at the forefront of reducing emissions at sea. It is the first ship to sail the route using a combination of battery power and biogas – a renewable fuel created by breaking down animal and food waste.
